Leaf blades ovate to broadly lanceolate in outline, sometimes hastate, about 2.4-7.5 x 1.8-7 cm, petioles about nearly absent to 4.5 cm long. Both the upper and lower leaf blade surfaces clothed in curved hairs, each hair with a swollen base. Similar hairs are also present on the petioles and twigs.

Male flowers: borne in fascicles or racemes of 3-10(-15) flowers; flowers about 4-5 mm diam; calyx tube (hypanthium) about 3 mm long, lobes linear about 0.8-1.4 mm long; corolla lobes ovate about 3.8-4.2 mm long; stamens 3, two stamens with 2-locular anthers and one stamen with a unilocular anther; stamens inserted about middle of hypanthium tube. Female flowers: 1 or 2, rarely 3 or 4 per axil; pedicels to 2 mm; ovary ca. 3 mm long, hairy; ovules few; base of the style surrounded by an annular disk.
