Nuclear–plastid discordance indicates past introgression in Epidendrum species (Laeliinae: Orchidaceae) with highly variable chromosome numbers.Here we study a challenging group of karyotypically highly variable Epidendrum spp. using phylogenetic methods to help understand how hybridization/introgression contributes to karyotype evolution. We hypothesize that species with great chromosome number variation are a result of past hybridization/introgression. Conflicting topologies in trees constructed using separate plastid and nuclear datasets...

Journal articleNew combinations and names are proposed for species formerly placed in three genera of subtribe Bletiinae. Based on the latest phylogenetic analyses of the subtribe in which species of Basiphyllaea and Hexalectris were embedded among the species of Bletia, twelve new combinations and a new name are proposed in the...
