This species shows an approach to Sect. Echinochlaenae particularly in the rather small, turgid utricles with very short crura and it has frequently been mistaken for C. solandri Boott in Hook. f. The affinity is nevertheless with C. forsteri Wahl., and I regard the septate-nodulose leaves, long glumes and non-shining, subcoriaceous, rather long-beaked utricles as placing it outside the Echinochlaenae.
