Small shrubs, erect, monoecious. Indumentum of simple hairs, most parts hirsute. Stipules small, late caducous. Leaves alternate, distichous, simple; petiole reniform in transverse section, not pulvinate; blade chartaceous, eglandular, margin entire, venation pinnate, nerves looped and closed near margin, veins and veinlets reticulate, indistinct. Inflorescences axillary fascicles, with a single to few flowers of both sexes; bracts pres- ent, small, similar to stipules. Flowers 5-merous, actinomorphic; pedicels likely articulate above base, but impossible to establish correctly; sepals 5, herbaceous; petals 5; disc outside stamens. Staminate flowers: pedicel slender; petals slightly shorter than sepals; disc glands 5, bilobed for less than 1/3, lobes rounded; stamens 5, free, filaments filiform, anthers opening latrorse with lengthwise slits; pistillode of 3 free segments, apices slightly bifid. Pistillate flowers: petiole sturdier than in staminate flowers, apically somewhat widening; sepals slightly accrescent in fruit; petals much shorter than sepals; disc annular, regularly and deeply divided into 5 emarginate or erose segments; ovary 3-locular, superior, densely pilose; ovules 2 per locule; style indistinct, stigmas bifid to base, apically rounded. Fruits 3-lobed, capsular; columella slender, persistent, apically not broadened, puberulent. Seeds naked, triangular to reniform in transverse section, abaxial side convex, all sides ribbed.
