102 FOREST TREES OF NORTH AMERICA. 



North Carolina, south near the coast to cape Canaveral and Cedar Keys, Florida. 



A small tree, 6 to 9 meters in height, with a trunk sometimes 0.15 meter in diameter; sandy soil. 



Wood heavy, hard, not strong, very close-grained, compact, susceptible of a beautiful polish; well characterized, 

 as in all the Nortji American species, by large open ducts, defining, with several rows, the rings of annual growth, 

 and connected by conspicuous branching groups of similar ducts, giving to a cross-section a beautifully reticulated 

 api>earance; medullary rays numerous, thin ; color, light brown streaked with white, the sap-wood lighter; specific 

 gravity, 0.7293; ash, 0.78.

GUM ELASTIC. SHITTIM WOOD. 



Georgia and northern Florida to Mobile bay, Alabama ; southern Illinois and southern Missouri, through 

 Arkansas to the valley of the Eio Grande, Texas (Eagle pass, Havard) [B. oblongifolia). 



An evergreen tree, sometimes 18 meters in height, with a trunk 0.90 meter in diameter, or in the Atlantic states 

 much smaller, rarely exceeding 6 meters in height; common and reaching its greatest development in the rich 

 bottom lands of eastern Texas. 



A low, depressed form of the sand-hills of the Altamaha river, Georgia, still to be rediscovered, with small 

 leaves and "edible fruit as large as a small date", is var. macrocarpa, Gray, Syn. Fl. N. America, ii', 68 {B. macrocarpa, 

 Nnttall, Sylva, iii, 37 ; 2 ed. ii, 106). 



Wood heavy, soft, weak, close-grained, very compact, the open ducts conspicuous; medullary rays numerous, 

 thin; color, light brown or yellow, the sap-wood lighter; specific gravity, 0.6544; ash, 1.23; somewhat used in 

 cabinet-making, for which it is well suited. 



A clear, very viscid gum exuded from the freshly-cut wood is sometimes used domestically.
