Subshrubs [perennial herbs]. Stems usually erect, hairy [glabrate], not viscid. Leaves distalmost sometimes subsessile; stipules usually persistent, filiform, subulate, or minute; blade broadly ovate to ovate-triangular [narrowly triangular], unlobed, base cordate, margins entire [crenate-dentate], surfaces usually stellate-hairy [sometimes glabrate]. Inflorescences terminal panicles or racemes; involucel absent. Flowers: calyx not accrescent, not inflated, shorter than mature fruits, lobes not ribbed, triangular; corolla usually yellowish, sometimes white, rotate; staminal column exserted; style 3–6-branched; stigmas capitate. Fruits schizocarps, erect, not inflated, obovoid, not indurate; mericarps 3–6, 2-celled, apex bulbous-apiculate, proximal cell indehiscent, distal cell dehiscent. Seeds (1–)3 per mericarp, lower cell 1-seeded, upper cell usually 2-seeded, hairy, proximal seed relatively more densely hairy. x = 7.
