Biogeography and the origin of extant species of the schismatoglottis nervosa complex (araceae : schismatoglottideae)

This study presents the phylogeny and biogeography of the Schismatoglottis Nervosa complex (Araceae: Schismatoglottideae) based on the nuclear ITS region and chloroplast regions (matK, trnL-F, psbA-trnH). The aim is to provide evidence for divergence and biogeographical implications of the comple...
