NEOTYPIFICATION OF THE NAME GEUM-PYRENAICUM (ROSACEAE)

There is no extant original material for Geum pyrenaicum Mill., a name sometimes attributed to Willdenow. Although the name has often been m isapplied to the hybrid G. montanum x G. rivale by Central European au thors in the past, and may have been so used by both Miller and Willde now, its universal use for a Pyrenean-Cantabrian endemic for 150 years makes it advisable to fix that application by designation of an appro priate neotype.
