Asplenium quangbinhense sp. nov. and three new records of Asplenium (Aspleniaceae) from Vietnam

Abstract

We describe a new species of Asplenium (Aspleniaceae) from Vietnam as A. quangbinhense. Morphologically, it is most similar to A. oldhamii. The new species is closely related to A. pseudopraemorsum, and a morphological comparison is presented between the two species. Three species, A. cyrtosorum, A. maguanense, and A. pseudopraemorsum, are reported as new records for Vietnam based on newly collected specimens from Quang Binh, Ha Giang, and Khanh Hoa provinces, Vietnam, respectively.
