Panicum arctum (Panicum arctum)
Description
Panicum (panicgrass) is a large genus of about 450 species of grasses native throughout the tropical regions of the world, with a few species extending into the northern temperate zone. They are often large, annual or perennial grasses, growing to 1-3 m tall. The flowers are produced in a well-developed panicle often up to 60 cm in length with numerous seeds, which are 1-6 mm long and 1-2 mm 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. Australia has 29 native and 9 introduced species of Panicum. Well-known Panicum species include proso millet and switchgrass.
