Abstract

A new fern species, Hypodematium eglandulosum, is described and illustrated from southern China and Southeast Asia, and a new combination is made, H. chrysolepis, from Africa. Hypodematium eglandulosum is distinguished from its similar species by plants eglandular, leaves 3-pinnatifid, and stipes upward sparsely covered with acicular hairs or nearly glabrous. The description and photographs of H. eglandulosum are provided. Aspidium chrysolepis is currently treated as a synonym of H. crenatum, but it should be recognized.
