Habit: Annual, perennial herb. Stem: generally erect or ascending; internode solid to hollow. Leaf: basal and cauline, similar or dissimilar, basal rosette well developed or not; blade generally flat or rolled under; sheath glabrous or hairy; ligule short-hairy or membranous, ciliate, hairs generally > membrane, with an adjacent false ligule of longer hairs in some species Inflorescence: panicle-like, generally open; 1° branches spreading to ascending; 2° main branches simple or forked at base; spikelets many, 1--2 per node, generally stalked, on one side of axis or not, stalk tip expanded, one side concave. Spikelet: falling as 1 unit, +- compressed, generally green to +- purple; glumes generally unequal, lower generally < upper, free, clasping, upper glume +- = spikelet, membranous, +- thin; florets 2, lower sterile or staminate, lemma texture like glumes, upper floret fertile, lemma leathery to hard, firm, generally shiny, smooth to rough, margin inrolled or partly flat, tip blunt, palea +- enclosed by lemma margin.
Species In Genus: +- 440 species: tropics to warm temperate, worldwide. Etymology: (Latin: ancient name for millet) Note: Subg. Dichanthelium often recognized as distinct, monophyletic genus, as in FNANM by Freckmann; based on editorial decision, Panicum treated here to include Dichanthelium, which is phylogenetically nested in Panicum.
