Description Annual or perennial, usually pubescent, erect or decumbent herbs. Leaves opposite, usually sessile or subsessile, exstipulate, often viscid. Flowers few in dichasial cymes, white. Sepals 5, rarely 4, not connate. Petals as many as the sepals, rarely absent, emarginate or 2-cleft, white. Stamens 10, occasionally less; anthers versatile, 2-celled, longitudinally dehiscent; filaments flattened, scarcely if at all connate to form an obscurely glandular annulus. Ovary superior; carpels 5, rarely fewer, with as many distinct styles, the many campylotropous ovules arising from basal or central placentae. Capsule often arcuate (hence the generic name), dehiscing longitudinally into as many deeply emarginate valves as there are styles; seeds numerous, cochleate, usually tuberculate, estrophiolate, the embryo coiled about the perisperm.
