Athyrium sessilipinnum: A new lady fern (Athyriaceae) from southern China

Abstract

A new species of Athyrium from southern China is described and illustrated as Athyrium sessilipinnum. Morphological comparisons among this new species and similar ones (e.g., A. arisanense, A. gedeanum, A. epirachis, and A. otophorum) are provided. Molecular evidence reveals a sister relationship between the new species and A. arisanense. The most distinctive characters of A. sessilipinnum are the sessile, non-pinnatifid and non-shortened pinnae.
