Erect andromonoecious or androdioecious perennial, up to 0.3 m tall, 0.5 m wide, with ascending flowering branches spreading from a central tuft of basal leaves. Leaves dimorphic, elliptic to narrowly elliptic, the base attenuate, main veins abaxially raised and adaxially sunken, surface on both sides puberulent to glabrescent, grey-green to red-green, concolorous, the margin dentate in upper third and entire lower down; basal leaves with petiole (10-)40-60(-160) mm long, pubescent to glabrous along entire length, lamina (15-)0-40(-50) mm long, (10-)15-20(-30) mm wide; margin occasionally entire or with two to five acuminate teeth in upper third; apex acuminate; upper leaves (on flowering shoots) petiolate or more often sessile, petiole 5-10(-40) mm long, pubescent to glabrous along entire length, lamina (10-)15-20(-45) mm long, (2-)4-10(-17) mm wide; margin entire or occasionally with two to three acuminate teeth in upper third; apex acuminate. Inflorescence with a central single sessile bisexual umbellule mostly surrounded by many lateral, rayed male umbellules (or sometimes with many rayed male umbellules only); rarely with many rayed bisexual umbellules without a central bisexual umbellule. Male umbellules 3-5 mm long, with a single male flower each. Bisexual umbellules with a single flower each; borne in axils of flowering shoots; bracts of male umbellules two or rarely three, up to 1.5 mm long, not foliaceous, glabrous; bracts of central bisexual umbellule paired, 1-2 mm long, 1-1.5 mm wide, lanceolate, glabrous. Flowers with cream coloured petals; petals abaxially pubescent. Fruit widely elliptic, 4-5 mm long, 3-4 mm wide in commissural view, bulging of commissure not prominent; ribs prominent, the surface between ribs smooth, glabrous; stylopodium not prominent.
