Botanical Name; Elaeagnus umbellata
Family: Elaeagnaceae
Genus: Elaeagnus
Species: E. umbellata
Kingdom: Plantae
Order: Rosales

Common Names :Japanese silverberry, Umbellate oleaster, Autumn-olive, Autumn elaeagnus, or Spreading oleaster

Habitat :Elaeagnus umbellata is  native to eastern Asia from the Himalayas east to Japan. Because airborne nitrogen can be fixed in its roots, it has the capability to grow in infertile habitats.Grows in thickets and thin woods in the lowland and hills

Description :
These plants are deciduous shrubs or small trees growing 3.5 m tall, with a dense, thorny crown. The leaves are alternate, 4–10 cm long and 2–4 cm wide, entire but with a wavy margin. The leaves are silvery when they leaf out early in spring due to numerous tiny scales, but turn greener above as the scales wear off through the summer (unlike the related E. angustifolia, which remains silvery to leaf fall). The flowers are clustered 1-7 together in the leaf axils, fragrant, with a four-lobed pale yellowish-white 1 cm long corolla. The fruit is a round drupe 1/4 to 1/3 inches (0.65 to 0.85 cm) long, silvery-scaled yellow, ripening to red dotted with silver or brown.

It is in flower from May to June, and the seeds ripen from Sep to November. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees.It can fix Nitrogen.  It is noted for attracting wildlife.It is hardy to zone 3 and is not frost tender.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils, requires well-drained soil and can grow in nutritionally poor soil.The plant prefers acid, neutral and basic (alkaline) soils..It cannot grow in the shade.It requires dry or moist soil and can tolerate drought.The plant can tolerate maritime exposure.

Cultivation:
Succeeds in most soils that are well-drained, though it dislikes shallow chalk soils. It prefers a soil that is only moderately fertile, succeeding in very poor soils and in dry soils. Prefers a light sandy loam and a sunny position. Established plants are very drought resistant. A very hardy plant, tolerating temperatures down to at least -40°c. This species is somewhat similar to E. multiflora, but it flowers a few weeks later. Sometimes cultivated for its edible fruit, there are some named varieties. ‘Cardinal’ and ‘Red Wing’ are very good fruiting forms (developed for ornament and not for fruit quality). ‘Jazbo’ has been bred for its edible fruits which are said to be ripe when ‘they drop into your hand’. This makes them valuable in breeding programmes to develop easily harvested fruits. Flowers are rich in nectar and very aromatic, they are much visited by bees. Polymorphic. This species is notably resistant to honey fungus. Plants can fruit in 6 years from seed. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby. An excellent companion plant, when grown in orchards it can increase yields from the fruit trees by up to 10%.

Propagation:
Seed – best sown as soon as it is ripe in a cold frame. It should germinate in late winter or early spring, though it may take 18 months. Stored seed can be very slow to germinate, often taking more than 18 months. A warm stratification for 4 weeks followed by 12 weeks cold stratification can help. The seed usually (eventually) germinates quite well. Prick out the seedlings into individual pot as soon as they are large enough to handle and plant out when they are at least 15cm tall. Cuttings of half-ripe wood, 7 – 10cm with a heel, July/August in a frame. Good percentage[78]. Cuttings of mature wood of the current year’s growth, 10 – 12cm with a heel, November in a frame. Leave for 12 months. Fair to good percentage. Layering in September/October. Takes 12 months

Edible Uses
Edible Parts: Fruit;  Seed.

Fruit – raw or cooked. Juicy and pleasantly acid, they are tasty raw and can also be made into jams, preserves etc. The fruit must be fully ripe before it can be enjoyed raw, if even slightly under-ripe it will be quite astringent. The fruit contains about 8.3% sugars, 4.5% protein, 1% ash. The vitamin C content is about 12mg per 100g. Mature bushes in the wild yield about 650g of fruit over 2 – 3 pickings. The harvested fruit stores for about 15 days at room temperature. The fruit is about 8mm in diameter and contains a single large seed. Seed – raw or cooked. It can be eaten with the fruit though the seed case is rather fibrous

Medicinal Uses:
Astringent;  Cancer;  Cardiac;  Pectoral;  Stimulant.

The flowers are astringent, cardiac and stimulant.  The seeds are used as a stimulant in the treatment of coughs. The expressed oil from the seeds is used in the treatment of pulmonary affections.     The fruit of many members of this genus is a very rich source of vitamins and minerals, especially in vitamins A, C and E, flavanoids and other bio-active compounds. It is also a fairly good source of essential fatty acids, which is fairly unusual for a fruit. It is being investigated as a food that is capable of reducing the incidence of cancer and also as a means of halting or reversing the growth of cancers.

