Abstract

A vittarioid fern (Pteridaceae) distributed in Eastern Asia is described here as a new species, Haplopteris heterophylla, which has long been included in H. hainanensis. A description, illustration, distribution, ecology, and a key to congeneric relatives of the new species are provided. Obovoid-shaped paraphyses and frond dimorphism are the diagnostic characteristics of H. heterophylla. In a trnL-F matK ndhF phylogeny of 14 Asian Haplopteris species, including H. hainanensis, both morphological observations and the cpDNA phylogeny support the systematic uniqueness of H. heterophylla.
