(Cyperaceae), a new species of Carexsect.Cryptostachyae in limestone regions of Guangdong, China, is described and illustrated. Both morphological observation and molecular analysis revealed that the new species was similar to , but differs in having inflorescence with 4-8 spikes, ovoid or nearly globose, 3-8 mm long, utricles (2.5-3.5 mm long) and nutlets (2-2.2 mm long) shorter, style base thickened, leaves narrower, 3-6 mm wide and culms 8-25 cm tall. Scanning electron micromorphology of utricles and nutlets of the new species and the related species are provided.
