Vaccinium vitis-idaea
The Vaccinium vitis-idaea – often called lingonberry and also called cowberry (UK), foxberry, quailberry, mountain cranberry, red whortleberry, lowbush cranberry, mountain bilberry, partridgeberry[1] (in Newfoundland and Cape Breton in Canada), and redberry (in Labrador in Canada) – is a small evergreen shrub in the flowering plant family Ericaceae that bears edible fruit.
It is seldom cultivated, but the fruits are commonly collected in the wild. The native habitat is the circumboreal forests of northern Eurasia and North America, extending from temperate into subarctic climates.
Varieties
There are two very similar regional varieties of Vaccinium vitis-idaea in Eurasia and North America:
* Vaccinium vitis-idaea var. vitis-idaea L., Eurasia. Leaves 10–25 mm long.
* Vaccinium vitis-idaea var. minus Lodd., North America. Leaves 7–20 mm long.
Morphology
Lingonberry shrubs of both varieties are typically 10–40 cm in height and have a compact habit. They prefer some shade (as from a forest canopy) and constantly moist, acidic soil. Nutrient-poor soils are tolerated but not alkaline soils. They are extremely hardy, tolerating −40 °C or lower, but grow poorly where summers are hot.
The plant is only semi-woody but keeps its leaves all winter even in the coldest years, unusual for a broadleaf plant, though they are usually protected from severe cold by snow cover. The plant spreads by underground rhizomes. The bell-shaped white flowers are produced in the early summer. The fruit, actually a false berry, is red and acidic, ripening in late summer to autumn.
The species resembles the related and similar cranberry (Vaccinium oxycoccus, V. microcarpum and V. macrocarpon), differing mainly in having white (not pink) flowers, with the petals partially enclosing the stamens and stigma (the petals are reflexed backwards in cranberries), and rounder, less pear-shaped berries. Other related plants in the genus Vaccinium include blueberries, bilberries, and huckleberries.
Etymology
The name "lingonberry" originates from the Swedish word lingon for the native Lingonberry. Because the names mountain cranberry and lowbush cranberry perpetuate the longstanding confusion between the cranberry and the lingonberry, some botanists have suggested that these names should be avoided.
Uses
Lingonberries collected in the wild are a popular fruit in northern, central and eastern Europe, notably in Scandinavia, the Baltic states, Germany, Austria, Switzerland, Czech Republic, Poland, Slovenia, Slovakia, Romania, Russia, and Ukraine. In some areas they can legally be picked on both public and private lands in accordance with the freedom to roam.
The berries are quite tart, so they are almost always cooked and sweetened before eating in the form of lingonberry jam, compote, juice, or syrup. The raw fruits are also frequently simply mashed with sugar, which preserves most of their nutrients and flavor and even enables storing them at room temperature (in closed but not necessarily sealed containers), but in this condition, they are best preserved frozen. Lingonberries served this way or as compote often accompany game meats and liver dishes. In Sweden and Norway, caribou and deer steak is traditionally served with gravy and lingonberry sauce. Lingonberry preserve is commonly eaten with meatballs and potatoes in Sweden and Norway, and also with pork. In Sweden and Russia, when sugar was still a luxury item, lingonberries were usually preserved simply by putting them whole into bottles of water. This was known as vattlingon (watered lingonberries); the procedure preserved them until next season. This was also a home remedy against scurvy. In Russia this preserve had been known as "lingonberry water" (брусничная вода) and is a traditional soft drink. In Russian folk medicine, lingonberry water was used as a mild laxative. A traditional Finnish dish is sautéed reindeer (poronkäristys) with mashed potatoes and lingonberries, either cooked or raw with sugar. In Finland, lingonberry-porridge is also very popular. In Poland, lingonberries are often mixed with pears to create a sauce served with poultry or game. Lingonberries can also be used to replace red currants when creating Cumberland sauce to give it a more sophisticated taste.
Lingonberries are also popular as a wild picked fruit in Canada in the Canadian province of Newfoundland and Labrador, where they are locally known as partridgeberries. In this region they are also incorporated into jams, syrups, and baked goods.
Lingonberries are a staple item in Sweden, and at the Swedish retailer IKEA. It is often sold as jam and juice in the store and as a key ingredient in dishes. Lingonberries are used to make Lillehammer berry liqueur, and in East-European countries, lingonberry vodka is sold.
Lingonberries are an important food for bears and foxes. Caterpillars of the Coleophoridae case-bearer moths Coleophora glitzella, Coleophora idaeella and Coleophora vitisella are not known to eat anything but lingonberry leaves.
Nutritional properties
Lingonberries contain plentiful organic acids, vitamin C, provitamin A (as beta carotene), B vitamins (B1, B2, B3), and the elements potassium, calcium, magnesium, and phosphorus. In addition to these healthful nutrients, Lingonberries also contain phytochemicals that are thought to counteract urinary-tract infections, and the seeds are rich in Omega-3 fatty acids.
Lingonberries are used in herbal medicine.[citation needed] In pre-modern times, the berries were of major use in keeping people healthy in Sweden through the long winters, when fresh vegetables were not available. A coarse porridge with fat, salt, pork, and lingonberry preserve was a classic meal of the winter, and a large crock of the berries preserved with sugar would be found in every larder. Owing to their high content of benzoic acid, they have the boiling sensation.

Viburnum lentago
Viburnum lentago (Nannyberry, Sheepberry, or Sweet Viburnum) is a species of Viburnum native to the northeastern and midwestern United States, and in southern Canada from New Brunswick west to southeastern Saskatchewan. Isolated populations are found in the Dakotas, Wyoming, Colorado, and the Appalachian Mountains as far south as Kentucky and Virginia.
