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: Panama, Shattuck 335 (F!).
Description: Shrubs or small trees 1-4 m tall, the young branchlets, petioles, elevated primary leaf veins beneath, and inflorescences moderately to densely covered with flexuous barbellate or plumulose hyaline hairs and moderately underlain with minute oblong glands. Leaves 5-7-nerved, broadly elliptic to elliptic-ovate, 10-29(-39) X (6-)11-21.5 cm, adaxially glabrous, abaxially moderately beset with a mixture of simple, barbellate, and minute glandular hairs on the secondary and higher order venation, apex short-acuminate, base broadly rounded and obliquely cordate, the margin inconspicuously undulate-denticulate; petioles 2-8 cm long. Panicle 6-15 cm long; the 5-merous flowers on pedicels 1.5-2.5 mm long, the persistent bracteoles subulate, 0.5-1 mm long. Hypanthia sparingly beset with a mixture of stellulate, barbellate, and minute glandular hairs; calyx tube 0.5 mm long, the undulate apiculate lobes 0.25-0.5 mm long, the tuberculate exterior teeth ca. 0.25 mm long, inserted on the calyx tube and not projecting beyond the lobes. Petals glabrous, obovate-oblong, 2.5-4(-5) X 1.5(-3) mm. Stamens isomorphic; anthers oblong, 1.5-2 mm long, yellow, the pore truncate to retuse; connective neither prolonged nor appendaged. Style glabrous, 3-4 mm long; stigma unexpanded; ovary 5-locular, 3/4 inferior, apex sparingly glandular puberulent; berry 5-6 X 5-6 mm, purple-black at maturity. Seeds broadly deltoid in outline, smooth and rounded-angulate, the raphe expanded on all sides to form an inflated wing-like border, 0.5-0.75 mm long.
Habitat and Distribution: Rare, stream margins, rain forest. 50-1000 m. Colombia. NICARAGUA (Araquistain 3075; CAS); COSTA RICA (Zamora et al. 1267, CAS); PANAMA (Herrera et al. 1095, CAS).
