Description:
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: Neotype (designated by Almeda, 2002): Costa Rica, Tonduz 2115 (BR!).
Description: Shrubs or small trees 2-6 m tall, the young branchlets, elevated primary leaf veins beneath, and inflorescences sparsely furfuraceous-puberulent to glabrate. Leaves 3-5-nerved, elliptic to elliptic-lanceolate, 7.5-16 X 3-5 cm, adaxially glabrous, abaxially sparingly furfuraceous-puberulent to glabrate, apex gradually acuminate, base acute to rounded, the margin remotely and obscurely denticulate to subentire; petioles 1-4.5 cm long. Panicle 5-8 cm long; flowers 5-merous on pedicels 1-2 mm long, the early-deciduous subulate bracteoles 0.5-1.5 mm long. Hypanthia obscurely and deciduously puncticulate-lepidote but often appearing glabrous; Calyx tube 0.5 mm long, the oblong apically rounded lobes 0.5-0.7 mm long, the bluntly tuberculate teeth 0.5 mm long, appressed to but not exceeding the lobes. Petals obovate, glabrous, 2-2.5 X 2-2.5 mm. Stamens isomorphic; anthers 4-celled, cuneate, 1.5 mm long, white or white flushed with pink, the broad pore somewhat retuse and ventrally inclined; connective thickened dorso-basally into a bluntly lobulate spur and prolonged ventro-basally into a bilobulate appendage. Style glabrous, 4-5 mm long; stigma capitate; ovary 3-locular, 2/3 inferior, apex elevated into a lobulate glabrous collar; berry 4-5 X 4-5 mm, blue-green then turning purple at maturity. Seeds ovoid, obscurely granulate, 0.5 mm long.
Habitat and Distribution: Locally common, cloud forest, elfin forest. 1300-3000 m. NICARAGUA (Moreno 510, CAS); COSTA RICA (Almeda et al. 3110, CAS). (Endemic).
