vrrietles of C. ancqis. In different states and situations the 
leaves of this species are found from an inch and a half to a 
line in width ; and the form of the fruit and scales is also quite

anceps, sometimes occurs with broad leaves ; and in this va- 
riety (C. oligocarpo- var. latifolia, Gray, Gram. ^^ Cyp. part 2. 
no. 178) the leaves are usually glaucous, the spikes more 
densely flowered, and the fruit usually somewhat larger. The 
figure of Schkuhr represents the plant with fewer flowers than 
is usual, but is obviously intended to represent this species.
