H. Jochen Schenk & Wayne R. Ferren, Jr.

Annual to shrub, glabrous to hairy. Leaf: generally alternate; blade entire, cylindric to adaxially flattened or completely flattened, fleshy, generally glaucous, tip acute [obtuse to round]. Inflorescence: cyme; clusters sessile, generally in panicles of spikes; bracts leaf-like to reduced; bractlets subtending flowers 1–3, minute, membranous; flowers 1–12 per cluster. Flower: generally bisexual; calyx radial, bilateral, or asymmetric, lobes 5, generally fleshy, rounded, hooded, keeled, horned, or wing-margined; ovary ± lenticular, rounded, conic or pear-shaped, neck occasionally narrowed, stigmas 2–4(5). Fruit: enclosed in calyx. Seed: horizontal or vertical, lenticular or flat, of 2 kinds in some species.
