Infls paniculate, with terminal and axillary branches; glomerules rather small, globular, few-flowered, strongly farinose. Perianth segments 0.5–1.1 mm long, broad and imbricate, green or purplish on back with broad dorsal hyaline margin, keeled, fused for nearly 1/2 length. Fr. invested by perianth; pericarp easily removed. Seed horizontal, mostly 1.2–1.4 mm diam., circular, compressed; margin obtuse; testa glossy black, very faintly striated.
