Morphology Reproductive morphology Inflorescences Bracts
Glumes ½ imbricate, oblong-ovate, 2.7 – 3 × c. 1.5 mm Involucral bracts 2 – 3; lowest erect as if continuation of the stem; upper one often inconspicuous
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets strongly compressed, 5 – 20 × 2 – 2.5 mm

Note
The best characters to differentiate Cyperus scariosus from C. pertenuis are its erect lowest involucral bract, thereby pushing the inflorescence to one side of the culm, and the flatter, broader spikelets. It seems Clarke (1909) utilised the above mentioned specimen for the illustration in which these characters are clearly drawn. Brown (1810) did not select any type for Cyperus scariosus. Therefore one of his original collections from Australia (Brown 5893) is selected here as the lectotype. This specimen is in good condition and adequately displays the features of this species.
