Cocoanut, Double.—This is the fruit of another lofty palm, Lodoicea Sechellarum, and is usually considered the largest member of the order. It is a native of the Seychelles islands, in the Indian ocean. It is said to reach a hight of a hundred feet, with a stem two feet in diameter. The fruit is a large, oblong nut, with a rather thin rind or husk, and when this is removed the nut appears to be double, or two oblong nuts firmly united, a kind of twin formation, the entire nut weighing from thirty to forty pounds. These immense nuts are produced in bunches of eight to ten, the cluster sometimes weighing from three to four hundred pounds. It is supposed that these nuts require about ten years to grow and mature. They are useless as food, but the shells are manufactured into various useful articles by the natives, and they are also transported to other countries and valued as curiosities. There is a great demand for the leaves of this palm for making hats, baskets, etc., and as the trees have to be cut down to obtain them, they are becoming rather scarce.
[Cola nut], Kola nut or Goora nut.—The fruit of a small tree, native of the warmer parts of western Africa, and known to botanists as Cola acuminata, and of the Sterculiad family (Sterculiaceæ). In its native country it grows thirty to forty feet high. The leaves are oblong-elliptical, six to eight inches long, and pointed (acuminate), and from this it probably derived its specific name. The flowers are yellow, and produced in axillary racemes, and succeeded by simple bean-like pods, each containing several nut-like seeds, which the natives call cola or goora nuts. These nuts have long been an article of trade among the native tribes of Africa, they being valued for their supposed efficacy in allaying thirst, promoting digestion, giving strength, and preventing exhaustion during the performance of hard manual labor. This tree was early introduced into the West Indies and Brazil, but its reputation in Africa does not appear to have been sustained it its Western habitat.
Coquilla nut.—The fruit of the Piassaba palm, Attalea funifera, a native of Brazil, where it grows about thirty feet high. The fruit is produced in bunches, and are each about three inches long, covered with a thin rind. The nut is very hard, and is used as a substitute for bone and ivory in the manufacture of articles for the household.
[Coquito nut.]—This is the fruit of the wing-leaved palm of Chile, Jubæa spectabilis. It is a moderately tall species, and closely resembles, in general habit, the date palm. The nuts are edible, but they are of secondary importance, this palm being valued mainly for the sweet sap issuing from the stem when cut down, this continuing to exude from it for weeks after it is severed from the roots. The sap is gathered and boiled, and when reduced to the consistency of molasses becomes an article of commerce, under the name of Meil de Palma or palm honey.
Cream nut.—A local name of [Brazil nut].
Dawa nut.—See [Litchi nut].
Earth nut, or [earth chestnut], etc.—A small, low-growing, herbaceous plant of the carrot family (Umbelliferæ), common in waste or uncultivated grounds in Great Britain and other countries of northern Europe. Formerly botanists supposed there were two species, but of late only one, the Bunium bulbocastanum. On the roots there are small, nut-like tubers, of a sweetish taste, and they are eaten by children, either in the raw state or after being roasted. These tubers have various local names, and in addition to the above, they are called kipper nuts, and pig nuts in England, but a familiar local name in Scotland is lousy nuts, because it is said that eating them is sure to breed lice. But this story may have been invented by parents to deter their children from digging and eating the roots of wild plants. Willdenow, in naming this species, certainly recognized its edible qualities, and that children were fond of it, else he would not have called it an earth chestnut,—bulbo, bulb, and castanum from castanea, the chestnut.
Elk nut.—See [Oil nut].
