GENERAL NOTES. 
BOTANY. 
Tue Grasses OF Mexico.—M. Eugéne Fournier has raised the 
number of species of grasses from eighty-eight, as reported in 
Kunth’s Synopsis, to 638. He finds that sixteen species extend 
from the shores of the ocean to the elevated plateaux. He also 
finds, as he had previously done in regard to the ferns, that many 
species oe on both slopes of the Cordilleras. Out of 162 
species common to Mexico and other regions, only two grow in 
California, East the Rocky Mountains, Texas has thirty-two 
species, one grows in the prairie region, and the other fifty-nine 
United States pollens are almost confined to Florida, Georgia and | 
South Carolina, scarcely any occurring in Louisiana, Mississippi, 
or Alabama. The cause of this peculiar distribution may 
found in the direction a certain winds, especially the whirlwinds _
