Boott's figure, showing a distinct swelling in the middle of the beak (hence his specific epithet) is, according to Clarke, taken from a not fully ripe collection. In mature utricles the lower half of the beak is cylindric, somewhat swollen, the upper conic. In the specimens from Mt Kerintji the beak is scarcely swollen; they were distinguished as var. microcarya Nelmes.
Besides to C. olivacea the species is closely related to C. ischnostachya Steud. from Japan, which is easily distinguishable by the muticous glumes, but otherwise very similar.
