THE BROTH PELICAN. 
Florida of a greater height than twenty-five or thirty feet, and its average 
height is not above fifteen feet. The land mangrove, of which I have seen 
only a few, the finest of which were on Key West, is a tall tree, much larger 
and better shaped than the other, with narrower leaves and shorter fruits.
