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: Holotype: Nicaragua, Stevens 12148 (CAS!).
Description: Trees 4.5-10 m tall, the branchlets stellate-furfuraceous when young but glabrate with age. Leaves 3-nerved (excluding the inconspicuous submarginal pair), elliptic to elliptic-lanceolate, 11-23 X 4-7.5 cm, adaxially glabrous, abaxially densely ferrugineous stellate-tomentose, apex acuminate, base acute to obtuse, the margin entire; petioles 1-2.1 cm long. Panicle 3-5 cm long; flowers 6-merous, sessile, the deciduous bracteoles linear-lanceolate, 0.5-1.5 X 0.25-0.5 m. Hypanthia densely stellate furfuraceous; calyx lobes acute, obtuse or broadly deltoid, appearing fused or closely connivent in bud, 0.5 X 1 mm when fully expanded, abscissing as a ring after anthesis, the subulate to obconic calyx teeth 0.5 mm long. Petals oblong and concave, 2-3 X 1 mm. Anthers somewhat anisomorphic, linear to linear-subulate, alternately 2.5 mm and 2 mm long, white, the larger with a ventrally inclined pore and connective prolonged dorso-basally into a trilobate or cordiform appendage, the smaller with a truncate to dorsally inclined pore and a minute dorsally trilobate connective prolongation. Style sparsely glandular-puberulent, 4-5.5 mm long; stigma truncate; ovary 3-4-locular, 1/2 inferior, apex minutely papillate; berry 5.5-6 X 4-5.5 mm, purple at maturity. Seeds ovoid to pyriform, minutely papillate, 1.5-2 mm long.
Habitat and Distribution: Local and uncommon, rain forest. 75-400 m. HONDURAS (Saunders 1306, CAS); NICARAGUA (Stevens 8398; CAS); COSTA RICA (Allen 5814, CAS). (Endemic).
Notes: [Description based only on Mesoamerican specimens.]
