 BLACK MANGROVE. BLACK TREE. BLACK WOOD. 



Florida coast, Saint Augustine to the southern keys, and from Cedar Keys to cape Sable; deltas of the 

 Mississippi river ; through the West Indies to Brazil. 



A tree 6 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 O.CO 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 (Rhizoplibra), 

 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.

PIGEON WOOD. BEEF WOOD. CORK WOOD. PORK WOOD. 



Semi-tropical Florida, cape Canaveral to the southern keys; through the West Indies. 



A tree 9 to 15 meters in height, with a trunk 0.25 to 0.45 meter in diameter; saline shores and beaches, 

 reaching its greatest development in Florida on Elliott's and Old Ehodes Keys. 



Wood heavy, rather soft, weak, coarse-grained, compact, containing numerous large open ducts; layers of 

 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. acultata, Linnaeus, of the same region, although attaining a considerable size, 

 cannot be properly considered arborescent.

PIGEON PLUM. 



Semi-tropical Florida, cape Canaveral to the southern keys, and from cape Eomano to cape Sable. 



A tree 15 to 18 meters in height, with a trunk 0.30 to 0.60 meter in diameter; one of the largest and most 

 common trees of the region. 



Wood very heavy, exceedingly hard, strong, brittle, very close-grained, inclined to check in drying, containing 

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

 brown tinged with red, the sap-wood lighter; specific gravity, 0.9S35; ash, 5.03; valuable and somewhat used for 

 cabinet- making. 



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

 and other animals.
