dangerous to Cyperologists ; many examples have the rhachis of the spikes distinctly 

 scabrous-pilose, occasionally it is quite glabrous. Further, there are two plants 

 exceedingly like C. pilosus in general aspect, viz. Juncellus Monti and Cyperus 

 procerus, Rottb., and in both of these the rhachis of spikelets is occasionally scabrous- 

 pilose.

Very like large forms of C. pilosus, but with open inflorescence, distant larger 

 spikelets, often 1 by -i in., either straw-colour or red-tinged, sometimes high-red. 

 Though very closely allied to 0. pilosus, it is seldom referred to it, because the 

 rhachis of spikes is glabrous. From its red colour it has been confounded with 

 Pycreus puncticulatus, Nees.
