The genus Cyperus appears to be widely dispersed 
over the world, no countries, however, are sorich in this 
genus asthe United States, the West India islands, and 
the continent of India; there are also 9 species in Barbary, 
mest of them common to Europe. The C. favescens, C. 
virens and the C. fuseus, are the only species in the north 
of Europe; of which, the first is also common to the Unit- 
ed States. Northern Asia and Australia appear to afford 
no species of this genus, though there are many species 
at the Cape of Good Hope. Upon the whole, it appears 
that the principal habitat of the Cyperus is North America 
and India within the tropics. A considerable number of 
species are common to very distant regions.
