THE CLASSIFICATION OF POACEAE SUBFAMILY POOIDEAE

Summary Following a review of previous classifications, a revised scheme is presented for the 155 genera of Pooideae, derived via numerical analyses of original and compiled morphological and anatomical data and consideration of additional evidence. The subfamily is divided into two newly described supertribes, Poanae and Triticanae. These are further subdivided into the following tribes, all fully described: Poeae, Seslerieae, Meliceae, Aveneae and Agrostideae (in Poanae) and Triticeae, Bromeae and Brachypodieae (in Triticanae). The Aveneae are more narrowly circumscribed than is usual. The data employed in the numerical analyses are available, on microfiche, as full English descriptions.
