Shrubs, to 2.5–5 m, monoecious. Stems erect, dark brown, striate, much-branched, woody, glabrous; short shoots absent; latex watery, colorless in younger shoots, cloudy-whitish in older branches. Leaves persistent, ± evenly distributed on long shoots; stipules absent; petiole 1–5.5 cm, not stipitate-glandular; blade elliptic-ovate, obovate, lyrate, or panduriform, 7.5–15.3 × 2.9–12.5 cm, unlobed or shallowly 3-lobed, base rounded, cordate, or cuneate, margins entire (sometimes with 2–4 glands or hairs at base), apex acuminate, membranous to ± coriaceous, surfaces glabrous; venation pinnate (palmate if lobed). Inflorescences bisexual, terminal and subterminal, cymes; peduncle 5.2–21 cm; bracts 1–12 mm, margins entire, glabrous. Pedicels 2–8 mm.
