Between a and /3 there are intermediate forms which insensibly unite them. 

 The specimens figured approach C. arctata; but the scales and the sessile 

 perigynium, with its acute base, at once distinguish them : F. Boott.

A C oxylepide difFert culmo, foliis pedunculisque glabris (nee pilosis) ; 

 perigyniis majoribus ; squamis mucronatis ; spicis inferioribus nutantibus, 

 compositis. 



A C. formosa differt spicis inferioribus, omnino fcemineis, etc. 



A C. debili difFert perigyniis rostellatis, ore acuta bidentato nee hyalino, 

 magis turgidis; nervis validioribus ; squamis firmioribus. 



I have received (his speiies under the names of C. formosa and C. debilis. 

 The absence of the subelongate rostrum, and of the hyaline obtuse orifice, 

 separates it from C. debilis and its allies. It has hitherto escaped the notice 

 of American botanists, and its value as a species must be determined by 

 future observation : F. Boott.
