JOHNSTON: FLORA OF MARGARITA ISLAND. 177 
After the citation of Venezuelan plants, I have given reference to 
the occurrence of the species in Porto Rico as found in Urban’s Flora 
portoricensis. These citations are based upon Professor Urban’s 
comparison of my plants with his so that the distribution of the plants 
in these two localities is made certain. The last note after a species 
is in regard to its general distribution. 
The arrangement of the families is as in Engler and Prantl’s Pflan- 
zenfamilien, and the genera and species are alphabetically arranged 
in their respective groups. 
While it is to be regretted that each species could not be subjected 
to the critical examination of a specialist it is to be hoped that this list 
in connection with the distributed plants may be of value in future 
work upon the flora of Venezuela.
