Pennisetum link should remain until the species have been fully updated

The circumscription above based partly upon Chemisquay (et al.) (2013) has yet to be fully accepted by all authorities. However their evidence also confirms that the traditional subgenera and sectiones are redundant, but no work has been undertaken on their replacement.

Cenchrus is a widespread genus of plants in the grass family.[3][6] Its species are native to many countries in Asia, Africa, Australia, the Americas, and various oceanic islands.[7][8]

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.[9]

Some botanists include the genus within the related genus Pennisetum.
