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