Sorghum (/ˈsɔːrɡəm/) or broomcorn is a genus of about 25 species of flowering plants in the grass family (Poaceae). Sorghum bicolor is grown as a cereal for human consumption and as animal fodder.

Evolution

Phylogeny

[edit]

The Sorghum genus is closely related to maize within the PACMAD clade of grasses, and more distantly to the cereals of the BOP clade such as wheat and barley.[2]

Taxonomy

[edit]

The Sorghum genus is in the grass family, Poaceae, in the subfamily Panicoideae, in the tribe Andropogoneae – the same as maize (Zea mays), big bluestem (Andropogon gerardi), and sugarcane (Saccharum spp.). Accepted species recorded include:[3]

Seventeen of the 25 species are native to Australia,[4][5][6] with the range of some extending to Africa, Asia, Mesoamerica, and certain islands in the Indian and Pacific Oceans.[7][8]
