Herbs or subshrubs, annual or perennial, glabrous. Leaves sessile, fleshy, cross sections of fresh leaves ± uniformly green when seen at 10× magnification. Inflorescences glomes, each glome in axis of one leaflike bract; bracteoles subtending glomes without marginal hairs. Flowers bisexual or sometimes unisexual; perianth irregular or zygomorphic, sometimes appearing ± actinomorphic, globose to wider than long; perianth segments connate proximally (sometimes forming fleshy disk), succulent or thin, abaxially flat or rounded, sometimes distally hooded, and/or with abaxial appendages (transverse proximal wings, keels, and/or distal horns), apex obtuse to acute; ovary ovoid, transversely ellipsoid, or pyriform; stigmas 2–5, inserted on attenuated apex of ovary, linear, smooth or papillate. Seeds horizontal, strongly dimorphic in some species and individuals; lenticular with seed coat black, blackish brown, or blackish red, shiny, and easily removable from pericarp; or flat to discoid and coiled with seed coat brown, dull, and not easily removed from pericarp.
Distribution
Worldwide.
Discussion
Species ca. 40 (6 in the flora).
Selected References
None.
