The new variety is known from a single locality in southern Ecuador and differs from P. cucullifolia var. cucullifolia by the flat, not saccate leaves, somewhat smaller plant size and weaker leaf dentation. According to phylogenetic analyses of 35 nrDNA ITS1 and ITS2 sequences of Plagiochila, the two varieties of P. cucullifolia form a monophyletic lineage and are placed in a well supported clade together with five other species of Plagiochila sect. Hylacoetes: P. dimorpha Lindenb. & Gottsche var. ecuadorica (Inoue) J. Heinrichs, P. flabelliflora Steph., P. patriciae J. Heinrichs & H. Anton, P. macrostachya Lindenb. and P. turgida Herzog. Within Plagiochila, nrITS sequence variation is not concordant with morphological diversification. ITS sequences of Plagiochila cucullifolia s.str. and of P. dimorpha var. ecuadorica differ in only 23 aligned positions whereas two sequences of P. subplana Lindenb. differ in 86 aligned positions. Morphologically, P. cucullifolia s.str. and P. dimorpha var. ecuadorica differ in more than 20 characters and previously these two taxa were placed in separate genera. P. subplana phenotypes show considerable variation in leaf shape and dentation but the extremes are linked by numerous intermediates."],["dc.identifier.doi","10.1007/s00606-003-0063-5"],["dc.identifier.isi","000186956700011"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/45051"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.publisher.place","Wien"],["dc.relation.issn","0378-2697"],["dc.title","Plagiochila cucullifolia var. anomala var. nov from Ecuador, with notes on discordant molecular and morphological variation in Plagiochila"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

The historical biogeography of Plagiochilaceae is explored based on the reconstructions of the phylogeny, biogeographic patterns and diversification time estimates.

Based on the results of the molecular analyses and on morphological evidence, the tropical African species of Plagiochila are assigned to the sections Arrectae, Cucullatae, Hylacoetes, Rutilantes, Vagae, and the new sect. Africanae (P barteri, P. colorans). With the exception of Africanae, all sections possess intercontinental ranges; their centers of diversity are in the tropics. Clade and species diversity in Africa is lower than in other parts of the tropics and may reflect drought periods of the Pleistocene. Intercontinental ranges at specific level exist between tropical America and Africa whereas similarities between tropical Asia and Africa were only recovered at the sectional level. ITS sequence sets were used to test the monophyly of species with intercontinental ranges and to explore the development of the Afro-American range of P boryana. A well supported clade with accessions of P. boryana from Bolivia and Uganda is nested in the robust neotropical Hylacoetes. This topology and the low genetic distance of the different P. boryana accessions provide some evidence for long-range dispersal of R boryana eastwards across the Atlantic, originating from the Neotropics. An African origin of the Vagae clade which includes neotropical and paleotropical taxa is suggested by the clustering of accessions from the East African Islands at the base of this clade. In addition, the presented data support the hypothesis of several switches from Africa to Asia and vice versa. A derived clade within Vagae includes accessions from the African mainland and the Neotropics.
