NUT (0. Eng. knutu, cf. Dutch noot, Ger. Nuss; allied with Gael. cno; it is not of the same See also:form as See also:Lat. nux)  , a See also:term applied to that class of See also:fruit which consists generally of a single See also:kernel enclosed in a hard See also:shell . Botanically speaking, nuts are one-celled fruits with hardened pericarps, sometimes more or less enveloped in a cupule or See also:cup, formed by the See also:aggregation of the bracts as in the See also:hazel and the See also:acorn . In See also:commerce, however, See also:tale term has a wider application and embraces many fruits having hard woody indehiscent shells or coverings without reference to their enclosed seeds or kernels, besides leguminous pods, and even tuberous roots . A See also:great number of nuts enter into commerce for various purposes, principally as articles of See also:food or See also:sources of oil, and for several ornamental and useful purposes . For the most See also:part the edible nuts are very See also:rich in oil, with only a small percentage of the other carbohydrates, See also:starch, See also:sugar, &c., and they also contain a large proportion of nitrogenous constituents . Thus possessing rich nutrient principles in a highly concentrated See also:form, nuts are by themselves rather difficult of digestion, and the liability of many of them to become rancid is also a source of danger and a hindrance to their See also:free use . Oleaginous nuts used for food are likewise employed more or less as sources of oil, but on the other See also:hand there are many oil-nuts of commercial importance not embraced in the See also:list of edible nuts . On the following See also:page is set out an alphabetical enumeration of the more important nuts, and of products passing under that name, used either as articles of food or as sources of oil .

Soap nut . . . . Washing; ornamental importance are or will be separately noticed, and here further allusion is only made to a few which form current articles of commerce, not otherwise treated of . The bread nut of Jamaica is the fruit of a lofty See also:tree, Brosimum Alicastrum . It is about an See also:inch in See also:diameter, and encloses a single seed, which, roasted or boiled, is a pleasant and nutritious See also:article of food . The souari or surahwa nut, called also the " Butter nut of See also:Demerara," and by fruiterers the " Suwarrow nut," is the fruit of Caryocar nuciferum, a native of the forests of Guiana, growing 8o ft. in height . This is perhaps the finest of all the fruits called nuts . The kernel is large, soft, and even sweeter than the almond, which it somewhat resembles in See also:taste . The few that are imported come from Demerara, and are about the See also:size of an See also:egg, somewhat See also:kidney-shaped, of a rich reddish-See also:brown See also:colour, and covered with large rounded tubercles . The pekea nut, similar in See also:appearance and properties, ,is the produce of Caryocar butyrosum, growing in the same regions of tropical America . The Jamaica cob nut is the produce of a euphorbiaceous tree, Omphalea diandra, the seeds of which resemble in taste the See also:ordinary cob or hazel nut .

The seed, however, contains a deleterious embryo, which must not be eaten . Cola, See also:

kola or goora nuts are the seeds of Cola acuminata (Sterculiaceae), a tree, native of tropical Africa, now introduced into the See also:West Indies and See also:South America . The nuts form an important article of commerce through-out Central Africa, being used over a wide See also:area as a See also:kind of stimulant condiment . The nuts, of which there are numerous varieties, are found to contain a notable proportion of theine, as much as 2.13 %, besides theobromine and other important food-constituents, to which circumstances, doubtless, their valuable properties are due . Coquilla nuts, the hard inner portion (" See also:stone ") of the palm, Attalea funifera, the piassaba of Brazil, are highly valued for turnery purposes . They have an elongated See also:oval form, 3 to 4 in. in length, and being intensely hard they take a See also:fine See also:polish, displaying a richly streaked brown colour . The marking nut, Semecarpus Anacardium, is a fruit closely allied in its source and properties to the cashew nut (q.v.) . The marking nut is a native of the See also:East Indies, where the extremely acrid juice of the shell of the fruit in its unripe See also:state is mixed with quicklime and used as a marking-ink . The juice also possesses medicinal virtues as an See also:external application, and when dry it is the basis of a valuable caulking material and See also:black varnish . The seeds are edible, and the source of a useful oil . Physic nuts are the produce of the euphorbiaceous tree, Curcas purgans, whence a valuable oil, having similar purgative properties to See also:castor oil, is obtained . The plant is a native of South America, but is now found throughout all tropical countries .

Pine nuts are the seeds of several species of Pinus, eaten in the countries of their growth, and also serving to some extent as sources of oil . Of these the most important are the stone pine, Pinus Pinea, of Italy and the Mediterranean coasts, and the See also:

Russian stone pine, Pinus Cembra . The Pinus Sabiniana of See also:California and P . Gerardiana of the Himalayas similarly yield edible seeds . These seeds possess a pleasant, slightly resinous flavour . Ravensara nuts, the fruit of Agathophyllum aromaticum (Lauraceae), a native of Madagascar, is used as a spice under the name of the Madagascar clove nutmeg . The Sapucaya nut, a native of Brazil, is seen occasionally in fruit-shops . It is produced by a large tree, Lecythis 011aria, or " See also:cannon-See also:ball tree." Its specific name is taken from the large See also:urn-shaped capsules, called " See also:monkey-pots " by the inhabitants, which contain the nuts . The sapucaya nut has a sweet flavour, resembling the almond, and if better known would be highly appreciated . It is, however, scarce, as the monkeys and other wild animals are said to be particularly fond of it . This nut, which is of a rich See also:amber-brown, is not unlike the Brazil nut, but it has a smooth shell furrowed with deep See also:longitudinal wrinkles . Soap nuts are the fruits of various species of Sapindus, especially S .

Saponaria, natives of tropical regions . They are so called because their rind or See also:

outer covering contains a principle, saponine, which lathers in water, and so is useful in washing . The pods of See also:Acacia concinna, a native of India, possess the same properties, and are also known as soap nuts .
