There occurs every gradation from the dense tassel-spikes on 2. polystachyos 
type to the extreme form of the var. laziflora. 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.
