ON THE VEGETATION OF TROPICAL AMERICA.* 
Euc. WARMING. 
Twice I have been able to visit tropical America. The first 
time was about thirty years ago, when as a young student I stayed 
for over three years in Brazil, almost the whole time in Lagoa 
Santa, with the paleontologist, Dr. P.W. Lund. The second time 
was in the winter of 1891-2, when I traveled for some months 
in the Antilles and Venezuela. Having been requested to deliver 
an address at one of the general meetings of naturalists I have 
thought that perhaps it would be of interest to those present to 
hear some statements about the vegetation of tropical America, 
and some attempts to explain its deviation from our own northern 
one. Most likely these statements will in some degree cor- 
respond with the facts about other tropical countries, but as it is 
best to keep to what we are in some degree acquainted with, I 
must say that where in the following I am speaking of tropical 
facts, it is especially the American ones that I have in mind. 
The interest of the northern botanist newly arrived in the 
tropics is immediately awakened by the variety of species, 
genera, and even families of which he has never seen living 
representatives. Of course this is not peculiar to the tropics, 
for into whatever non-tropical or even alpine region he goes, 
he will find a wide difference from the vegetation of his native
