The form of the citation of this species should be explained. The combination is based on Andropogon barbatus Linn. (1771) which is an illegitimate name, being a later homonym of Andropogon barbatus Linn. (1759), the names being based on different plants. The epithet barbata is not, however, illegitimate in the genus Chloris and Swartz was perfectly in order in calling his plant Chloris barbata, there being no other epithet available. As the citation Chloris barbata (Linn.) Sw. is ambiguous the Code permits us to forget that Linnaeus made the illegitimate combination. Thus, Chloris barbata is regarded as a new name dating from 1797 and should be cited without acknowledgement to Linnaeus.
Chloris barbata is used as a fodder grass when young.
