the Andes. Clarke (loc. cit.) says:—“ Quasi U. jamaicensis forma evolutior, bracteis 
utriculisque majoribus ; praesertim distans foliis latioribus stylobasi pyramidata.” Boott 
also regarded the Mexican species as distinct from the West-Indian, and gave it a 
manuscript name, having overlooked Steudel’s.

Upwards of 800 species are enumerated, and there are probably at least 500 distinct 
ones; they are generally dispersed in Temperate and Cold regions, including the moun- 
tains within the Tropics. In North America they are especially numerous, there being 
no fewer than 150 within the limits of Gray’s ‘Manual of the Botany of the Northern 
United States ’—that is to say, in the area north of North Carolina and Tennessee and 
east of the Mississippi. And the comparatively unexplored California has already 
yielded seventy-eight species. Carex is a genus, too, that is represented in most of the 
remote oceanic islands, as St. Helena, Tristan da Cunha, Juan Fernandez, and the 
Sandwich Islands. Some of the species have a very wide range of distribution, whilst 
a large proportion are local.
