Notes
Confused with C. sesquiflorus, from which it is distinguishable by the shape of the inflorescence, the narrow spikelets, and the narrow, brown fruits.
Although the basionym Kyllinga triceps ROTTB. is illegitimate, the correct name of this species in Cyperus is C. triceps ENDL. (1842), the synonym Kyllinga bulbosa BEAUV. (1804) already in 1842 not being transferable to Cyperus (art. 66 note 2 and art. 72 Montreal Code). ROTTBOELL’S specific epithet was nomenclaturally superfluous because the name. Scirpus glomeratus L. was cited in synonymy (art. 63), but the type of Kyllinga triceps is not that of Scirpus glomeratus, as ROTTBOELL indicated a definite type (“Dominus Konigius legit.”).
