A COLLECTION OF PLANTS FROM THE VICINITY OF 
LA GUAIRA, VENEZUELA. 
By J. It. JomNsron. 
INTRODUCTORY NOTES. 
In 1900 Capt. Wirt Robinson, of the United States Army, and Dr. 
M. W. Lyon, jr., of the United States National Museum, spent six 
weeks in the vicinity of La Guaira collecting for the most part speci- 
mens of animals. Incidentally they were able to gather together 
about 60 plants, which were sent to the United States National Her- 
barium, and most of which have recently been turned over to me for 
identification. 
The plants in the following list were all collected near La Guaira, 
Macuto, and San Julian. Macuto is about 5 kilometers to the east of 
La Guaira on the coast, and San Julian is about 12 kilometers to the 
east of La Guaira and nearly 1§ kilometers from the shore. For a 
description of the topography, temperature, and rainfall of this 
region one should refer to “An annotated list of mammals collected 
in the vicinity of La Guaira, Venezuela,” by Robinson and Lyon, in 
the Proceedings of the National Museum." 
It is sufficient to say in this connection that the shore rises abruptly 
to an altitude of over 2,500.meters immediately above La Guaira, and 
that the exposed hills are barren or covered with a dry shrubbery, 
the low valleys with palms and other trees, and the high gorges with 
a great luxuriance of tropical vegetation. The very narrow littoral 
plain is clothed with a typical desert vegetation of cacti, crotons, 
lantanas, ete. 
In addition to the list of Robinson and Lyon’s plants it has 
seemed well worth while to include under each species notes of 
its further occurrence in Venezuela as determined from other collec- 
tions. It should be noted that the plants of Fendler, of Birschel, and 
of Rusby and Squires here cited as occurring in Venezuela have not 
before been published upon, at least so far as I can ascertain. The 
notes made here are obtained from reference to the plants at the 
United States National Herbarium and at the Gray Herbarium of 
Harvard University.
