Phylogenetic position of Oryzolejeunea (Lejeuneaceae, Marchantiophyta): Evidence from molecular markers and morphology

摘要: The systematic position of the small neotropical genus Oryzolejeunea (three spp.) has long been controversial. Phylogenetic analyses molecular data for present study using DNA markers (trnL, psbA, and a nuclear ribosomal internal transcribed spacer [nrITS] region) shows that is nested in Lejeunea. results not only reveal phylogenetic first time, but also challenge taxonomic value proximal hyaline papilla as key feature urgent need reassessment perimeters Lejeunea its infrageneric classification. Three new combinations, namely saccatiloba, grolleana, venezuelana, are proposed.
