Description Author and Date: Frank Almeda, based on Almeda, F. (2009). Melastomataceae. In: G. Davidse, M. Sousa-Sânchez, S. Knapp, & F. Chiang (eds.), Flora Mesoamericana: Cucurbitaceae a Polemoniaceae. 4(1): 164-338.

Type: Lectotype (designated by Rendle, fide Howard & Kellogg, 1986): Jamaica, (LINN 559.10).

Description: Shrubs 2.5-5 m tall, the young branchlets, petioles, leaf veins beneath, inflorescences, and hypanthia sparsely to moderately beset with deciduous stellulate hairs. Leaves (3-)5-nerved, ovate-lanceolate to oblong-ovate, (5.5-)10-20(-25) X 3-6 cm, adaxially glabrous, abaxially glabrous on the actual surface, apex attenuate to gradually acuminate, base obtuse to rounded, the margin obscurely denticulate to entire; petioles 1-4 cm long. Panicle (3-)5-10(-15) cm long; flowers 5-merous, sessile and secund on the outermost branchlets, the persistent bracteoles linear-oblong to narrowly subulate, 0.5-1 mm long. Calyx tube 0.25 mm long, the rounded lobes mostly 0.25 mm long, the tuberculate teeth 0.25 mm long but not projecting beyond the lobes. Petals oblong-obovate, 2.5-3 X 1.5-2 mm, minutely papillate. Stamens somewhat unequal; anthers linear-oblong, white, alternately 3 mm and 2.5 mm long, the larger with a ventrally inclined pore, the smaller with a truncate to retuse pore; connective of the larger anthers barely prolonged but dilated basally into a gently lobed biauriculate appendage that forms a dorso-basal collar, connective of the smaller anthers dilated ventro-basally into a smaller bilobed appendage. Style glabrous, 5-6 mm long; stigma clavate-truncate; ovary 3-locular, 1/2 inferior, apex minutely papillate to glabrate; berry 5 X 5 mm, blue-black at maturity. Seeds ovoid and rounded, obscurely rugulate, 0.5 mm long.
