The genus Chusquea now includes species formerly classified in Dendragrostis, Rettbergia, Swallenochloa, and Neurolepis.  The genus has been organized into three subgenera, subg. Rettbergia, subg. Swallenochloa and subg. Chusquea, although molecular evidence only supports a monophyletic subg. Rettbergia.
