130. Calliandra paniculata C. D. Adams, Phytologia 20: 310. 1970. — "C. D. Adams 11154 . . . between Two Rivers and Gut River, Manchester Parish, Jamaica, ... 13 May 1962." — Holotypus, UCWI n.v.; isotypus, BM!.

C. paniculata sensu Adams, Fl. Pl. Jamaica 334. 1972.

Slender shrubs ±1-2 m, resembling C. comosa in habit and especially in the terminal efoliate panicles of pseudoracemes and in falcate pods, perhaps not specifically distinct but apparently different in evident (but thin) pubescence, in manifestly pulvinulate lfts, in proportionately wider lfts and in somewhat smaller calyces, the lf-stks and axes of inflorescence pilosulous with gray hairs to 0.5 mm, some lfts remotely ciliolate. Stipules lance-subulate or triangular ±2-2.5 mm. Lf-formula ii/7-10; lf-stks 14—22 mm, the petiole 4—12 mm, the one interpinnal segment as long or longer; rachis of distal pinnae 3.5-4 cm, the longer interfoliolar segments to 5 mm; lft-pulvinules ±0.45-0.6 x 0.4 mm; lfts scarcely graduated, the blades elliptic or oblong-elliptic from broadly semicordate base, broadly obtuse apiculate, the larger ones ±12—15(—18) x 4.5-6(-7) mm, 2.2-3 times as long as wide. Inflorescence scarcely 1 dm diam; peduncles solitary and (few) geminate, the longer ones 12-18 mm; capitula 3-6-fld, the flowers obscurely pedicellate, the perianth greenish, glabrous except for microciliolate calyx, this weakly ±10-nerved; calyx shallowly turbinate-campanulate ±1.1 x 1.5 mm, the depressed-deltate teeth 0.2 mm; corolla 5.4 mm, the ovate lobes 2 mm; androecium 26-merous, 19-20 mm, the tube 6.3 mm, the stemonozone and intrastaminal disc of C. comosa. Pods not seen ripe, in youth gray-pilosulous, apparently otherwise like those of C. comosa.

On rocks at ±6 m, known only from the type-locality on the s. coast of Jamaica near 77°30'W. — Fl. IV-VI.
