Asplenium delinghaense, a new species from western part of Qilian Mountains in Qinghai-Xizang Plateau

Abstract

A new species of the genus Asplenium L. from northern Qinghai, A. delinghaense S. Q. Liang et X. C. Zhang, is described and illustrated here. This new species resembles A. iskardense Viane et Reichst., A. daghestanicum Christ, and A. neovarians Ching but differs in frond and perispore morphology. Molecular phylogenetic evidence supported the close relationship of A. delinghaense with members of the A. varians complex and the A. pekinense complex and indicated an allotetraploid origin of it.
