High climbing liana or epiphytic bush up to 4 m, with long, pendent branches. Branchlets slender, pale rusty tomentose. Leaves +-lax, narrow-oblong to ovate, apex shortly obtusely acuminate, base broadly attenuate, truncate or cordate, with a pair of thick glands, subcoriaceous, hairy at midrib and nerves, above densely soft-hairy to tomentulose along midrib and nerves, laxly so on the intervenium beneath, with sparse, very short, appressed glandular hairs all over beneath, (3.5-)7-16 by (1-)2-5 cm, entire, 5-plinerved, midrib much impressed above, prominent beneath, nerves ± impressed above, raised beneath, reticulation lax, ± prominent beneath only; petiole tomentose, 3-5 by 1.5 mm. Racemes from the upper, partly defoliate axils, laxly 6-8(-10)-flowered, tomentulose; rachis angular, (2-)3.5-6 cm by 2-3 mm. Pedicels (1-)1.2—2 cm by c. 1.5 mm. Bracteoles (c. 5 by 2-3 mm) in the lower third to almost at base. Calyx tube cylindric, c. 3 mm, base truncate or a little apophysate, limb ± spreading, 3-4 mm, lobes broadly ovate, apiculate, 2-2.5 mm. Corolla tubular, glabrescent towards base, fleshy, base pale yellowish or greenish, turning pink towards the (sometimes lighter) lobes, (3-)3.5-4 by 0.8-1 cm (c. 4.5 by 1.3 cm fresh), lobes erect, deltoid, c. 5 mm. Stamens 13-14(-16) and 10-11(-12) mm; major stamens', filaments hirsute in upper half, c. 4 mm; cells narrow-oblong, base shortly acuminate and inflexed, (0.9-)1—1.3 cm including the narrow, divergent, c. 3 mm long tubules; connective a narrow hirsute ribbon in front connecting the cells, much broader on the back of the cells, processes slightly divergent, c. 2 mm longer than the tubules.
