Leaf blades 5–13 cm long, 6.0–17.5 cm wide, triangular to almost reniform, shallowly 5- or 7-lobed or sometimes unlobed, with 7 or 9 main veins from the attachment point of the petiole, the upper surface glabrous or sparsely to densely hairy, the undersurface sparsely to densely hairy, the base shallowly cordate, rounded to bluntly pointed at the tip or the tips of the lobes, usually with an abrupt minute sharp point at the very tip. Inflorescences 3–8 cm long. Sepals 1–3 mm long. Petals 4–12. Stamens 12–36, the anthers 4-locular. Pistils 2–4. Fruits 9–15 mm long, more or less globose, bluish black, the endocarp discoid, with a transversely ridged crest around the rim, both sides concave. 2n=52. May–June.
