Shrub, scandent and ascendent to the top of high trees, sometimes epiphytic. Branchlets stoutish, sometimes compressed at apex, glabrous. Leaves lax, oblong or narrowly elliptic-lanceolate, apex shortly (c. 2 cm) acutely acuminate, base broadly attenuate, basal glands small and ± inconspicuous, coriaceous, glabrous, very laxly or practically not glandular-punctulate beneath, shallowly and rather remotely subdenticulate-crenulate (callous points early caducous), 5(-7)-plinerved from and from above the base, 11-20(-23) by 3-6(-8) cm, midrib and nerves a little impressed above, slightly raised beneath, reticulation rather obscure; petiole 8-10(-13) by 2 mm. Fascicles (3-)5-10-flowered from defoliate parts, glabrous. Pedicels 10-13 by 2-3(-4) mm. Bracteoles basal. Calyx tube cylindrical-obconical, base truncate, 4-5 by 5 mm, limb suberect, (2-)3-4 by 6-7 mm, obtusely lobed or dented up to halfway. Corolla cylindrical, fleshy or waxy, deep (crimson) red or rose red, with white or pale tips, (2.8-)3-3.5 by 0.6-0.8 cm (3.5 by 1.3-1.6 cm fresh), lobes erect, deltoid, obtuse, 4-5 mm. Stamens (12-)13-14 and (9-)10-11 mm; major stamens: filaments c. 5 mm, upper 1/3 subdensely hairy distally as is the connective in its lower part; cells elongate-oblong, base contracted, apiculate and much curved inward, (8-)9-10 mm including the divergent, 2.5-3 mm long tubules; processes subdensely to more laxly and longish substrigose, ± connate with or close, 1-3 mm longer than the tubules. Disk glabrous. Style ± slender, 3.5-4 cm, ± exserted.
