Shrub, 1-3 m, rarely treelet up to 5 m, generally a large epiphyte. Branches greyish brownish corticate, striate. Branchlets terete, pale brown, with shedding thin bark in the older parts, angular and papillose-puberulous in the young shoots. Leaves ovate-elliptic, apex rather abruptly or shortly acutely subcaudate-acuminate, not rarely somewhat falcate, the terminal gland small, base attenuate into the petiole or sometimes nearly rounded, rather fleshy-subcoriaceous to coriaceous, glabrous and ± shining above, rather dull and laxly mostly ± obscurely punctulate beneath, finally completely glabrous, margin sometimes slightly revolute, entire, (4-)5-8 by (1.5-)2.5-4 cm, 5-7-plinerved from and somewhat from above the base, midrib impressed above, manifestly prominent beneath, 2-3 outer pairs of nerves curved-ascending to the top of the lamina, slightly impressed above, +-raised beneath, other nerves less distinct, shorter and pinnate from the upper part of the midrib; petiole stoutish, grooved, 4—6(-8) mm. Flowers axillary, mostly 3—4(—6) per fascicle, occasionally only 2 or 1 in other axils of the same specimen. Pedicels stoutish, rather densely clothed with fine, yellowish hairs and some short thicker, +-crisped, brownish ones, at anthesis (3-)4-6 mm, glabrescent and a little accrescent in fruit, basal bracts few, small. Bracteoles ovate, obtuse, keeled, short-hairy along the midrib or glabrescent, ciliate and shortly glandular-fimbriate, 1.5-2 mm. Calyx c. 4 mm, glabrous, rugulose, lobes ovate, glandular-ciliolate and-fimbriate, c. 2.5 mm. Corolla campanulate, green to whitish green or cream, glabrous, 6 mm, lobes ovate, obtuse, reflexed, 1.5-2 mm. Filaments linear, slightly dilated towards the base, glabrous, curved in the upper half, 3 mm; anther-cells ovate-oblong, granular, 1.5 mm; tubules slender, 1.5 mm. Ovary mostly laxly hairy on top, sometimes glabrous; style 4-5 mm. Fruit 4-5 mm ø, blue-blackish.
