General/Distribution: A genus of 22 species in tropical and warm temperate regions, mainly in Africa and America; 5 species occur in Pakistan.
Comment/Acknowledgements: Cenchrus is distinguished from Pennisetum by the transformation of the involucral bristles into a spiny cup. The tendency is barely recognisable in Cenchrus ciliaris, whose membership of the genus is justified by its intergradation with Cenchrus pennisetiformis.
