Panicum Explained

Panicum (panicgrass) is a large genus of about 450 species of Poaceae 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 tall.^{[1] [2]}

The flowers are produced in a well-developed panicle often up to in length with numerous seeds, which are long and 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.^{[3] [4] [5] [6] [7] [8]}

Australia has 29 native and 9 introduced species of Panicum.^{[9] [10] [11]}

Well-known species include P. miliaceum (proso millet) and P. virgatum (switchgrass).
