Panicum, commonly called panicgrass, is a large genus of about 250 species of grasses mostly native to tropical regions.
Description
The flowers are produced in a well-developed panicle often up to 60 cm (24 in) in length with numerous seeds, which are 1–6 mm (0.04–0.24 in) long and 1–2 mm (0.04–0.08 in) broad. The fruits are developed from a two-flowered spikelet. Only the upper floret of each spikelet is fertile; the lower floret is sterile or staminate. Both glumes are present and well developed.
