Abstract:
A new spleenwort species, Asplenium guodanum , was found and described from Danxia landform region in Guangdong, China. The new species has close resemblance to A. subcrenatum Ching ex S.H.Wu in morphology, but can be distinguished by having plants small, stipes and rachises not covered with fibrous scales, relatively fewer pairs of pinnae, pinnae short, pinna margin weakly biserrate, pinna apex acute and lower pinnae obviously reduced. Phylogenetic analyses, based on six plastid markers ( atpB , rbcL , rps 4 & rps4-trnS and trnL & trnL-F ) of the new species and its relatives, support a close relationship between A. guodanum and A. subcrenatum . Only one population with no more than 50 individuals were found and, therefore, it is recommended to be classified as Critically Endangered (CR) following IUCN Red List Criteria.