It is a large shrub or small tree growing to 9 m tall with a trunk up to 25 cm diameter and a short trunk, round-topped head, pendulous, flexible branches. The bark is reddish- to grayish-brown, and broken into small scales. The twigs are pale green and covered with rusty down at first, later becoming dark reddish brown, sometimes glaucous, smooth, tough, flexible, and produce an offensive odor when crushed or bruised. The winter buds are light red, covered with pale scurfy down, protected by a pair of opposing scales. Flower-bearing buds are 2 cm long, obovate, long pointed; other terminal buds are acute, 10–15 mm long, while lateral buds are much smaller. The bud scales enlarge with the growing shoot and often become leaf-like.
Like all viburnums, the leaves are arranged in opposite pairs on the twigs; they are oval, 5-10 cm long and 2-5 cm broad, wedge-shaped, rounded or subcordate at base, with an acuminate apex and a finely serrated margin, and a winged petiole. They open from the bud involute, bronze green and shining, hairy and downy; when full grown are bright green and shining above, pale green and marked with tiny black dots beneath. In autumn they turn a deep red, or red and orange.
The flowers are small, 5-6 mm diameter, with five whitish petals, arranged in large round terminal cymes 5-12 cm diameter; flowering is in late spring. The calyx is tubular, equally five-toothed, persistent; the corolla is equally five-lobed, imbricate in the bud, cream-white, one-quarter of an inch across; lobes acute, and slightly erose. There are five stamens, inserted on the base of the corolla, alternate with its lobes, exserted; filaments slender; anthers bright yellow, oblong, introrse, versatile, two-celled; cells opening longitudinally. The pistil has a one-celled inferior ovary, the style thick, short, light green, and the stigma broad; there is one ovule in each cell. The fruit is a small round blue-black drupe, 8-16 mm long on a reddish stem; it is thick skinned, sweet and rather juicy, and edible. The stone is oblong oval, flattened.
The roots are fibrous, wood is ill-smelling. It grows in wet soil along the borders of the forest, often found in fence corners and along roadsides. The wood is dark orange brown, heavy, hard, close-grained, with a density of 0.7303.
The Sheepberry is one of the largest of the Viburnums. It is admired for its compact habit, its lustrous foliage which insects rarely disfigure, its beautiful and abundant flowers, its handsome edible fruit and its brilliant autumnal color. It readily adapts itself to cultivation, and is one of the best of the small trees of eastern America for the decoration of parks and gardens in all regions of extreme winter cold. It is easily raised from seeds which, like those of the other American species, do not germinate until the second year after they are planted.
Uses
As suggested by the alternative name Sweet Viburnum, the fruit is (unlike that of many Viburnums) edible. The bark and leaves were also used by Native Americans in the preparation of herbal medicines.
It has been hybridized with Viburnum prunifolium in gardens to give the hybrid Viburnum × jackii

Thimbleberry
Rubus parviflorus (Thimbleberry) is a species of Rubus, native to western and northern North America, from Alaska east to Ontario and Michigan,and south to northern Mexico. It grows from sea level in the north, up to 2,500 m altitude in the south of the range.
It is a dense shrub up to 2.5 meters tall with canes no more than 1.5 centimeters in diameter, often growing in large clumps which spread through the plant's underground rhizome. Unlike most other members of the genus, it has no prickles. The leaves are palmate, up to 20 centimeters across, with five lobes; they are soft and fuzzy in texture. The flowers are 2 to 6 centimeters in diameter, with five white petals and numerous pale yellow stamens. The flower of this species is among the largest of any Rubus species, making its Latin species name parviflorus ("small-flowered") a misnomer.It produces a tart edible composite fruit around a centimeter in diameter, which ripen to a bright red in mid to late summer. Like other raspberries it is not a true berry, but instead an aggregate fruit of numerous drupelets around a central core. The drupelets may be carefully removed separately from the core when picked, leaving a hollow fruit which bears a resemblance to a thimble, perhaps giving the plant its name.
The species typically grows along roadsides, railroad tracks, and in forest clearings, commonly appearing as an early part of the ecological succession in clear cut and forest fire areas.
Ecology
Thimbleberry is found in forest understories with typical flora associates including Coastal woodfern, Dryopteris arguta, Trillium ovatum and Smilacina racemosa.
Uses
Thimbleberry fruits are larger, flatter, and softer than raspberries, and have many small seeds. Because the fruit is so soft, it does not pack or ship well, so thimbleberries are rarely cultivated commercially. However, wild thimbleberries make an excellent jam which is sold as a local delicacy in some parts of their range, notably in the Keweenaw Peninsula of Upper Michigan. Thimbleberry jam is easily made by combining equal volumes of berries and sugar and boiling the mixture for two minutes before packing it into jars. The fruits can be eaten raw or dried,but they are not always very palatable.Many parts of the plant were used for a great variety of medicinal purposes by Native Americans.
Thimbleberry plants can be propagated most successfully by planting dormant rhizome segments, as well as from seeds or stem cuttings.
A double-flowered form of the thimbleberry was discovered near Squamish, BC, by Iva Angerman (1903-2008) of West Vancouver, BC.This clone does not appear to be in commerce, but is grown in the Botanic Garden of the University of British Columbia, Vancouver, and in the Native Plant Garden of the Royal British Columbia Museum, Victoria. Another double-flowered thimbleberry was found about 1975 by Bob Hornback on Starrett Hill, Monte Rio, California and given the cultivar name 'Dr. Stasek', after an art instructor at Sonoma State University. This clone is sold by one nursery online.
Cultivars of the plant are used for ornamental purposes, bred for their fragrant flowers and attractive fall foliage

Lansium domesticum
Habit
Lansium domesticum is a medium-sized, single-trunked tree that usually grows from ten to fifteen meters tall.
