Discussion:
The central Andean species of Calamagrostis {Deyeuxia) were studied by Weddell. 22 His paper consists of a key to species and an aphabetical list of the species with the specimens assigned to them. There are no formal descriptions. Until the type specimens have been examined the following species of Deyeuxia proposed by Weddell must remain uncertain: D. anthoxanthum (Bolivia, Weddell). D. breviaristata (Peru, Weddell). D. capitata (Bolivia, D'Orbigny 178; Weddell). D. cephalotes (Bolivia, Weddell). D. festucoides (Bolivia, Weddell). D. gracilis (Bolivia, Weddell).

D. mutica (Bolivia, D'Orbigny 182). D. nematophylla (Bolivia, Mandon 1300), D. obtusata (Bolivia, Mandon 1311). D. picta (Bolivia, Mandon 1297). D. polystachya (Peru, Weddell).
