Information

Annual or perennial herbs or rarely subshrubs, mostly erect, often much branched. Leaves sessile, opposite, nearly always linear and mostly 1-nerved, less often penninerved or 3–5-nerved from the base; stipules with 2-several fimbriae or rarely reduced to a simple lobe. Flowers small or medium-sized, never heterostylous, in panicles, corymbs, occasionally in heads, more rarely in pairs, triads or even solitary. Calyx-lobes 4 (rarely 5), small, equal, subulate to ovate-triangular or triangular. Corolla-tube narrowly cylindrical; lobes 4 (rarely 5); throat glabrous or pilose inside. Stamens always included in the upper swollen part of the corolla-tube or only the anther-tips exserted. Ovary 2-locular; ovules numerous, immersed in fleshy peltate placentas; style always included, the stigma not divided, cylindrical, or divided into 2 filiform lobes mostly with the tips well below the base of the anthers or just reaching them. Capsule globose or ellipsoid, scarcely beaked, loculicidally splitting at the apex. Seeds numerous, angular, mostly not becoming viscid when moistened, somewhat alveolate.