The plant has pinnately compound leaves that grow to a length of around twenty to fifty centimeters long per leaf. Each fully-grown leaf has five to seven slightly-leathery, obovate leaflets that can reach a length of twenty centimeters each. A very prominent midrib bisects each dark green, glossy leaflet.
Flowers
L. domesticum flowers are hermaphrodite, having both stamen and pistil structures in the same flower. The pale-yellow, fleshy flowers are found in inflorescences of around thirty blossoms, in most cases in a raceme usually around thirty centimeters long.
Fruit
Fruits are ovoid, roundish orbs around five centimeters in diameter, usually found in clusters of two to thirty fruits along the branches and trunk. Each round fruit is covered by yellowish, thick, leathery skin. Underneath the skin, the fruit is divided into five or six slices of translucent, juicy flesh. The flesh is slightly acidic in taste, although ripe specimens are sweeter. Green seeds are present in around half of the segments, usually taking up a small portion of the segment although some seeds take up the entire segment's volume. In contrast with the sweet-sour flavor of the fruit's flesh, the seeds are extremely bitter. The fruit taste has been compared to a combination grape and "perfect" grapefruit with no bitterness. Yet the seeds if bitten have the bitterness of a grapefruit yet stronger. The sweet juicy flesh contains sucrose, fructose, and glucose.
Agriculturally, the tree is grown throughout the entire Southeast asian region, ranging from Southern India to the Philippines for its fruit. In the Philippines, where it is locally referred to as the lanzones, the plant is grown mostly on the southern parts of the island of Luzon, especially in Paete, Laguna, due to the species' narrow range of conditions favorable to its survival. It is also found in abundance on Northern Mindanao particularly in places as Butuan, Cagayan de Oro, and Camiguin. The Camiguin variety is especially sweet and succulent.
In Indonesia, Langsat is very popular fruit in West Kalimantan (Pontianak, Indonesia) and South Sumatra (also called 'Duku'). In Sarawak, northern Borneo, the name Duku is reserved for the larger-sized varieties of Langsat, near the size of golf balls, claimed sweeter and with less sap in the peel. A variety called Dokong exported to mainland Malaysia from Thailand grows tighter in the clusters, giving it a faceted shape, and is preferred by many over the standard Langsat.
Within mainland Asia, the tree is cultivated in Thailand (Thai: ลางสาด, langsat), Vietnam and India, as well as its native Malaysia. Outside the region, it has also been successfully transplanted and introduced to Hawaii and Surinam. It grows well in the wetter areas (120 inches/3 meters or more annual rainfall) of Costa Rica, where it is still very rare, having been introduced decades ago by the United Fruit Company. A major hindrance to its acceptance seems to be that it is very slow in bearing, said to take 12 years from seed. However, air layering from mature trees, as well as grafting, are said to work well and produce much faster
Ecology and life history
It grows wild in Sumatra forests where a wide and longest river in Indonesia lay across the southern part of Sumatra. The river rises and floods the forest lands for a few months, when it subsides, the flood leaves plenty of fallen leaves and twigs enriching and moistening a large area of the forest bed, resulting in ideal conditions for the plant to grow naturally. Local people will come and harvest it as natural forest produce. They climb up the tree with ripe fruits (after observing it), holding with their hands on the smaller branches and shaking it. Mature fruits will fall easily down to the ground. They will then collect it and transport it on a small boat on a nearby river to the villages and sell it. In a good year a 20-year old tree can produce 100 kg of fruits, however fruiting is often uneven.
Etymology and taxonomic history
Lansium domesticum is currently classified within the family Meliaceae.
It is known variously as langsat (Malay); lansones , lansa, langseh, langsep, lanzon, lanzone, lansone(Filipino); langsad (for the type of which its skin is quite sticky to the fruit), longkong (for the type of which the skin is easily peeled off without milky latex) (Thai); duku, langsat, kokosan (Indonesian), Gadu Guda (Sri Lanka), lòn bon and bòn bon (Vietnamese).
In certain parts of the Visayas, the fruit is called buwa-buwa or bowa-bowa, and the tree is called buwahan or bowahan.
Importance to humans
Langsat fruits are usually eaten fresh, but may be canned in syrup. Seedless sections can be dried like raisins, which is done in the Philippines.
Nutritional composition per 100 g langsat fruit Carbohydrate 7.8-14.2 g Protein 0.4-0.7 g Calcium 10-19 mg Phosphorus 20 mg Iron 1 mg Thiamine 0.05 mg Riboflavin 0.02 mg Niacin 0.5 mg Vitamin C 4-13.4 mg
Several parts of the plant have medicinal uses. The fruit peel is dried and burned to repel mosquitoes; it is also used to treat intestinal parasites and diarrhea. Powdered seeds are used to reduce fever, and the bark is used to treat malaria and scorpion stings

Loquat
The loquat (Eriobotrya japonica) is a fruit tree in the family Rosaceae, indigenous to southeastern China. It was formerly thought to be closely related to the genus Mespilus, and is still sometimes known as the Japanese medlar.
It is an evergreen large shrub or small tree, with a rounded crown, short trunk and woolly new twigs. The tree can grow to 5–10 m tall, but is often smaller, about 3–4 m.
The leaves are alternate, simple, 10–25 cm long, dark green, tough and leathery in texture, with a serrated margin, and densely velvety-hairy below with thick yellow-brown pubescence; the young leaves are also densely pubescent above, but this soon rubs off.
Loquats are unusual among fruit trees in that the flowers appear in the autumn or early winter, and the fruits are ripe in late winter or early spring. The flowers are 2 cm diameter, white, with five petals, and produced in stiff panicles of three to ten flowers. The flowers have a sweet, heady aroma that can be smelled from a distance.
Loquat with fruits.
