In conclusion, we propose the following nomenclatural alterations. For a good classification, the genus Vulpia is to be accepted as a member of the Festuceae. Various names of Vulpia are fixed according to our present rules of nomenclature, viz. V. bromoides (L.) GRAY, V. membranacea (L.) LINK, V. geniculata (L.) LINK, V. stipoides (L.) DUM. and V. Myurus (L.) GMELIN. For Vulpia ciliata the earliest valid epithet is taken and so this widely distributed species must bear the name of V. aetnensis TINEO, while its glabrous variety is named imberbis (Vis.) HENR.. Vulpia delicatula (LAG.) DUM. var. hirsuta HENR. and Vulpia geniculata (L.) LINK var. dasyantha HENR. are described as new varieties. Among the South American species the new combinations Vulpia eriolepis (DESV.) HENR., Vulpia australis (NEES) HENR. and Vulpia muralis (KUNTH) HENR. are proposed, moreover the endemic Vulpia Teneriffae (ROTH) HENR. is mentioned. The North American species are treated in connection with the parallel variations of the European Vulpias and the following new combinations are given, viz. Vulpia octoflora (PIPER) RYDBERG, var. hirtella (PIPER) HENR., V. sciurea (NUTT.) HENR., V. arida (ELMER) HENR., V. confusa (PIPER) HENR., V. Eastwoodae (PIPER) HENR., V. Grayi (ABRAMS) HENR. and V. Tracyi (HITCHC.) HENR..
