Abstract: Caobangia A. R. Smith & X. C. Zhang, originally described from northern Vietnam, was recently collected from southwestern Guangxi, China. The genus is similar to Lepidogrammitis, Lepisorus and Lem-maphyllum, but differs by having long-creeping filiform rhizomes with clathrate rhizome scales, monomorphic to subdimorphic simple blades with dense acicular scales. Caobangia is a monotypic genus, with only one species, namely C. squamata A. R. Smith & X. C. Zhang, which at present is only found in Caobang Province of northern Vietnam and southwestern Guangxi of China. According to the original literature and specimens from Guangxi, the characteristics of this monotypic genus are described, and habitat photos of C. squamata are also provided.

Key words: Caobangia A. R. Smith & X. C. Zhang, Caobangia squamata A. R. Smith & X. C. Zhang, China, newly recorded genus, Polypodiaceae