Loquat fruits, growing in clusters, are oval, rounded or pear-shaped, 3–5 cm long, with a smooth or downy, yellow or orange, sometimes red-blushed skin. The succulent, tangy flesh is white, yellow or orange and sweet to subacid or acid, depending on the cultivar. Each fruit contains five ovules, of which one to five mature into large brown seeds. The skin, though thin, can be peeled off manually if the fruit is ripe.
The fruits are the sweetest when soft and orange.
Use
The loquat is comparable with its distant relative, the apple, in many aspects, with a high sugar, acid and pectin content. It is eaten as a fresh fruit and mixes well with other fruits in fresh fruit salads or fruit cups. Firm, slightly immature fruits are best for making pies or tarts. The fruits are also commonly used to make jam, jelly, and chutney, and are often served poached in light syrup.
Loquat syrup is used in Chinese medicine for soothing the throat like a cough drop. The leaves, combined with other ingredients and known as pipa gao (枇杷膏; pinyin: pípágāo; literally "loquat paste"), it acts as a demulcent and an expectorant, as well as to soothe the digestive and respiratory systems. Loquats can also be used to make light wine.
Like most related plants, the seeds (pips) and young leaves of the plant are slightly poisonous, containing small amounts of cyanogenetic glycocides (including amygdalin) which release cyanide when digested, though the low concentration and bitter flavour normally prevents enough being eaten to cause harm.
In Japan, it is eaten fresh or sometimes canned because the flesh is sweet. However, the waste ratio is 30% or more, due to the size of the seed. Among other things, it is processed to confectionery including jellies and the jam.
Eaten in quantity, loquats have a gentle but noticeable sedative effect, with effects lasting up to 24 hours.[citation needed]
It is also fermented into a fruit wine, sometimes using just the crystal sugar and white liquor. Lemon or lemon zest is often paired with the wine because the fruit has very low acidity. Aficionados also enjoy a sake made exclusively from the seed, which has an aroma much like apricot kernel. Due to the presence of cyanogenetic glucosides, bulk consumption may pose a risk of cyanide poisonings.
Cultivation
The Loquat is easy to grow in subtropical to mild temperate climates where it is often grown as an ornamental tree, and second for its delicious fruit. The boldly textured foliage adds a tropical look to gardens, contrasting well with many other plants. There are many named cultivars, with orange or white flesh.
Etymology
The name loquat derives from lou4 gwat1, the Cantonese pronunciation of its old classical Chinese name (simplified Chinese: 芦橘; traditional Chinese: 蘆橘; pinyin: lújú, literally "reed orange"). In modern Chinese, it is more commonly known as pipa (Chinese: 枇杷; pinyin: pípá), from the resemblance of its shape to that of the Chinese musical instrument pipa (琵琶). Likewise, in Japanese it is called biwa, similarly named from the corresponding musical instrument, biwa. It is also known as the "Japanese medlar", an appellation used in many languages: nêspera or magnório (Portuguese), níspero (Spanish), lokaat (Hindi), japanska mušmula or nešpula (Croatian), naspli (Maltese), nespola (Italian), náspolya (Hungarian), nespra (Catalan), nèfle du Japon or bibasse (French), néspera (Galician). Other names include: שסק sheseq (Hebrew), إسكدنيا Iskidunya, إكيدنيا Ik(k)idunya, Aki Dini,Igadinya or Bashmala بشملة (Arabic), Akkadeneh or Akka Dhuniya (Lebanese), zger or Nor Ashkhar (Armenian), mushmala (Georgian), mushmolla verore (summer medlar) (Albanian), μούσμουλο/μούσμουλα moúsmoulo/moúsmoula (sg/pl) or mespilia (Greek), Japanse (wol)mispel (Dutch), yeni dünya, or Malta Eriği in Turkish, mespila in Cyprus, mousmoula in Greece, despoles (δέσπολες) in Crete , Pibasy in Malagasy,мушмула (mušmulá) in Russian, and lukwart[3] in Afrikaans. The Armenian name Nor Ashkhar and the Turkish name yeni dünya literally mean "new world", while the everyday Turkish name for the fruit, Malta eriği, means 'Maltese plum', indicating perhaps confusion over the fruit's origin.
Nutritional Value
The loquat is low in saturated fat and sodium, and is high in vitamin A, dietary fiber, potassium, and manganese Template:Http://www.wolframalpha.com/input/?i=loquat.
Coppertone Loquat
The Coppertone Loquat (Eriobotrya x 'Coppertone') is a cross between a loquat and an Indian Hawthorn [4] and is a popular shrub in the southern United States.

Tamarind
Tamarind (Tamarindus indica) (from Latinization of Arabic: تمر هندي tamar hindi = Indian date) is a tree in the family Fabaceae. The genus Tamarindus is monotypic (having only a single species).
Origin
Tamar Indicus is endemic to tropical Africa, particularly where it continues to grow wild in Sudan; it is also cultivated in Cameroon, Nigeria and Tanzania. It reached India likely through human transportation and cultivation several thousand years prior to the Common Era.It was in India that it was first described by Western botanists as Tamarindus indica, the Latin derivative of the Persian and the Arabic name commonly attributed to it: "tamar al-Hind" or the Hindu [sic: Hindustani] date. It is widely distributed throughout the Tropical belt, from Africa to India, and throughout South East Asia, Taiwan and as far as China. In the 16th century, it was heavily introduced to Mexico as well as South America by Spanish and Portuguese colonists, to the degree that it became a common ingredient in everyday living
Description
The tamarind is a long-lived, medium-growth bushy tree which attains a maximum crown height of 12.1 to 18.3 metres (40 to 60 feet). The crown has irregular vase-shaped outline of dense foliage.
