Low erect bushy shrub, quite glabrous. Nodes unilacunar and one-trace. Leaves petiolate, estipulate, alternate, small, simple, crenate or serrate, with rounded to acute teeth, pinnately veined with conspicuous secondary veins terminating near the leaf margin. Inflorescences erect bracteate racemes. Flowers essentially 4-merous, small, regular, hermaphrodite; sepals 4, essentially free, imbricate, persistent; petals 4, free, spreading, spatulate, clawed, slightly imbricate(?), caducous; stamens 4 or 8, borne apparently in a single whorl, although one or more members of the whorl may be missing; filaments free, filiform; anthers elliptic-oblong, basifixed, latrorse; carpels 4(5), fusiform, prominently stipitate, erect, free for most of their length; stigmas subsessile, small, lobed; ovules bitegmic, crassinucellate, numerous, borne on branched submarginal placentae. Fruits multifollicles; follicles erect, stipitate, coriaceous, many-seeded; seeds very small, obovoid-subulate, testa membranous, slightly prolonged at each end, with narrow wings extended along their entire length and parallel ridges on the surface; embryo minute, at the base of fleshy copious endosperm.
