Affinis C. toetoe Zotov sed dispositione pilorum foliorum et majore florum magnitudine differt. Gramen gynodioicum perenne habitu dense caespitosum, innovationibus robustissimis culmis altissimisque. Vaginae foliorum inferiorum pilosae virides subter cera alba, superiorum glabrae eburneae. Laminae latae flexibiles, costis medianis dense tomcntosis, marginibus et apicibus scabridae. Paniculae longae, erectae vel nutantes, Glumae longae, lemmatis aristis longiores. Antherae florum hermaphroditorum antheris florum femineorum longiores, gynoecia florum hermaphroditorum gynoeciis florum femineorum breviora.
