Stipules caducous to fugacious, ovate to oblong, 11 x 7 mm, marginally entire, glabrous, only rarely very sparingly villous, keeled; petioles (4.5–)11–35 cm, glandular and sparingly pilose atmaturity with fine sericeous villi 1–3(–3.5) mm; leaf blades oblique to transversely elliptic or ovate, (6.5–)9–16.8 x (4–)7.2–11 cm, basally cordate, apically acuminate, marginally eciliate, weakly undulate, glabrous above and sparingly pilose below, especially on major nerves; 10–12- palmatinerved. Inflorescences asymmetric, shorter than to exceeding the foliage, ca 8 or fewerflowered; peduncles (11–)16.5–38 cm, sparingly pilose with trichomes 1–3 mm; bracts caducous, broadly obovate, 17–18 x 20–22 mm, apically retuse, marginally entire, glabrous. Staminate flowers with pedicels 23–46 mm, glabrous to very sparingly pilose; sepals often coriaceous when dry, transversely elliptic, 15–21 x 23–30 mm, glabrous to sparingly glandular and pilose proximally; petals wanting; stamens very numerous, in excess of 100; filaments 0.8–3 mm, appearing free or on a slightly raised torus; anthers narrowly oblong to obovate, (1.3–)1.8–2.5 x 0.4–0.7 mm.
