The fruit varies greatly in form, but with innu- merable transitions between its variations. Bentham admits the seven following sections:— I. Samanea.—This section whose type is, as indicated by its name, P. Saman Benth. [Inc/a ScmoM W., Spec, iv. 1026;—Z sahitaris H. B. K., Nov. Gen. et Spec, vi. 304;—Mimosa Samam Jacq., IVagm., t. 9;—Calliandra tuhulosa Bsnis.), contains twenty-five species of unarmed trees with stipules ill developed or absent. The pinnules are indefinite in number' The infiorescences are axillary, fascicled or col- lected into terminal panicles. The pod is straight, bowed, circinate or cochlear, coriaceous thick and indehiscent, or dehiscent without subsequent distortion of the valves. The seeds are arillate. (Veiioz., M. Flmm., xi. t. 24, 30 (?).—Jacq., Fragm., t. 9.—K., Mimas., t. 21 Gbiseb., n. Bnt. W. Ind., 225). This last author makes the species of the section belong to Calliandra, though the pods do not present tbe dehiscence peculiar to that genus. II. Chloroleucon.—Trees unarmed or occa- sionally possessing axillary spines, stipules.