Leaves are evergreen, bright green in colour, elliptical ovular, arrangement is alternate, of the pinnately compound type, with pinnate venation and less than 5 cm (2 inches) in length. The branches droop from a single, central trunk as the tree matures and is often pruned in human agriculture to optimize tree density and ease of fruit harvest. At night, the leaflets close up. The tamarind does flower, though inconspicuously, with red and yellow elongated flowers. Flowers are 2.5 cm wide (one inch) five-petalled borne in small racemes, yellow with orange or red streaks. Buds are pink due as the 4 sepals are pink and are lost when the flower blooms. The tree grows well in full sun in clay, loam, sandy and acidic soil types, with a high drought and aerosol salt (wind-borne salt as found in coastal area) resistance.
The fruit of the tamarind is most commonly reserved for consumption, whether raw or cooked or prepared in some other manner, according to the regional and cultural palate. The fruit itself is an elongated rod, 12 to 15 cm (3 to 6 inches) in length, and covered in a hard, brown exterior.
The fleshy, juicy, acidulous pulp of the fruit is mature when coloured brown or reddish-brown. The fruit is considered ripe when the pods are easily pried open with fingers. The fruit pod contains anywhere between 1 and 12 flat, glossy brown seeds. These may be used by children in traditional board games such as Chinese checkers (China), dakon (Java), among others.
Seeds can be scarified to enhance germination. They retain germination capability after several months kept dry.
The tamarind is best described as sweet and sour in taste, and high in acid, sugar, vitamin B and interestingly for a fruit, calcium.
The tamarinds of India fruit with longer pods containing 6-12 seeds, whereas African and West Indian versions have short pods containing 1-6 seeds. Fruit of the South American tamarinds are identical to the original African variant.
A Tamarind seedling
Tamarind flowers
As a tropical species, it is frost sensitive. The pinnate leaves with opposite leaflets giving a billowing effect in the wind. Tamarind timber consists of hard, dark red heartwood and softer, yellowish sapwood.
Tamarind is harvested by pulling the pod from its stalk. A mature tree may be capable of producing upto 175 kg (350 lb) of fruit per annum. Veneer grafting, shield (T or inverted T) budding, and air layering may be used to propagate desirable selections. Such trees will usually fruit within 3 to 4 years if provided optimum growing conditions.
Alternative names
Alternative names for tamarind include Imli, Indian date, translation of Turkish language "Demirhindi" Arabic تمر هندي tamr hindī.
Globally, it is most numerous in India, where it is widely distributed and has a long history of human cultivation. Many Indian regional languages have their own unique name for the tamarind fruit. In Sanskrit, it is called tintiDi. In Oriya it is called tentuli; in Bengali the tentul; Hindi and in Urdu imli; Gujarati the amli. and Marathi and Konkani the chinch. In Sinhala call it the siyambala; Telugu chintachettu (tree) and chintapandu (fruit extract); Tamil and Malayalam the puli (புளி) and in Kannada it is called hunase (ಹುಣಸೆ) and in Cook Islands Maori is called 'tamarene'
In Indonesia, tamarind is known as the asam (or asem) Jawa (means Javanese asam), which in the Indonesian language, translates as Javanese sour [sic: fruit] (though the literature may also refer to it as sambaya). In Malaysia, it is called asam in the Javanese-influenced Malay language of Melayu (modern Central Sumatra). In the Philippines, tamarind is referred to as sampaloc, which is occasionally rendered as sambalog in Tagalog and sambag in Cebuano. Vietnamese term is me. In Taiwan it is called loan-tz. In Myanmar it is called magee-bin (tree) and magee-thee (fruit).The tamarind is the provincial tree of the Phetchabun province of Thailand (in Thailand it is called ma-kham). In Malagasy it is called voamadilo and kily.
In Colombia, Mexico, Puerto Rico and Venezuela it is called tamarindo. In the Caribbean, tamarind is sometimes called tamon.
Tamarind (Tamarindus indica) should not be confused with the Manila tamarind (Pithecellobium dulce), which is a different plant, though also of Fabaceae.
Cultivation
Although native to Sudan and tropical Africa, India is the single largest consumer and commercial producer of tamarind.
In India there are extensive tamarind orchards producing 275,500 tons (250,000 MT) annually. The pulp is marketed in northern Malaya.
The tamarind has also long been naturalized in Indonesia, Malaysia and Philippines and the Pacific Islands. Thailand has the largest plantations of the ASEAN nations, followed by Indonesia, Myanmar and the Philippines
One of the first tamarind trees in Hawaii was planted in 1797.
The tamarind was introduced into tropical America, mainly Mexico, Bermuda, the Bahamas, and the West Indies by either Portuguese or Spanish colonists or perhaps by African slaves or seamen much earlier, in the 1600s CE.
In the United States, it is a large-scale commercial crop common (second in net production quantity to India) in the mainly Southern states due to tropical and semi-tropical climes notably South Florida, and as a shade and fruit tree, along roadsides and in dooryards and parks. There are large commercial plantations in Brazil, Costa Rica, Cuba, Guatemala, Mexico, Nicaragua and Puerto Rico.
Culinary uses
The fruit pulp is edible and popular. The hard green pulp of a young fruit is considered by many to be too sour and acidic, but is often used as a component of savory dishes, as a pickling agent or as a means of making certain poisonous yams in Ghana safe for human consumption.
The ripened fruit is considered the more palatable as it becomes sweeter and less sour (acidic) as it matures. It is used in desserts as a jam, blended into juices or sweetened drinks, sorbets, ice-creams and all manner of snack. It is also consumed as a natural laxative.
In Western cuisine it is found in Worcestershire sauce;HP sauce; and the Jamaican-produced Pickapeppa sauce.
