Climbing shrub, 3 m high, younger branches stellate-hirsute, soon glabrescent, older ones with longitudinal cork-ridges. Leaves subcoriaceous, oblong to lanceolate-oblong, 16-37 by 6½-9 cm, 8-12(-15)-nerved; (obtuse to) acute, usually acuminate at the apex, obtuse to acute, slightly de-current at the base; densely stellate-hirsute, soon glabrescent, with slightly sunken midrib, faintly prominent nerves, and indistinct venation above; densely stellate-hirsute, very soon glabrescent, with prominent nerves and faintly prominent to indistinct venation beneath. Petiole 8-15 mm. Inflorescences axillary (often on older defoliate branches), (1-)3-±hl0-flowered, forming a dense cluster. Pedicel 1-3 mm. Sepals 1 & 2 oval to orbicular, 2.6-3 by 2.3-2.8 mm, 4 & 5 orbicular to transverse-oval, 2.7-2.8 by 2.8-3.5 mm, sparsely stellate-hirsute outside (hairs with 4-8 subequal, up to 150 µ long branches), or glabrous (ƒ. glabra HOOGL.) outside. Corolla white, 10½-11 mm, tube 2-2¾ mm; midpetaline field 3-4 by 1½-2 mm, rather densely stellate-hirsute (hairs with 4-9 subequal, up to 200 µ long branches); lobules 4.3-6 by 2-3 mm, rather thin, with distinct venation, entire. Stamens inserted at 0.8-1.4 mm above the corolla-base; filament 1-1.3 mm long, 0.4-0.6 mm broad at the base; anther 1-1.2 mm long, 0.5-0.7 mm broad, 0.4-0.5 mm thick, broadly acute at the apex, slightly cordate at the base. Ovary 1-1.5 by 0.9-1.2 mm, glabrous; stigma conical, with 10 rather distinct ridges. Fruit unknown.
