Characteristics

Scandent or scrambling shrub, ascending to 20 m, with long trailing branches, or epiphytic. Branchlets angular, slender, glabrous. Leaves lax, elliptic-oblong, apex for c. 1 cm subacutely acuminate, base broadly attenuate, basal glands ± distinct, subcoriaceous, glabrous, laxly appressedly glandular-muriculate or-punctate beneath, regularly subserrate-crenulate, the crena-tion 2-3 mm spaced, c. 0.3 mm long, 6.5-9.5 by 2.5-3.5 cm, 5-7-plinerved from and from a little above the base, midrib and nerves slightly impressed above, prominent beneath, reticulation lax, ± faintly raised especially beneath; petiole (6-)7-9 by 1-1.5 mm. Fascicles from foliate and defoliate axils, (3-)4-7(-9)-flowered, subdensely and shortly pubescent at pedicels and calyces, slightly longer and more densely so at the corolla; rachis ± absent. Perulae pubescent dorsally, up to 5 by 3 mm, early caducous. Pedicels stout, gradually thickened distally, 10-13 mm, in fr. 15 mm. Calyx tube cylindric, c. 3 by 3 mm, green, base obtuse or subtruncate, limb erecto-patent, 2.5-3 mm, 5-lobed almost halfway, lobes depressed-ovate and apiculate. Corolla subcylindric, 1.8-2 cm long, 4-5 mm ø at base, 6-8 mm across the mouth, very dark, blackish red, whitish at the lobes, rarely paler, densely red-hairy on the tube, white-hairy at the lobes outside, lobes obtuse, c. 4 mm. Stamens 8 and 6.5 mm; major stamens: filaments densely shortly substrigose distally as is the connective, c. 3 mm; cells narrow-oblong, c. 7 mm including the tubules, hairy in front between cells and at acute base; tubules c. 2 mm, ± divergent; processes free, ± equalling the tubules. Disk laxly very shortly hairy at the inner margin. Style slender, glabrous, 2-2.5 cm, much exserted at anthesis. Fruit subglobose, truncate, with a calycine rim of 5 short teeth, laxly pubescent, 7-8 mm ø (dry).
