Shrub, whether or not epiphytic, 0.5 m. Branches elongate, divergent, slender. Branchlets densely and rather patently rufous-setulose (c. 1.5 mm) in the young, gradually glabrescent in the older parts. Leaves elliptic to ovate, apex broad-acuminate, the terminal gland rather thick and protruding, base broadly attenuate to rounded, young ones laxly clothed with longish ± patent setulose hairs on both faces and the margin, glabrescent with age, the marginal bristles ± permanent, the undersurface finally dotted with blackish points, margin superficially denticulate, (0.9-)1.2-1.7(-1.9) by (0.5-)0.6-1 cm, midrib slightly impressed above, other nervation obscure; petiole setulose, 1-2 mm. Flowers 1—2(-3) in the upper axils. Pedicels slender, shortly patent-setulose, (6-)8—10 mm, basal bracts several, very small. Bracteoles broad-ovate, subglandular-ciliolate, 1 mm. Calyx 2.5 mm, contracted at the base, glabrous, lobes broad-ovate, 1.4 mm, margin very shortly glandular-muriculate and ciliolate. Corolla broadly campanulate-urceolate, slightly constricted at the mouth, glabrous, white, c. 4 mm long and wide, lobes short, recurved. Filaments linear, inflexed, glabrous, 1.5 mm; anthers triangular-ovate, granular, c. 1 mm including the very short tubules. Ovary glabrous; style 2 mm. Fruit blackish blue, c. 5 mm ø.