Other Uses
Fuel;  Hedge;  Hedge.

Very tolerant of maritime exposure, it makes a good informal hedge, succeeding even in very exposed positions.  The plants make a reasonable wind-protecting screen, they are about as wide as they are tall. They make a good companion hedge, enriching the soil and fertilizing neighbouring plants. The wood is a good fuel.

Known Hazards : Elaeagnus umbellata has the potential of becoming one of the most troublesome adventive shrubs in the central and eastern United States.

Astragalus multiceps

Botanical Name : Astragalus multiceps
Family : Leguminosae
Genus : Astragalus
Synonyms : Astragalus bicuspis – Fisch.
Common Name :Kandiara


Habitat
:E. Asia – W. Himalayas, to 3,500 metres in Garhwal, Kumaon and Simla.   Found at elevations of 1300 – 3300 metres in Tibet

Description:
Shrub growing to 0.45m.

CLICK & SEE

The plant prefers light (sandy) and medium (loamy) soils and requires well-drained soil. The plant prefers acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It requires dry soil.

Cultivation:
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it could succeed outdoors in many parts of this country. The following notes are based on the general needs of the genus. Requires a dry well-drained soil in a sunny position. Plants are intolerant of root disturbance and are best planted in their final positions whilst still small. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby. Many members of this genus can be difficult to grow, this may be due partly to a lack of their specific bacterial associations in the soil.

Propagation:
Seed – best sown as soon as it is ripe in a cold frame. A period of cold stratification may help stored seed to germinate. Stored seed, and perhaps also fresh seed, should be pre-soaked for 24 hours in hot water before sowing – but make sure that you do not cook the seed. Any seed that does not swell should be carefully pricked with a needle, taking care not to damage the embryo, and re-soaked for a further 24 hours. Germination can be slow and erratic but is usually within 4 – 9 weeks or more at 13°c if the seed is treated or sown fresh. As soon as it is large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter, planting them out into their permanent positions in late spring or early summer, after the last expected frosts.

Edible Uses
Edible Parts: Flowers.

The calyx of the flower is eaten and has a sweetish flavour.

Medicinal Uses
Demulcent; Emollient.

The seeds are demulcent and emollient. They are used in the treatment of colic and leprosy.


Known Hazards :
Many members of this genus contain toxic glycosides. All species with edible seedpods can be distinguished by their fleshy round or oval seedpod that looks somewhat like a greengage. A number of species can also accumulate toxic levels of selenium when grown in soils that are relatively rich in that element.

Botanical Name:Pongamia glabra
Family : Fabaceae
Kingdom: Plantae
Division: Magnoliophyta
Class: Magnoliopsida
Order: Fabales
Genus: Pongamia
Species: P. pinnata

Other Name:Pongamia pinnata, Indian Beech Tree, Honge Tree, Pongam Tree, Panigrahi

Habitat : Originated in India and is found throughout Asia.

Description:
It is a deciduous legume tree that grows to about 15-25 meters in height with a large canopy which spreads equally wide. The leaves are a soft, shiny burgundy in early summer and mature to a glossy, deep green as the season progresses. Small clusters of white, purple, and pink flowers blossom on their branches throughout the year, maturing into brown seed pods. The tree is well suited to intense heat and sunlight and its dense network of lateral roots and its thick, long taproot make it drought tolerant. The dense shade it provides slows the evaporation of surface water and its root nodules promote nitrogen fixation, a symbiotic process by which gaseous nitrogen (N3) from the air into NH3+ (a form of nitrogen available to the plant). Withstanding temperatures slightly below 0°C to 50°C and annual rainfall of 50–250 cm, the tree grows wild on sandy and rocky soils, including oolitic limestone, but will grow in most soil types, even with its roots in salt water…

Constituents:Seeds contain 27% bitter and dark (sherry) coloured fixed oil (pongamia oil). The oil contains toxic flavonoids including 1.25% karanjin and 0.85% pongamol alkaloid, resin, mucilage and sugar.

Uses:
Known by many names (Indian Beech, Pongam, Honge, Ponge, and Karanj among other) it is a tree that is well-adapted to arid zones and has many traditional uses. It is often used for landscaping purposes as a windbreak or for shade due to the large canopy and showy fragrant flowers. The bark can be used to make twine or rope and it also yields a black gum that is used to treat wounds caused by poisonous fish. The flowers are used by gardeners as compost for plants requiring rich nutrients. Juices from the plant, as well as the oil, are antiseptic and resistant to pests. In addition the Pongam tree has the rare property of producing seeds of 25-35% lipid content. The seed oil is an important asset of this tree having been used as lamp oil, in soap making, and as a lubricant for thousands of years. This oil is rapidly gaining popularity as a source of feedstock for bio-diesel production.

