Shrub, scrambling to 15-20 m. Branchlets obtusely subtriangular and ± densely pubescent in the youngest parts, glabrescent. Leaves elliptic-ovate to ovate-oblong, apex ± abruptly and shortly subacutely acuminate, base broadly attenuate to rounded, basal glands indistinct, coriaceous, glabrous above, subdensely pubescent at midrib and nerves beneath, laxly so on the intervenium which bears some sparse glandular points, or glabrescent, entire, 7(-9)-plinerved, nerves faintly immersed or flat above, prominent beneath, reticulation obscure, (8.5-)12—18 by (3-)4.5-7 cm; petiole initially pubescent, 9-13 by c. 2 mm. Racemes axillary, 6-10-flowered, laxly short-pubescent; rachis rather robust, 2.3 cm. Pedicels stoutish. Bracteoles in the lower third. Calyx tube subcylindric, subangular (dry), shortly and ± abruptly attenuate at base, rather swollen above, 5-6 by 3-4 mm, limb +-spreading or suberect, 2-3 by 7-8 mm, lobes very broadly ovate, subacuminate or apiculate, c. 1 mm. Corolla narrowly campanulate when fully expanded, tube reddish pink, tips white, 3-3.5 cm, c. 6 mm ø at base, 2.5-3 cm across limb, thin-fleshy, laxly pubescent outside, lobes 6-10 by 5-9 mm. Stamens 8 and 10(-11) mm; major stamens: filaments glabrous at the base, hirsutulous upwards, c. 5 mm; cells plus tubules 7-8 mm, cells connate at base into a curved appendix c. 1 mm long; tubules ear-shaped, thick, +-divergent, 2.5 mm; processes connate, hirsutulous, as long as the tubules. Disk glabrous or very sparsely and shortly hairy. Style ± slender, glabrous, not exserted.
