Dryopteris shiakeana (Dryopteridaceae): A new fern from Danxiashan in Guangdong, China
View through CrossRef
Dryopteris shiakeana, a new species of Dryopteridaceae from Danxia landform in Danxiashan National Park, Guangdong, China, is described and illustrated. This species exhibits morphological characteristics similar to D. dehuaensis but differs in terms of dense scales on the rachis of laminae and pinnae, dissected pinnules, more prominent veinlets, reddish-brown scales on stipes, and toothed margin. Based on results of molecular phylogenetic analysis of the trnL-F sequence, our conclusion is that D. shiakeana is most closely related to D. dehuaensis.
