Sorghum

Sorghum originated in Africa; its cultivation for grain and fodder spread throughout the tropics and subtropics of the Old World, and it was introduced to America with the slave trade. Its many cultivated forms, all derived by human selection and fully interfertile, include sweet-stemmed forms.

Sorghum (Sorghum bicolor, Poaceae) is the important tropical cereal sorghum; the cultivated plant is characterised by its large grain commonly exposed by the gaping glumes.
