BOTANICAL EXPLORATION IN BOLIVIA* 
Bolivia—the land-locked republic of South America—is richly 
diverse in representatives of the three natural kingdoms—in min- 
erals, in animals, and in plants, and especially in the latter. The 
wealth of its plant life as to number of kinds appears to have 
resulted, at least in part, from local differences in climate, as well 
as from striking physiographical variations and barriers. For 
olivia is a country of high stony plateaus, snow-capped moun- 
tains, deep V-shaped valleys, areas almost bordering on desert, 
tropical marshes, immense pampas, broad densely forested warm 
flat valleys, rain forests dripping with moisture from extremely 
frequent showers, dry, bromeliad-covered; hog-back mountain 
ridges and park-like areas where the herbaceous vegetation of the 
pampa (prairies) and the forests of the low-lying, flat river valleys 
come together 

a region in which the trees and shrubs form 
clumps or islands in an ocean of grass, sedge, and other low-grow- 
ing plants of the plains. 
Crossing the country in an east and west line, one passes from 
the high plateaus from 11,000-13,000 ft. in altitude, supporting a 
comparatively dense population of Aymara and Quichua Indian 
farmers and herdsmen, to the relatively uninhabited tropical wilder- 
nesses of forest and pampa that constitute part of the watershed
