Abstract
Adiantum × ailaoshanense Y.H.Yan & Y.Wang, a new natural hybrid that belongs to Pteridaceae, is described and illustrated. Molecular studies show that A. × ailaoshanense arose from a hybridization between the maternal A. sinicum and the paternal A. menglianense. In this report, the morphology, palynology, and geographic distribution of A. × ailaoshanense are documented.
