Ivory nut.—There are two species of palms producing nuts hard enough to be employed as a substitute for ivory, in the manufacture of small articles of domestic use. But the one best known to commerce under the name of ivory nut is the fruit of Phytelephas macrocarpa, native of New Granada and other parts of Central America. This palm is a low-growing and almost decumbent species, the stem seldom more than six to eight inches in diameter; but the leaves are of immense length, or from fifteen to twenty feet, growing in bundles, or clusters. The fruit consists of about forty nuts, enclosed in a rough, spiny husk, of a globular form, produced on a short footstalk growing from the axis of the leaves, the whole bunch weighing from twenty to thirty pounds. They are two inches long, slightly triangular, and covered with a thin, pulpy coat, which becomes dry, papery and brittle when thoroughly dried, but when in its green state it is sometimes utilized by the natives for making a favorite beverage. The ripe nuts are very solid, hard, and when polished resemble ivory. Immense quantities of these nuts are imported into this country, as well as Europe, and used as a substitute for bone and ivory for making buttons, toys, and similar small articles.

Jicara nut.—A local name, in some of the Central American States for the Calabash (Crescentia Cujete). A low-growing, rather rough tree, with simple leaves, usually three growing together on a broad leafstalk. The fruit is extremely variable, both in size and form, but mainly globose, and two to four inches in diameter. The shell is very hard, and largely used for drinking cups, and these are sometimes highly ornamented on the outside. The kernel is scarcely edible, but is used by the natives as a medicine.

[Litchi nut] or leechee nut.—I am inclined to think that the affix of "nut" to this Oriental fruit is an Americanism, and not used elsewhere. There are three distinct species of this fruit known among the Chinese, under the name of Litchi, Longan or Long-yen, and Rambutan, all the product of the Nepheliums, a genus of the soapberry family (Sapindaceæ). By some of the earlier botanical works the litchi is placed either in the genus Dimocarpus or Euphoria. Within the past few years this fruit has appeared in our markets, in consequence of the increased trade with Oriental countries, and facilities for rapid transit across the continent. The litchi is a globular fruit, about one inch in diameter (Fig. 103), with a thin, chocolate-brown colored shell covered with wart-like protuberances. When fresh the shell is filled with a white, jelly-like pulp, in the center of which there is one rather large, smooth brown seed. The pulp is of a most delicious sub-acid flavor, but it is often rather dry and stale in the nuts which reach us from China and Japan. The tree producing this fruit is seldom more than twenty-five feet high, with rather sturdy twigs and branches, the leaves composed of about seven oblong pointed leaflets. This is said to be one of the most popular of Oriental fruits, and the trees would probably succeed in many of the Southern States and in California. It is now on trial in Florida, having been introduced there in 1886. It has been fruited in England many times, but always under glass, where the plants receive protection and artificial heat. A full description of this species, accompanied by a superb colored plate of the Nephelium or Dimocarpus Longana, appeared in the "Transactions of the London Horticultural Society," 1818, p. 402. There are not only a large number of species of the Nepheliums bearing edible fruit, but, as might be expected from their long and extensive cultivation, many local varieties, especially in the southern provinces of China and throughout the islands of tropical Asia. The Dawa of the Fiji islands is the fruit of N. pinnatum, a tree growing sixty feet high, and forming extensive forests on those islands. At some future time we may be receiving the dawas under the name of Fiji nuts.
