"Palm is a natural order of endogenous plants, the products of which are of extreme importance and utility to man. The size of the leaves varies, some being only a few inches in length, while in others they attain the enormous proportions of 35 feet in length by 5 or 6 feet in breadth. The flowers are small individually, but numerous, usually of a yellow tint, and in some species powerfully odorous. The fruit when ripe is berry-like, drupaceous, plum-like, or, as in the cocoanut, nut-like. The sugar palm is a native of the Moluccas, Cochin-China, and the Indian Archipelago, and is of immense value to the natives of these countries on account of its various products. It yields an abundant sweet sap, from which a chocolate-colored sugar is made. The sap fermented makes an intoxicating drink variously named by the inhabitants of the different countries. From the pith of the stem sago is obtained in great quantity, a single stem yielding as much as from 150 to 200 pounds."—(Charles Leonard-Stuart, 1911)
