Description

Scandent shrub; branchlets tomentose, older branches glabrescent. Petiole slender, 1-1.5 cm long, yellowishtomentose; blades chartaceous, ovate to elliptic-oblong, 6-17 x 3-7 cm, margins entire, sometimes minutely revolute, apex acute and acuminate-cuspidate, somewhat deflexed, base acute to rounded or subcordate, glabrous except the slightly pilose veins above, densely yellowish pilose or tomentose especially on veins beneath; primary vein slightly prominent above, strongly prominent beneath, secondary veins 7-9 on each side, like the reticulation well visible and slightly prominent above, strongly prominent beneath. Inflorescences axillary or supra-axillary simple or double racemes, rhachis flattened, densely yellowish pilose, especially when young, at one side with two rows of alternating glomerules of (1-)2-5 flowers. Flowers small, subsessile when young, pedicels to 2 mm long at anthesis; calyx about 1 mm high, lobes acute, deltoid, petals 5, oblong to lanceolate, 2-2.5 x 0.7-1 mm, agglutinated at base; stamens 5, filaments 1.5-2 mm long, anthers ca. 0.7 mm long, dorsifixed; ovary ovoid, densely pilose, ca. 1 mm long, style elongating to ca. 0.5 mm long, stigma glabrous, discoid. Fruit ovoid, thin fleshed, pink-crimson when ripe (ex Fanshawe).
