Epiphytic shrub, 1-2 m. Branches elongate, hanging, ramose, rather slender. Branchlets slender, terete, densely covered at the tips with fine, yellow, short hairs and much longer (2-3 mm), coarse, +-spreading, rusty, minutely gland-tipped bristles, which become dark-fuscous at their bases. Leaves ovate or long-ovate, apex +-caudate-acuminate, acute, the terminal gland small, base rounded or mostly so, very shortly contracted into the petiole, subcoriaceous or coriaceous, deep green and shining above, paler and dull beneath, very young ones laxly to subdensely covered with long, appressed, rufous bristles on both faces, mature ones glabrous above, ± persistently setose beneath especially on the midrib and in the lower part of the lamina, finally +-glabrescent or minutely blackish punctulate all over the undersurface, margin somewhat revolute in dry specimens, minutely crenulate and +-persistently setulose-ciliate, 3.5-6.5 by 1-2.4(-4) cm, triplinerved, midrib strongly impressed the entire length above, manifestly raised beneath, nerves running near the leaf-margin to the top, slightly sunken above, obscure beneath, other nerves or transverse veins higher from the midrib (4-6 pairs) minutely impressed above, or +-inconspicuous on both faces; petiole stoutish, terete, grooved, setulose, 3-5 mm. Flowers axillary, mostly solitary, sometimes in twos, occasionally also in threes in other axils of the same specimen. Pedicel rather slender, nodding, ± densely covered with ± appressed, crisped, setose, and rufous hairs initially, finally glabrescent, 3-5(-7) mm, basal bracts small. Bracteoles ovate-obtuse, glabrous dorsally, ciliolate, c. 1.5 mm. Calyx glabrous, yellow-brown, c. 4.5 mm, lobes ovate-acuminate, subacute, glandular-ciliate, 2.5-3 mm. Corolla broadly cylindric or subcampanulate, contracted at the base, glabrous, greenish, 7-8 by 3-4 mm, lobes recurved, c. 2 mm. Filaments linear, somewhat dilated above the base, glabrous, S-curved, c. 3 mm; anther-cells oblong-ovate, granular, c. 1.7 mm; tubules slender, c. 1.7 mm. Ovary glabrous, or rarely with some scattered hairs on the top; style 6 mm. Fruit ± obovoid, up to 11 by 9 mm, first green, then grey-bluish to lead-coloured, finally blue-blackish, the proper capsule green.
