Oplismenus is a small genus of annual or perennial grasses, commonly known as basketgrass,[3] found throughout the tropics, subtropics, and in some cases, temperate regions of the Americas, Africa, Asia, and Australia.

[5] The following list includes all currently recognized species of the genus Oplismenus accepted by the Catalogue of Life and World Checklist of Selected Plant Families as of March 2016, sorted alphabetically.

[11] At a later date, however, it was noted that Robert Brown had also defined the genus earlier the same year, as Orthopogon, in his work Prodromus Florae Novae Hollandiae.

In Australia, Oplismenus aemulus and O. imbecillis are recognised as separate species by the Queensland and New South Wales Herbaria, but not by the National Herbarium, which classifies them as synonyms of O.

[13] A multiple discriminant analysis published in 1978 of the characteristics used to define the species of Oplismenus worldwide found a high degree of overlap in Australia, indicating O. aemulus and O. imbecilis fell within the parameters of O. hirtellus, as did the American taxon O. setarius.
