Abstract

Plagiochila dubia Lindenb. & Gottsche is reduced to a synonym of the Neotropical P. panda (Sw.) Lindenb. Specimens from the Canary Islands and Madeira proved to belong to the eastern North American P. virginica A.Evans, new to Europe. Phylogenetic analyses of the internal transcribed spacer regions (ITS1-5.8S-ITS2) of nuclear ribosomal DNA of ten Plagiochila species produced for independent lineages that are well supported by all bootstrap analyses (maximum likelihood, maximum parsimony, and distance). These lineages correspond with the Plagiochila sections Arrectae, Contiguae, Cucullatae and Glaucescentes. Spruce's "Ramiflorae" and "Cauliflorae" may no longer be regarded as monophyletic units of Plagiochila.
