444 CYPERACEA, 
1. CYPERUS. 
Cyperus, Linn. Gen. Plant. n. 66; Benth. et Hook. Gen. Plant. iii. p. 1043. 
Of this large and widely spread genus upwards of 700 species have been proposed ; 
but it is probable that a large number of them have been described under two or more 
names from different countries; and Bentham and Hooker estimate that there are not 
more than 400 really distinct ones. The Mexican species are in need of a thorough 
revision and comparison with those from other parts of the world.
