Notes
There occurs every gradation from the dense tassel-spikes of P. polystachyos type to the extreme form of the var. laxiflora. The favourite name for this abundant species with authors appears to be Cyperus polystachyos, Rottb., which I have doubtfully referred (in Hook. f. Fl. Brit. Ind. vi. 616) to Cyperus subcapitatus, C. B. Clarke. Whatever C. polystachyos, Rottb. may have been, as it had a trifid style, it was not our present species nor any Pycreus .
