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: Colombia, Triana 4003 (BM!).
Description: Shrub or small tree 2.5-3.5 m tall, the uppermost rounded-quadrate cauline internodes, petioles of uppermost leaves, primary and secondary veins on abaxial surfaces of leaf blades, inflorescence rachis, pedicels, hypanthia, and calyx lobes beset with a tardily deciduous (in part) stellate-lepidote indument. Leaves of a pair ± equal to somewhat unequal in size; blades 11-26 X 4-11.1 cm, 5-nerved with thickened poculate domatia in the axils between the midvein and each innermost primary vein abaxially, elliptic to oblong-elliptic varying to obovate, apex acute to short-acuminate, base acute to obtuse, the margin entire to undulate-serrulate, the adaxial surface glabrous, the abaxial surface essentially glabrous or sparsely covered with stellate hairs at maturity; petioles 0.7-1.7 cm long. Inflorescence a multiflowered panicle 4.5-22 cm long; flowers 5-merous on pedicels 0.5 mm long, the early- deciduous narrowly triangular bracteoles 0.75-1 x 0.5 mm. Hypanthia often nearly glabrous in fruit and bluntly 10-ribbed. Calyx tube 0.5-1 mm long, the calyx lobes rounded-triangular, 1 x 1.5-2 mm; the exterior calyx teeth bluntly triangular, 0.25 mm long, much shorter than the calyx lobes and commonly not evident on fruiting hypanthia. Petals greenish-white, glabrous adaxially but moderately to densely stellulate-puberulent abaxially, oblong to oblong-obovate, 7-8 x 3 mm. Anthers dimorphic, white or greenish-yellow, subulate; thecae alternately 5-5.5 mm long with a ventrally inclined pore and 3-3.5 mm long with a dorsally inclined pore; connective not prolonged abaxially the thecae but conspicuously thickened into an elongate ± oblong-rectangular dorso-basal swelling 1.5 mm long (on large stamens) or only slightly elevated dorso-basally for about 1.5 mm (on small stamens). Style sparsely glandular-puberulent at least basally, 7-8 mm long; stigma capitate; ovary 5-locular, 2/3 inferior, apex glabrous; berry 5-7 x 5-7 mm when dry, red-purple at maturity. Seeds ovoid-angulate, the testa ± smooth to vaguely rugulate, 0.5-0.75 mm long.
Habitat and Distribution: Low cloud forest and rain forest. 200-1000 m. Colombia and Ecuador. COSTA RICA (Gomez-Laurito 6415, CR); PANAMA (McPherson 12780, CAS).
Taxonomy and Systematics: Miconia intricata is readily seperated from congeners by the thickened poculate domatia on abaxial foliar surfaces, stellulate-lepidote indument, abaxially stellate-pubescent petals, dimorphic androecium with ventrally inclined pores on the large stamens and dorsally inclined pores on the small stamens, glandular puberulent style, and capitate stigma.
