Abstract

A new species, Asplenium cyrtosorum, is described and illustrated from Pu’er, southwestern Yunnan, China. It was observed to grow in humid and shady conditions in the tropical seasonal rainforest. The new species differs from the morphologically most similar species A. trapezoideum by its shape of rhizome, length of rhizome scales, structure of laminae, pinna pairs and rachis structure.
