Names and Types in Cortaderia Stapf (Gramineae)

Summary All valid names in Cortaderia Stapf (nom. cons.) are typified and recent treatments of the genus are substantially upheld. Taxa in Section Cortaderia are more precisely defined with no major nomenclatural changes except that C. jubata (Lem.) Stapf is regarded as the valid name for plants formerly known as “C. quila (Nees) Stapf”. In Section Bifida, C. aristata and C. trianae are regarded as synonyms of C. bifida , and C. sodiroana as synonymous with C. nitida; C. minima is regarded as a synonym of C. pilosa. The new combination C. archboldii (Hitchcock) Connor and Edgar is based on Danthonia archboldii from New Guinea. The genus is gynodioecious though in some species of Section Cortaderia only female plants are found.