In Indian cuisine it is common. Imli Chutney and Pulusu use it. Along with tamarind, sugar and spices are added to (regional) taste for chutneys or a multitude of condiments for a bitter-sweet flavor. The immature pods and flowers are also pickled and used as a side dish. Regional cuisines such as Maharashtra, Tamil Nadu and Andhra Pradesh use it to make Rasam, Sambhar, Vatha Kuzhambu and Puliyogare. In Andhra Pradesh & Tamil Nadu, tender leaves of tamarind are used along with lentils and it is also dried and used in place of ripe tamarind for mild flavour.
Tamarind tree, India
In Guadeloupe, tamarind is known as Tamarinier and is used in jams and syrups.
In Mexico, it is sold in various snack forms: dried and salted; or candied (see for example pulparindo or chamoy snacks). The famous agua fresca beverage, iced fruit-bars and raspados all use it as the main ingredient. In the US, Mexican immigrants have fashioned the "agua de tamarindo" drink and many other treats. Tamarind snacks such as Mexico's Pelon Pelo Rico, are available in specialty food stores worldwide in pod form or as a paste or concentrate.
In Egypt, a sour, chilled drink made from tamarind is popular during the summer.
A traditional food plant in Africa, tamarind has potential to improve nutrition, boost food security, foster rural development and support sustainable landcare.
In southern Kenya, the Swahili people use it to garnish legumes and also make juices. In Madagascar, its fruits and leaves are a well-known favorite of the Ring-tailed Lemurs, providing as much as 50% of their food resources during the year if available. In Northern Nigeria, it is used with millet powder to prepare Kunun Tsamiya, a traditional Pap mostly used as breakfast, and usually eaten with bean cake.
The Javanese dish gurame and more so ikan asem, also known as ikan asam (sweet and sour fish (commonly a carp or river-fish) is popular throughout Indonesia, Malaysia and Singapore. Tamarind is also common in Manado, Sulawesi and Maluku cuisines.
In Myanmar, young and tender leaves and flower buds are eaten as a vegetable. A salad dish of tamarind leaves, boiled beans, and crushed peanuts topped with crispy fried onions is very popular in rural Myanmar.[citation needed]
In the Philippines, tamarind is used in foods like sinigang soup, and also made into candies. The leaves are also used in sinampalukan soup.
In Thailand a specific cultivar has been bred specifically to be eaten as a fresh fruit, famous for being particular sweet and minimally sour. It is also sometimes eaten preserved in sugar with chili as a sweet-and-spicy candy. Pad Thai, a Thai dish popular with Westerners often include tamarind for its tart/sweet taste (with lime juice added for sourness and fish sauce added for saltiness). A tamarind-based sweet-and-sour sauce served over deep-fried fish is also a common dish in central Thailand.
Medicinal uses
Phytochemical studies revealed the presence of tannins, saponins, sesquiterpenes, alkaloids and phlobatamins and other extracts active against both gram positive and gram negative bacteria, at temperatures of 4–30 °C (39–86 °F). Studies on the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the extracts on the test organisms showed that the lowest MIC and the MBC were demonstrated against Salmonella paratyphi, Bacillus subtilis and Salmonella typhi and the highest MIC and MBC was exhibited against Staphylococcus aureus.
Throughout Asia and Africa it is common for health remedies. In Northern Nigeria, fresh stem bark and fresh leaves are used as decoction mixed with potash for the treatment of stomach disorder, general body pain, jaundice, yellow fever and as blood tonic and skin cleanser. In Indonesia, Malaysia and Philippines and Javanese traditional medicine use asem leaves as a herbal infusion for malarial fever, the fruit juice as an anti-septic, and scurvy and even cough cure. Fruit of the tamarind is also commonly used throughout South East Asia as a poultice applied to foreheads of fever sufferers.
Tamarind is used as in Indian Ayurvedic Medicine for gastric and/or digestion problems, and in cardioprotective activity.
In animal studies, tamarind has been found to lower serum cholesterol and blood sugar levels. Due to a lack of available human clinical trials, there is insufficient evidence to recommend tamarind for the treatment of hypercholesterolemia (high cholesterol) or diabetes.
Based on human study, tamarind intake may delay the progression of fluorosis by enhancing excretion of fluoride. However, additional research is needed to confirm these results.
Excess consumption has been noted as a traditional laxative.
Other medicinal uses include: Anthelminthic (expels worms), antimicrobial, antiseptic, antiviral, asthma, astringent, bacterial skin infections (erysipelas), boils, chest pain, cholesterol metabolism disorders, colds, colic, conjunctivitis (pink eye), constipation (chronic or acute), diabetes, diarrhea (chronic), dry eyes, dysentery (severe diarrhea), eye inflammation, fever, food preservative, food uses (coloring), gallbladder disorders, gastrointestinal disorders, gingivitis, hemorrhoids, indigestion, insecticide, jaundice, keratitis (inflammation of the cornea), leprosy, liver disorders, nausea and vomiting (pregnancy-related), paralysis, poisoning (Datura plant), rash, rheumatism, saliva production, skin disinfectant/sterilization, sore throat, sores, sprains, sunscreen, sunstroke, swelling (joints), urinary stones, wound healing (corneal epithelium)
Carpentry uses
In temples, especially in Buddhist Asian countries, the fruit pulp is used to polish brass shrine furniture, removing dulling and the greenish patina that forms.
The wood is a bold red color. Due to its density and durability, tamarind heartwood can be used in making furniture and wood flooring. A tamarind switch is sometimes used as an implement for corporal punishment.[citation needed]
Horticultural uses
Tamarind trees are very common in throughout all Asia and indeed tropical world as both an ornamental, garden and cash-crop. The tamarind has recently become popular in bonsai culture, frequently used in Asian countries like Indonesia, Taiwan and the Philippines. In the last Japan Airlines World Bonsai competition, Mr. Budi Sulistyo of Indonesia won the second prize with an ancient tamarind bonsai.

