A natural order of glabrous or pubescent herbs or shrubs, mostly American, a few being African, and one broadly dispersed over Asia, but not indigenous. Flowers regular, hermaphrodite, axillary, solitary or few, sessile or pedunculate, rarely racemose; calyx tubular, five-cleft, deciduous, the lobes imbricated; petals five, inserted at the throat of the calyx, clawed, membranous, twisted, deciduous, naked or with a scale at the tip of the claw; stamens five, very rarely hypogynous; filaments free, flat-subulate; anthers oblong; ovary free, one-celled; styles three, filiform; peduncles free or connate with the petioles, occasionally jointed, often bibracteolate. Capsule one-celled. Leaves alternate, petiolate, simple or pinnatifid, often argutely serrated, frequently biglandular at base; stipules small or wanting. The order embraces three genera--Erblichia, Turnera, and Wormskioldia--and about seventy-six species.
