JOHNSTON: FLORA OF MARGARITA LSLAND. 301 
Cuba is not to be found in northern Venezuela excepting of course the 
flora common to all tropical countries. The vegetative conditions of 
these islands can be said to differ from portions only of Venezuela. 
The waste plain west of Kingston is duplicated in the plain of Mar- 
garita. The valleys and ridge of the Blue Mountains resemble those 
of the coast range above Caracas in Venezuela. The barren moun- 
tains about Santiago de Cuba are identical in appearance with range 
after range extending from Caracas to Valencia. The rolling land 
that occupies the most of Cuba with its cane fields and tobacco fields 
is similar to that of the interior of Venezuela. There still remains in 
Cuba some of the virgin forest. In fact there is considerable of it 
and it suggests that of the more nearly equatorial countries. Only in 
a limited way, however, does it begin to compare with a truly tropical 
forest. Such vegetation as is to be found along the shores of the 
Orinoco, Essequibo, and the Amazon is nowhere to be found among 
the northern islands. 
Further north than the islands of Jamaica and Cuba, in subtropical 
Florida there are naturally many changes from the tropics. Some 
districts approach in their wild luxuriance of vegetation that of coun- 
tries near the equator and on the other hand there are to be found 
some stretches barren as the desert regions of the Venezuelan islands. 
As a whole, however, the individual species making up the type of 
vegetation have changed. The difference in temperature of the 
regions sets a limit upon the distribution of the species. In passing, 
it is of interest to note that notwithstanding the great difterences in 
species, exclusive of cultivated plants there are ninety-seven different 
species occurring in both southern Florida and Margarita. 
Conclusion. 
In writing the foregoing j)ages three objects have been foremost in 
my mind : to catalogue the plants of Margarita, to describe its vegeta- 
tive conditions, and to compare its flora with that of adjacent regions. 
The catalogue of the species comprises 644 names, all of the plants 
that have been reported from Margarita. Collections, however, have 
been made only on part of the eastern end and during only a part of 
the year (March, July, August, and the first four days in September) 
thus leaving opportunity for much additional work. It is doubtful 
if this catalogue comprises much more than three fourths of the entire