Malus sieversii
Malus sieversii is a wild apple native to the mountains of Central Asia in southern Kazakhstan, Kyrgyzstan, Tajikistan, Northern Afghanistan and Xinjiang, China. It has recently been shown to be the sole ancestor of most cultivars of the domesticated apple (Malus domestica). It was first described (as Pyrus sieversii) in 1833 by Carl Friedrich von Ledebour, a German naturalist who saw them growing in the Altay Mountains.
It is a deciduous tree growing to 5-12 m tall, very similar in appearance to the domestic apple. Its fruit is the largest of any species of Malus, up to 7 cm diameter, equal in size to many modern apple cultivars. Unlike domesticated varieties its leaves go red in autumn: 62.2% of the trees in the wild do this compared to only 2.8% of the 2170 English cultivated varieties. The species is now considered vulnerable to extinction.
History and importance
For many years, there was a debate about whether M. domestica evolved from chance hybridization among various wild species. Recent DNA analysis by Barrie Juniper, Emeritus Fellow in the Department of Plant Sciences at Oxford University and others, has indicated, however, that the hybridization theory is probably false. Instead, it appears that a single species still growing in the Ili Valley, on the northern slopes of the Tien Shan mountains at the border of northwest China and Kazakhstan, is the progenitor of the apples we eat today. Leaves taken from trees in this area were analyzed for DNA composition, which showed them all to belong to the species M. sieversii, with some genetic sequences common to M. domestica.
However, another recent DNA analysis showed that Malus sylvestris has also contributed to the genome of M. domestica. A third species that has been thought to have made contributions to the genome of the domestic apples is Malus baccata, but there is no hard evidence for this in older apple cultivars.
It is named alma in Kazakhstan; the region in Kazakhstan thought to have the oldest such plants includes the city of Alma-ata, or "Grandfather of Apples".
Renewed interest
These and other Malus species have been used in some recent breeding programmes to develop apples suitable for growing in climates unsuitable for M. domestica, mainly for increased cold tolerance.
Malus sieversii has recently been cultivated by the United States Agricultural Research Service, in hopes of finding genetic information of value in the breeding of the modern apple plant. Some, but not all, of the resulting trees show unusual disease resistance. The variation in their response to disease on an individual basis is, itself, a sign of how much more genetically diverse they are than their domesticated descendants.

Crowberry
Crowberry (Empetrum) is a small genus of dwarf evergreen shrubs that bear edible fruit. They are commonly found in the northern hemisphere, from temperate to subarctic climates, and also in the Andes of South America and on Tristan da Cunha (South Atlantic Ocean). The typical habitat is on moorlands, tundra and muskeg, but also in spruce forests. They are also found abundantly on the dune slacks and sand dunes of the Danish Island of Fanø as well as all over Iceland.
Species of crowberry include: E. nigrum (Crowberry), E. eamesii (Rockberry), E.rubrum and E. hermaphroditum. All are evergreen mat forming shrubs, with small, light green needle-like leaves 3-10 mm long. The flowers are small and plain looking. The fruit is a fairly dry black berry, smaller than the alpine bearberry, but with somewhat better flavour, and looks similar to a blueberry.
The genus and related ones such as Ceratiola and Corema were for most of the 20th century classified in their own family Empetraceae, but molecular data, leaf morphology, and other considerations point to their inclusion in the Ericaceae (specifically, as a tribe within the subfamily Ericoideae). This tribe does share a number of distinctive morphological features, which seem to be associated with wind pollination.
Use
In subarctic areas, crowberry has been a vital addition to the diet of the Inuit and the Sami. After waning popularity, the crowberry is again regaining its reputation as an edible berry. It gives a steady crop and the gathering is relatively easy. The high concentration of anthocyanin pigment can be used as a natural food dye. The Dena'ina (Tanaina) harvest it for food, sometimes storing in quantity for winter, and like it mixed with lard or oil. They keep well in a cool place without any special preparation.
The berries are usually collected in the fall of the year but if not picked they may persist on the plant and can be picked in the spring. The raw berries are mealy and tasteless. The Inuit and Native Americans mix them with other berries, especially the blueberry. Cooking enhances the flavor. They make good pie and jelly.
The leaves and stems are used in Dena'ina medicine for diarrhea and stomach problems; they are boiled or soaked in hot water, and the strained liquid drunk. Some claim the berry juice is good for kidney trouble.
In Dena'ina plantlore in the Outer and Upper Inlet area of Lake Clark, the root is also used as a medicine, being used to remove a growth on an eye and to heal sore eyes. The roots are boiled and the eyes are washed with the strained, cooled tea, to which a little sugar may be added. Some people say blackberry stems can be used in the same way for these ailments.
Crowberries contain mostly water. Their vitamin content is low, as is also the concentration of volatile liquids, the lack of which makes them almost odorless. The acidity is lower than is typically encountered in forest berries, and benzene acids are almost absent.
Crowberries are also occasionally grown as ornamental plants in rockeries, notably the yellow-foliage cultivar Empetrum nigrum 'Lucia' (photo, left).

Borassus
Borassus (Palmyra Palm) is a genus of six species of fan palms, native to tropical regions of Africa, Asia and New Guinea. They are tall palms, capable of growing up to 30 m high. The leaves are long, fan-shaped, 2 to 3 m in length. The flowers are small, in densely clustered spikes, followed by large, brown, roundish fruits.
