Leaves alternate; stipules sometimes persistent, filiform, 0.5 cm long, glabrous; petioles short, ca 4.0 cm long, terete, glabrous, petiole attachment to lamina basal, nonpeltate; lamina membranaceous, abaxial surface wax pattern reticulate; venation camptodromous, veins glabrous; lamina 3 lobed; median lobes linear or narrowly lanceolate, to 9.0 cm long, apex acuminate; lowest lobes more or less similar to median lobes in outline, slightly nonsymmetric. Inflorescence monoecious, terminal, short racemes, simple or a cluster of 2-4 racemes arising from a common base, ca 3.0 cm long, all parts glabrous; bracteoles semifoliaceous, ca 1.5 cm long, ca 0.3 cm wide, margins laciniate; bractlets semifoliaceous, ca 1.0 cm long, 0.2 cm wide, margins laciniate. Pistillate flowers restricted to the base of the inflorescence, pedicels less than 1.0 cm long, tepal 0.9 cm long, cleft to base into 5 lobes, ovary subglobose, the trifid stigma sparsely lobed and lobulate. Staminate buds conical; flowers small; tepal 0.9 cm long, cleft 1/3 way down into 5 lobes; stamens 10, in 2 whorls of 5 each.
