93. CARYOTA URENS.--This fine palm is a native of Ceylon, and is also found in other parts of India, where it supplies the native population with various important articles. Large quantities of toddy, or palm-wine, are prepared from the juice, which, when boiled, yields very good palm sugar or jaggery, and also excellent sugar candy. Sago is also prepared from the central or pithy part of the trunk, and forms a large portion of the food of the natives. The fiber from the leaf stalk is of great strength; it is known as Kittool fiber, and is used for making ropes, brushes, brooms, etc. A woolly kind of scurf, scraped off the leaf stalks, is used for calking boats, and the stem furnishes a small quantity of wood.
94. CASIMIROA EDULIS.--A Mexican plant, belonging to the orange family, with a fruit about the size of an ordinary orange, which has an agreeable taste, but is not considered to be wholesome. The seeds are poisonous; the bark is bitter, and is sometimes used medicinally.
95. CASSIA ACUTIFOLIA.--The cassias belong to the leguminous family. The leaflets of this and some other species produce the well-known drug called senna. That known as Alexandria senna is produced by the above. East Indian senna is produced by _C. elongata_. Aleppo senna is obtained from _C. obovata_. The native species, _C. marylandica_, possesses similar properties. The seeds of _C. absus_, a native of Egypt, are bitter, aromatic, and mucilaginous, and are used as a remedy for ophthalmia. _C. fistula_ is called the Pudding-Pipe tree, and furnishes the cassia pods of commerce. The seeds of _C. occidentalis_, when roasted, are used as a substitute for coffee in the Mauritius and in the interior of Africa.
96. CASTILLOA ELASTICA.--This is a Mexican tree, which yields a milky juice, forming caoutchouc, but is not collected for commerce except in a limited way.
97. CASUARINA QUADRIVALVIS.--This Tasmanian tree produces a very hard wood of a reddish color, often called Beef wood. It is marked with dark stripes, and is much used in some places for picture frames and cabinetwork. This belongs to a curious family of trees having no leaves, but looking like a gigantic specimen of Horse-tail grass, a weed to be seen in wet places.
