Ampelodesmos is a monospecific, xerophytic genus that is native to the Mediterranean. It is now established in California. It is somewhat similar in overall shape to Cortaderia, but differs in its membranous ligules, drooping and somewhat one-sided panicles, and deeply ribbed leaves.
Ampelodesmos was initially included in the Stipeae by Decker (1964), who was struck by the similarity of its leaf cross sections to those of some members of the Stipeae. Other characteristics it shares with at least some members of the Stipeae are its 3 lodicules, relatively small chromosomes, pubescent ovaries, and deeply ribbed leaves. Molecular data also support its inclusion in the Stipeae (Soreng and Davis 1998; Hsiao et al. 1999; Jacobs et al. 2006). It is anomalous within the Stipeae in having more than one floret per spikelet and prolonged rachillas.