Medicinal Uses: .Seed extract is used for Skin problems, in tanning, Shops, infestation of grains, piscidal, insecticidal, nematicidal and bactericidal activity.

According to Ayurveda, Karanj is anthelmintic, alexipharmic and useful in diseases of eye, vagina, skin. The oil has been used to treat tumours, wounds, ulcers, itching, enlargement of spleen and abdomen, urinary discharges. It also reputed to cure biliousness, piles, head pains, leucoderma, skin diseases and wounds.

The fruits and sprouts are used in folk remedies for abdominal tumors in India, the seeds for keloid tumors in Sri Lanka, and a powder derived from the plant for tumors in Vietnam. In sanskritic India, seeds were used for skin ailments. Today the oil is used as a liniment for rheumatism. Leaves are active against Micrococcus; their juice is used for colds, coughs, diarrhea, dyspepsia, flatulence, gonorrhea, and leprosy. Roots are used for cleaning gums, teeth, and ulcers. Bark is used internally for bleeding piles. Juices from the plant, as well as the oil, are antiseptic. It is said to be an excellent remedy for itch, herpes, and pityriasis versicolor. Powdered seeds are valued as a febrifuge, tonic and in bronchitis and whooping cough. Flowers are used for diabetes. Bark has been used for beriberi. Juice of the root is used for cleansing foul ulcers and closing fistulous sores. Young shoots have been recommended for rheumatism. Ayurvedic medicine described the root and bark as alexipharmic, anthelmintic, and useful in abdominal enlargement, ascites, biliousness, diseases of the eye, skin, and vagina, itch, piles, splenomegaly, tumors, ulcers, and wounds; the sprouts, considered alexeteric, anthelmintic, apertif, and stomachic, for inflammation, piles and skin diseases; the leaves, anthelmintic, digestive, and laxative, for inflammations, piles and wounds; the flowers for biliousness and diabetes; the fruit and seed for keratitis, piles, urinary discharges, and diseases of the brain, eye, head, and skin, the oil for biliousness, eye ailments, itch, leucoderma, rheumatism, skin diseases, worms, and wounds. Yunani use the ash to strengthen the teeth, the seed, carminative and depurative, for chest complaints, chronic fevers, earache, hydrocele, and lumbago; the oil, styptic and vermifuge, for fever, hepatalgia, leprosy, lumbago, piles, scabies, and ulcers.

Cautions: Generally non-toxic and non-sensitizing. Use well diluted. Avoid during pregnancy.

Research Efforts:
The seed oil has been found to be useful in diesel generators and, along with Jatropha, it is being explored in hundreds of projects throughout India and the third world as feedstock for biodiesel. It is especially attractive because it grows naturally through much of arid India, having very deep roots to reach water, and is one of the few crops well-suited to commercialization by India’s large population of rural poor. Several unelectrified villages have recently used Honge oil, simple processing techniques, and diesel generators to create their own grid systems to run water pumps and electric lighting.

In 2003 the Himalayan Institute of Yoga Science and Philosophy as part of its Biofuel Rural Development Initiative started a campaign of education and public awareness to rural farmers about Pongamia in two Indian states. One of the Himalayan Institute’s partners developed a consistently high yield scion that reduced the time it takes to mature from 10 years to as little as three. To help the farmers in the transition from traditional crops to the Pongamia tree the Indian government has contributed over $30 million in low-interest loans and donated 4.5 million KG of rice to sustain impoverished drought-stricken farmers until the trees begin to produce income. Since the project began in 2003 over 20 million trees have been planted and 45,000 farmers are now involved.

In 2006 the Himalayan Institute began looking at locations in Africa to transplant the Pongamia tree into. Initially they began in Uganda but due to the lack of infrastructure and growing desertification the project has been growing very slowly. They have also begun a project in the Kumbo region of Cameroon where conditions are better. There has been some suggestions that the Pongamia tree could be grown all the way across the continent as a way to prevent the encroachment of the Sahara.

The University of Queensland node of the Center for Excellence in Legume Research, under the directorship of Proffessor Peter Gresshoff, in conjunction with Pacific Renewable Energy are currently working on Pongamia Pinnata for commercial use for the production of Biofuel. Projects are currently focussed on understanding aspects of Pongamia including root biology, grafting, salinity tolerance, and the genetics of the oil production pathways.
