A new species, Camptandra kampucheaensis Nob.Tanaka & Funak. (Zingiberaceae), from Bokor National Park, southern Cambodia, is described and illustrated. Molecular phylogenetic analysis using the nuclear ribosomal internal transcribed spacer (ITS) region was carried out to determine the phylogenetic position of the new species among allied taxa. The new species is monophyletic with other three species of Camptandra and branched off at the basal position in the clade. Camptandra kampucheaensis is similar to C. ovata Ridl. in their small size and solitary stem with ovate leaves, but well distinguished by the broader leaves with more significantly cordate base, pinkish corolla lobes, and slightly pinkish labellum with yellow patch in basal center. Detailed description, line drawings, and color plates of habitat and habit are provided. A key to all species of Camptandra is also provided.
