FOSSIL PLANTS FROM VERO.

ORDER RUBIALES. 
FAMILY CAPRIFOLIACEAE. 
GENUS VIBURNUM LINN. 
VIBURNUM NUDUM LINN. 
This species is represented in the Vero deposits by both drupes 
and stones. In the existing flora it is an inhabitant of swamps 
from Long Island to Florida and Louisiana. In peninsular Florida 
it is known from only the Lake region of DeSoto and Polk Counties 
and northward. Two southern varieties, augustifolium T. & G. 
and serotinum Ravenel, are sometimes distinguished by systematists, 
but I have no material of these for comparison. 
Viburnum nudum has been recorded (1) from the late Pleisto¬ 
cene of North Carolina. 
VIBURNUM CF DENTATUM LINN. 
This record is based upon drupes and stones from the Vero 
deposits. It is close to this essentially more northern existing 
species, but may not be identical with it. Viburnum dentatum is an 
inhabitant of meadows and swamps and ranges from New Bruns¬ 
wick to the upland of Georgia. It does not occur in Florida at the 
present time. 
ORDER VALERIANALES. 
FAMILY AMBROSIACEAE. 
GENUS XANTHIUM LINN. 
XANTHIUM SP. 
Two small fruits characteristically those of Xanthium and 
probably Xanthium glabratum (D. C.) Britton were found in the 
Vero deposits. Some years ago I collected a fruit of Xanthium 
from the late Pleistocene along the Chattahoochee River, the occur¬ 
rence of which I did not publish as I was not positive that it had not 
been accidentally mixed with the Pleistocene material.
