 Mississippi river ; through the West Indies to Brazil. 



A tree G to 9 meters in height, with a trunk 0.25 to 0.30 meter in diameter, or, exceptionally, 20 to 23 meters in 

 height, with a trunk 0.60 meter in diameter; north of Mosquito inlet reduced to a low shrub; common along 

 saline shores and swamps, throwing up many leafless, corky stems, and forming, with the red mangrove {Bhisophora), 

 impenetrable thickets, or, more rarely, scattered and round-headed; reaching its greatest development in the United 

 States on the west coast of Florida, north of cape Sable. 



Wood very heavy, hard, rather coarse-grained, compact, the eccentric layers of annual growth marked by 

 several rows of large open ducts; medullary rays numerous, thin; color, dark brown or nearly black, the sap- 

 wood brown; specific gravity, 0.9138; ash, 2.51.

 annual growth and medullary rays hardly distinguishable; color, yellow tinged with brown, the sap-wood darker; 

 specific gravity, 0.6529; ash, 7.62; probably of little value. 



Note. The semi-prostrate and vine-like trunks of P. aculeaia, Llunsens, of the same region, althongh attaining a considerable size, 

 cannot be properly considered arborescent.

 few small, scattered, oi)en ducts; layers of annual growth and numerous medullary rays obscure; color, rich dark 

 brown tinged with red, the sap-wood lighter; specific gravity, 0.9835; ash, 5.03; valuable and somewhat used for 

 cabinet-making. 



The edible and abundant grape-like fruit, ripenmg in February and March, is eagerly devoured by raccoons