Species
* Borassus aethiopum - African Palmyra Palm (and other names) (tropical Africa)
* Borassus akeassii - Ake Assi's Palmyra Palm (West Africa)
* Borassus flabellifer - Asian Palmyra palm/Lontar palm/Doub palm/Sea Coconut (southern Asia and southeast Asia)
* Borassus heineanus - New Guinea Palmyra Palm (New Guinea)
* Borassus madagascariensis - Madagascar Palmyra Palm (Madagascar)
* Borassus sambiranensis - Sambirano Palmyra Palm (Madagascar)
Cultivation and uses
Palmyra Palms are economically useful, and widely cultivated in tropical regions. The palmyra palm has long been one of the most important trees of Cambodia and India, where it is used over 800 different ways. The leaves are used for thatching, mats, baskets, fans, hats, umbrellas, and as writing material.
In Indonesia the leaves of this plant were used in the ancient culture as papers.
In Cambodia the tree is a national flora symbol/emblem that is seen growing around Angkor Wat. The sugar palm can live over 100 years.
Palmyra palms were used in ancient India to write on, as a kind of papyrus. Leaves of suitable size and shape and texture, with sufficient maturity are chosen. The leaves are then seasoned by boiling in salt water with turmeric powder. This acts as a preservative. The leaves are then dried. When they are dry enough, the faces of the leaves are polished with pumice stone. Then they are cut in the proper size. A hole is cut out in one corner. Each leaf will have four pages. The writing is done with a stylus. The writing is of a very cursive and interconnected style. The leaves are then tied up as sheaves.
The stalks are used to make fences and also produce a strong, wiry fiber suitable for cordage and brushes. The black timber is hard, heavy, and durable and is highly valued for construction e.g. wharf pilings.
The tree also yields many types of food. The young plants are cooked as a vegetable or roasted and pounded to make meal. The fruits are eaten roasted or raw, and the young, jellylike seeds are also eaten. A sugary sap, called toddy, can be obtained from the young inflorescence, either male or female ones. toddy is (called "kallu (కల్లు)" in Telugu. The toddy is fermented to make a beverage called arrack, or it is concentrated to a crude sugar called jaggery/palm sugar. It is called Gula Jawa (Javanese sugar) in Indonesia and is widely used in the Javanese cuisine. In addition, the tree sap is taken as a laxative, and medicinal values have been ascribed to other parts of the plant.
This tree is highly respected in Tamil culture and is called "karpaha" (celestial tree), because all its parts can be used. The Palmyra tree is the official tree of Tamil Nadu. In Tamil Nadu / Jaffna the seeds are planted and made to germinate and the fleshy sprouts (below the surface) are boiled and eaten. It is very fibrous and nutritious
The germinated seed's hard shell is also cut open to take out the crunchy kernel which tastes like a sweeter Water Chestnut.
The ripe fibrous outer layer of the palm fruits are also boiled / heated in fire and eaten.
When the fruit is tender the kernel, inside the hard shell, is like a jelly and delicious as well. The fruit is an excellent coolant in the hot coastal summers, rich in minerals.
When the crown of the tree is cut we get an edible cake, from which the leaves grew out from.

Prunus virginiana
The Choke Cherry (Prunus virginiana) is a species of bird cherry (Prunus subgenus Padus) native to North America, where it is found almost throughout the continent except for the deep south and the far north.
Growth
It is a suckering shrub or small tree growing to 5 m tall. The leaves are oval, 3-10 cm long, with a coarsely serrated margin. The flowers are produced in racemes of 15-30 in late spring (well after leaf emergence). The fruit are about 1 cm diameter, range in color from bright red to black, with a very astringent, sour taste. The very ripe berries are dark in color and less astringent than the red berries.
Etymology
The chokeberries, genus Aronia, are often mistakenly called chokecherries. This naming confusion is easy to understand considering there is a cultivar of the chokecherry Prunus virginiana 'Melanocarpa' and a species of chokeberry named Aronia melanocarpa. In fact, the two plants are not close relatives within their subfamily Spiraeoideae.
Characteristics
Chokecherries are very high in antioxidant pigment compounds, like anthocyanins. They share this property with chokeberries, further contributing to confusion.
Varieties
Prunus virginiana is sometimes divided into two varieties, P. virginiana var. virginiana (the eastern chokecherry), and P. virginiana var. demissa (the western chokecherry)
The wild Chokecherry is often considered a pest, as it is a host for the tent caterpillar, a threat to other fruit plants. However, there are more appreciated cultivars of the chokecherry, such as 'Goertz', which has a non-astringent, and therefore palatable, fruit. Research is being done at the University of Saskatchewan to find and create new cultivars to increase production and processing.
Chokecherry is closely related to the Black Cherry (Prunus serotina) of eastern North America; it is most readily distinguished from that by its smaller size (Black Cherry can reach 30 m tall), smaller leaves, and sometimes red ripe fruit. The Chokecherry leaf has a finely serrated margin and is dark green above with a paler underside, while the Black Cherry leaf has numerous blunt edges along its margin and is dark green and smooth.
The name chokecherry has also been used (as 'Amur Chokecherry') for the related Manchurian Cherry or Amur Cherry (Prunus maackii).
The bark of chokecherry root was once made into an asperous-tasting concoction used to ward off or treat colds, fever and stomach maladies by native Americans The chokecherry fruit can be used to make a tasty jam, jelly, or syrup, but the bitter nature of the fruit means you need a lot of sugar to sweeten the preserves.
Chokecherry is toxic to horses, especially after the leaves have wilted (such as after a frost or after branches have been broken) because wilting releases cyanide and makes the plant sweet. About 5-10 kg of foliage can be fatal. Symptoms of a horse that has been poisoned include heavy breathing, agitation, and weakness. The leaves of the chokecherry serve as food for caterpillars of various Lepidoptera. See List of Lepidoptera which feed on Prunus.
In 2007, Governor John Hoeven signed a bill naming the chokecherry the official fruit of the state of North Dakota.
