Cycloloma

Herbs, annual, polygamo-monoecious, villose or tomentulose, becoming glabrous at maturity. Stems erect, much branched, especially in inflorescence, not jointed, not armed, not fleshy. Leaves alternate, petiolate or almost sessile; blade oblong-ovate, oblong, or lanceolate, base cuneate, margins sinuate-dentate, apex acute or mucronate.

Flowers bisexual or pistillate; perianth segments 5, connate to above middle; stamens 5; stigmas 3. Fruiting structure: connate perianth segments enclosing utricle, at maturity forming horizontal, membranous, circular wing; pericarp membranous, free. Seeds horizontal, ovate-lenticular or globose-lenticular; seed coat black, smooth or indistinctly sculptured; embryo annular, perisperm copious. x = 9.^[3] [more]
