RED MAPLE. SWAMP MAPLE. SOFT MAPLE. WATER MAPLE. 



New Brunswick, Quebec and Ontario, south of latitude 49, north and west to the Lake of the Woods, south 

 to Indian and Caloosa rivers, Florida, west to eastern Dakota, eastern Nebraska, the Indian territory, and the 

 valley of the Trinity river, Texas. 



A large tree, 20 to 30 or, exceptionally, 32 meters in height, with a trunk 0.90 to 1.50 meter in diameter ; 

 borders of streams and low, wet swamps, reaching its greatest development in the valleys of the lower Wabash 

 and Yazoo rivers. 



Wood heavy, hard, not strong, close-grained, compact, easily worked ; medullary rays numerous, obscure ; 

 color, brown, often tinged with red, the sap-wood lighter ; specific gravity, 0.6178 ; ash, 0.37 ; largely used in cabinet- 

 making, turnery, and for woodenware, gun stocks, etc. ; an accidental variety with undulating grain is highly 

 valued. 



Ink is occasionally made, domestically, by boiling the bark of this species in soft water and combining the 

 tannin with sulphate of iron ; formerly somewhat used in dyeing. 



Var. Drummondii. 

 A. Drummondii, Hooker & Arnott in Hooker, Jour. Bot. i, 199. Nuttall, Sylva, ii, 83, t. 70 ; 2 ed. ii, 30, t. 70. 



Southern Arkansas, eastern Texas, western Louisiana, and sparingly through the Gulf states to southern 

 Georgia. 



Well characterized by its obovate or truncate leaves, the base entire or slightly creuulate-toothed, densely 

 covered, as well as the petioles and young shoots, with a thick white tomentum ; fruit convergent, the wings bright 

 red, even when fully ripe. 



A large tree, in deep, wet swamps, connected with the species by numerous intermediate forms of Georgia, 

 Florida, and Alabama. 



Wood lighter than that of the species; specific gravity, 0.5459; ash, 0.34.
