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: Honduras, Williams 15828 (F!).
Description: Shrub or small tree 0.5-4 m tall with terete to ± compressed uppermost cauline internodes. Young vegetative buds covered with a deciduous indument of stellate hairs, otherwise the internodes, petioles, adaxial leaf surfaces, inflorescence branches, hypanthia, and calyx are glabrous. Leaves of a pair equal to somewhat unequal in size; blades 3-5-nerved or if 3-5-plinerved then the innermost pair of primary veins diverging from the midvein 1-3 mm above the blade base, elliptic to linear-lanceolate, 2-8 (-12) x 0.5-2.6 cm, the apex acuminate, the base rounded varying to obtuse, the margin serrulate (at least distally), the abaxial surface essentially glabrous but with dense tufts of stalked-stellate hairs at the point where the innermost pair of primary veins diverge from the midvein at the base of the blade; petioles 0.3-2.5 cm long. Inflorescence an openly branched panicle 4-8 cm long, the 5-merous flowers subsessile or on pedicels 0.5-0.75 mm long, the early deciduous bracteoles linear-oblong, 2-3 x 0.25 mm. Calyx tube ca. 1 mm long, the calyx lobes broadly depressed-rounded, 1 x 2.5 mm, the exterior calyx teeth filiform, 3-4 mm long, greatly exceeding and projecting beyond the calyx lobes and commonly hooked apically or somewhat curled when dry. Petals white or white flushed with pink, glabrous, obovate, 8-9 (-14) x 4-6 mm. Anthers somewhat unequal in size, yellow, oblong-subulate and ± arcuate, alternately 8 mm and 6 mm long with a solitary ventrally inclined pore; connective thickened dorsally but neither prolonged abaxially the thecae nor appendaged. Style glabrous, 1-1.1 cm long; stigma punctiform; ovary 3-locular, 1/3 inferior, the apex elevated into a glabrous ± truncate cone in fruit; berry 6-8 x 5-8 mm when dry, purple-black at maturity. Seeds ovoid to ± triangular, the testa rounded to angulate, smooth and glossy, 1 mm long.
Habitat and Distribution: Locally common in cloud forest and oak-pine forest. MEXICO: Chiapas (Daniel et al. 8409, CAS); GUATEMALA (Heyde & Lux 6137, US); HONDURAS (Davidse et al. 35172, CAS); EL SALVADOR (Croat 42315, CAS). (Endemic)
