Shrub, scandent up to 5 m. Branchlets sub-trigonous-compressed at the tips, glabrous. Leaves lax, oblong-or more rarely subovate-elliptic, apex shortly (0.5-1 cm) subabruptly acuminate, tip bluntish, base broadly attenuate into the petiole, sometimes almost rounded, basal glands ± indistinct, coriaceous, stiff, glabrous, entire or mostly minutely subserrate-crenulate, very laxly or not glandular-punctate beneath, 8-13(-15) by 3-5(-8) cm, 7(-9)-plinerved from and from above the base, midrib and nerves ± impressed above, much prominent beneath, veins transverse, +-raised beneath only, veinlets laxly reticulate, rather obscure; petiole rugose, 8-13 by 2.5-4 mm. Fascicles from foliate and defoliate axils, 5-7-flowered, subdensely short-pubescent; rachis ± absent. Pedicels 10-13 by 1 mm. Bracteoles basal. Calyx green (fresh), broadly cylindric, tube c. 3 mm, base rounded-obtuse, limb ± spreading, 2 mm, broadly 5-lobed up to halfway, or merely-apiculate. Corolla cylindric, (1.2-)1.3-1.4 cm by 5 mm, more densely hairy than calyx and pedicels or almost tomentulose, deep carmine, lobes erect, c. 3 mm. Stamens 1 and 5 mm; major stamens: filaments glabrous, 3 mm; cells oblong, base apiculate, 5-6 mm including the hardly divergent, 1.5 mm long tubules; connective laxly appressedly substrigose below, muriculate; processes +-connate, free but for their upper part, shorter than the tubules. Disk glabrous. Style thick-filiform, glabrous, c. 1.7 cm, ± exserted at full anthesis.
