Castilla Cerv.

Monoecious or dioecious trees (cf. 0. F. Cook, in Science, ser. 2. 18:437. 1903; H. Pittier, in Contrib. U. S. Nat. Herb. 13:253. 1910), the branches unarmed. Leaves alternate, distichous, closely and minutely ciliate-denticulate to essentially entire; stipules fully amplexicaul. Inflorescences axillary, solitary or clustered, involucrate, the staminate discoid and conduplicate-flabellate, the pistil-late discoid or subglobose. Staminate flowers essentially unorganized and naked, with stamens bearing oval anthers apically affixed to the filament. Pistillate flowers more or less coherent, with a fleshy accrescent conic-tubular perianth and a subinferior ovary, the stigma 2-lobed almost to the base of the central style. Fruit a more or less fleshy syncarp.
