petiole sheathing entire length;

blade triangular-ovate to orbiculate, 10–40 × 10–30 cm wide, surfaces glabrous;

primary or secondary leaflets broad, serrate or shallowly cleft less than halfway to midrib, sometimes also deeply few-cleft more than halfway to midrib, ultimate segments (which are primary leaflets and their major lobes), 40–800, broadly elliptic to ovate or obovate, 0.1–20(–60) × 5–12 mm, relatively wide, larger lobes with margins usually 3-cleft and coarsely toothed or lobed, apex usually obtuse, callus tips 0–0.1 mm, terminal segment 3–15 mm;
