Aira cristata Linnaeus, Species Plantarum 1: 63. 1753.

"Habitat in Angliae, Galliae, Helvetiae siccioribus." RCN: 589.

Basionym of: Poa cristata (L.) L. (1767) .

Lectotype (Humphries in Cafferty & al. in Taxon 49: 244. 2000): Herb. A. van Royen No. 913.62-99 (L) . - Epitype (Humphries in Cafferty & al. in Taxon 49: 244. 2000): France. Jura, Bas-Bugey, Montagny de Ste Claire sur Brioguier, 400-500m, 3 Jun 1929, Briquet 6737 (BM-000576281; iso- G).

Current name: Koeleria macrantha (Ledeb.) Schult. ( Poaceae).

Note: This name has been discussed by a number of authors including Domin (in Biblioth. Bot. 65: 142. 1907) and Arnow (in Syst. Bot. 19: 7. 1994). Koeleria cristata Pers. (1805) is not a combination based on A. cristata L. and this epithet is therefore pre-occupied in Koeleria . Humphries’ typification confirms the identity of A. cristata, and its correct name in Koeleria is K. macrantha (Ledeb.) Schult.
