Cenchrus

Cenchrus is a widespread genus of plants in the grass family, native to tropical and warm temperate regions of the world. Its species are native to many countries in Asia, Africa, Australia, the Americas, and various oceanic islands.

Common names include buffelgrasses, sandburs, and sand spur. Such names allude to the sharp, spine-covered burrs characterizing the inflorescences of the members of the genus. Those previously classified as Pennisetum /ˌpɛnɪˈsiːtəm/ are known commonly as fountaingrasses (fountain grasses).
