dangerous to Oyperologists ; many examples have the rhaehis of the sju^es distinctly 

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

 exceedingly like C. pilosas in general aspect, viz. Juncellus Monti and Oyperus 

 procerus, Eottb., and in both of these the rhaehis of spikelets is occasionally scabrous,

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

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

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

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

 Pyereus pnnctieulatus, Nees.
