  • Juglans Regia
    Juglans regia Family: Juglandaceae Common names: Common walnut Local names: Akhrot, Khor, Danti-akhrot (Joshimath) Ayurvedic name: Shailbhav, Akshot, Karpraal Plant profile: Juglans regia is a large tree native to southeastern Europe and western Asia. The generic name Juglans is a combination of the Latin jovis (the king of gods) and glans (nut). The leaves are imparipinnate with the leaflets in pairs, sessile, oblong, rounded at base, acuminate. The fruit is a fleshy drupe, oblong, ovoid and olive green colour when immature. The shell is hard and thick. And the kernels are pale white, thick and oily. The tree is found growing wild throughout the Himalayas and hills of Assam at altitudes of 1000-3300 m. In Himachal Pradesh, the tall giant trees of wild varieties are found in shaded ravines in Chamba, Kullu, Shimla, and Sirmour. Recently, people have started cultivating superior, grafted varieties of walnuts for plantations. Flowering takes place in March-April and fruiting in September- October. The bark of the tree is also peeled and the dried fruit taken away from the tree during the month of September and October. Under natural conditions the fruits fall to the ground and around the tree. The exocarp cracks and rots off. The nuts, however, are subject to attack by birds, monkeys and rodents and large quantities of them are destroyed. The bark is popularly known as Dandasa and is illegally traded. Medicinal uses: • Parts used: Root, bark, leaves and fruit. • Active principles: Juglandic acid, juglonone, barium and arsentic in traces are present. The fruits contain oxalic acid, resin and a fixed oil of drying nature.

  • Pandanaceae) from Malesia
    BLUMEA 32 (1987) 427-441 New taxa of Pandanus (Pandanaceae) from Malesia and Papuasia B.C. Stone Academy of Natural Sciences of Philadelphia, Department of Botany, 19th& Parkway, Philadelphia, PA 19103, U. S. A. INTRODUCTION Monographic studies in Pandanaceae continue to yield previously unrecognized taxa both at specific and higherranks. In Pandanus, with the increase ofknowledge of staminate structures becoming available through better collectionsand more critical observations, use of staminate characters integrated with previously known data is providing important new insights into infrageneric taxa and their affinities, as well as completing the fundamental descriptions at species rank important for both sys- tematic and ecological studies. In the results reported here two new species, Pandanus calvus and P. kosteri, and two new sections, Hastatistigma (based on P. vinaceus) and Macrokurzia (based on P. daymanensis) are proposed. Two species previously known only frompistillate materials, P. cernuifolius and P. irregularis, are clarified by description of staminate specimens, while in the case of P. cope- landii, a previously unrecognized staminate feature is described. Field data for the inadequately known species P. leptocarpus are provided, and the first illustrationsof the of P.

  • European Water Chestnut Fact Sheet Invasive Exotic Plants of Canada Fact Sheet No
    European Water Chestnut Fact Sheet Invasive Exotic Plants of Canada Fact Sheet No. 13 European Water Chestnut - water chestnut, bull nut, Jesuit nut, water-caltrop Trapa natans L. Water-nut Family - Trapaceae Field Recognition European water chestnut is an aquatic plant, which is usually rooted in the mud and bears a rosette of floating leaves at the tip of the submersed stem. Stems are elongate and flexuous and typically about a metre long but may reach about 5 metres in length. The conspicuously toothed leaf blades are 2-4 cm long and rhombic in outline (with four sides); the long, spongy, inflated leaf stalks are up to about 15 cm long and provide the buoyancy for the terminal leafy portion of the plant. Green, feather-like, submersed leaves (considered by some to be roots) with very fine segments are present on the submersed stem and numerous finely branched roots develop along the lower stem that assist in anchoring the plant to the substrate. The inconspicuous flowers with their four white petals, each about 8 mm long, are borne singly on erect stalks located in the central area of the leafy rosette. The fruit is a four-horned, barbed, nut-like structure, about 3 cm wide, that develops under water. Habitat Plants grow in quiet streams, ponds, freshwater regions of estuaries and on exposed mud flats. History of Introduction and Spread European water chestnut is native to Eurasia, being found in paleotropical and warm temperate regions. It has become naturalized in Australia and in northeastern North America. It is a member http://infoweb.magi.com/~ehaber/factnut.html (1 of 6) [8/29/2002 3:32:35 PM] European Water Chestnut Fact Sheet of a small family that includes a single genus and, depending on the view of the specialist, one, three or as many as thirty species (Heywood 1978).

  • NOTES on the HISTOLOGY of the ALMOND ^ in Connection with A
    NOTES ON THE HISTOLOGY OF THE ALMOND ^ By V. A. PEASE Associate Microscopist, Food Research Division, Chemical and Technological Re- search, Bureau of Chemistry and Soils, United States Department of Agriculture INTRODUCTION In connection with a study of one of the technological problems involved in the salting of domestic almonds, some rather interesting data on the histology of the almond kernel or seed have been assem- bled. This material is presented here not only on account of its gen- eral interest to histologists, but because it may afford some assistance to the trade in developing a method for the determinination of types if not of varieties of shelled almonds as they appear in the open market. MATERIAL The material studied^ consists of four varieties of domestic almonds and four varieties of imported almonds. The domestic almonds, Nonpareil, Ne Plus Ultra, I. X. L., and Drake, are among the leading varieties grown in California, and the imported nuts, Etna, Marcona, Valencia, and Alicante, originally brought from Italy and Spain, are largely used by bakers and confectioners. The domestic nuts are paper and soft shelled, while tbe imported nuts are standard and hard shelled. On the basis of the hardness of the shell, these samples would be classed as follows:^ f I. X. L. Paper < Ne Plus Ultra. [ Nonpareil. Soft Drake. Standard Marcona. {Valencia. Etna. Alicante (?). The almond fruit is a typical drupe; that is, it consists of a single seed surrounded by a stony endocarp which forms the shell, a fleshy mesocarp, and an outer skin or epicarp. The mesocarp is tough and leather}^ and, with its protecting epicarp, splits away from the endo- carp at maturity.
