Habitat and Range. In varying .soils and situations ; wet 

 woods, low, damp fields, river valleys, along roadsides, occa- 

 sional upon uplands and hill slopes. 



From Montreal west to Georgian bay. 



Maine, southward, rare ; New Hampshire, eastern limit 

 in the Connecticut valley, where it ranges farther north than 

 any other of our hickories, reaching Well's river (Jessup) ; 

 Vermont, occasional west of the Green mountains and in 

 the southern Connecticut valley ; Massachusetts, rather 

 common, abundant in the vicinity of Boston ; Rhode Island 

 and Connecticut, common. 



South to Florida, ascending 3500 feet in Virginia; west to 

 Minnesota, Nebraska, Kansas, Indian territory, and Texas. 



Habit. A tall, slender tree, 50-75 feet high and 1 foot-2 

 feet in diameter at the ground, reaching greater dimensions 

 southward. The trunk, tapering gradually to the point of 

 branching, develops a capacious, spreading head, usually 

 widest near the top, with lively green, finely cut foliage of 

 great beauty, turning to a rich orange in autumn. Easily 

 recognized in winter by its flat, yellowish buds.
