Key to Ctenium

A genus of about 20-22 species, of tropical and subtropical Africa and the Americas. Oulo et al. (2024) studied the phylogenetic relationships with African Kampochloa and also found that American and African species of Ctenium form two separate but closely related clades, only recently (< 5 million YA) diverged from one another.
