Abstract:The dividing lines between species in the Pteris fauriei group (Pteridaceae) are questionable and the systematic positions of some species in this group remain unclear. To help comprehensively understand the phylogenetic relationships and resolve the taxonomic problems in this group a phylogenetic tree was reconstructed based on five chloroplast DNA regions (atpA, matK, rbcL, rps4-trnS & trnL-trnF) from 22 Pteris taxa. Additionally, their spore morphology and type materials were studied. Based on the molec… Show more
