Annuals with more or less appressed hairs of about equal length, little-branched mainly from the base; leaves first opposite and petiolate becoming alternate and sessile on stems.
Inflorescence terminal with 1-3 terminal erect scorpioid cymes with flowers loosely arranged, shortly pedicellate and partly hidden by leaf-like bracts; sepals scarcely fused basally, considerably elongating after flowering; corolla regular, cylindrical, with 5 hairy ridges between the throat of the tube and the anthers, with a ring of scales well below the anthers; stamens inserted just below the middle of the corolla tube, with anthers almost sessile; ovary 4-lobed, each with a basal ovule, with a short style inserted near the base of the ovary and with the bilobed included stigma surmounted by a sterile lobe.
Fruit with 2 lobes breaking off as hard mericarps and with a small central gynobase remaining; mericarps ovoid tapering into a terminal beak with a little developed vertical ridge, densely tuberculate, rarely rugose, with a large attachment scar at the base.
