About eighty species are known, and they are very widely spread in temperate and 
tropical countries, though quite rare in Europe and Asiatic Russia. Fournier regarded 
Vilfa of Adanson as congeneric with Sporobolus of Brown, and, being the older name, 
retained it for the Mexican species. Several of his proposed new species we have 
not seen.
