This species occurs in montane forests in the state of Espirito Santo, Brazil, a flora noted for other endemic taxa within Melastomata- ceae. er ones with filaments 1.9-2.1 mm long, anthers 1.7-1.8 mm long, linear-oblong, arcuate, thecae 1.3-1.4 mm long; the smaller ones with filaments 1.5-1.9 mm, anthers 1.4-1.5 mm, linear-oblong, straight, thecae ca. 1.1 mm; anthers of both cycles with a narrow apical pore, ca. 0.1 mm diam.; con- nective prolonged 0.3-0.4 mm below the thecae, dorsally thickened and not appendaged, ventrally with two minute lobes, sometimes directed back- ward and appearing like dorsal appendages. Ovary 0.7-0.9 mm high, fused to the hypanthium for ?2 of its length, 3-celled, with 2-3 ovules in each cell, apex rounded, obscurely 5-lobed, papillose; style 4.5-5 mm long, filiform, apex truncate, not thick- ened. Mature fruits not seen.
