TREES OF NORTH AMERICA 



on long slender pedicels, in few-flowered fascicles on branches of the previons year, 

 from clustered obtuse buds, the staniinate and pistillate in separate clusters on the 

 same or on different trees; sepals oblong, obtuse, as long as and broader than the 

 oblong or linear petals; stamens 5-8, scarlet, with slender filaments exserted in 

 the staminate and included in the pistillate flower; ovary glabrous on a narrow 

 slightly lobed glandular disk; styles slightly united above the base, with long ex- 

 serted stigmatic lobes. Fruit ripening in the spring or early summer on drooping 

 stems 3'-4' long, scarlet, dark red or brown, with thin erect wings, convergent at 

 first, divergent at maturity, |'-1' long and \'-^' wide; seeds dark red, with a rugose 

 coat, \' long, germinating as soon as it falls to the ground. 



A tree, 80-120 high, with a tall trunk 3-4^ in diameter, upright branches 

 usually forming a rather narrow head, and branchlets green or dark red when they 

 first appear, becoming dark or bright red and lustrous at the end of their first sum- 

 mer and marked by numerous longitudinal white lenticels, and gray faintly tinged 

 with red in their second year. "Winter-buds obtuse, \' long, with thick dark red 

 outer scales, rounded on the back and ciliate on the margins, and inner scales be- 

 coming f -1' long, narrowly oblong, rounded at the apex and bright scarlet. Bark 

 of young stems and of the branches smooth and light gray, becoming on old trunks 

 \'-~^' thick, dark gray, and divided by longitudinal ridges separating on the surface 

 into large plate-like scales. "Wood very heavy, close-grained, not strong, light brown 

 often slightly tinged with red, with thick rather lighter colored sapwood; used in 

 large quantities in the manufacture of chairs and other furniture, in turnery, for 

 wooden ware and gun-stocks. 



Distribution. Borders of streams, low wet swamps, and rarely on hillsides; 

 latitude 49 north in Quebec and Ontario, southward to the Indian and Caloosa 

 rivers, Florida, and westward to western Wisconsin, western Iowa, and the valley of 

 the Trinity River, Texas; one of the most common and generally distributed trees 

 of eastern North America; most abundant in the south, especially in the valley of 

 the Mississippi River, and of its largest size in the river swamps of the lower Ohio 

 and its large tributaries; at the north often covering low wet swamps almost to the 

 exclusion of other trees. Passing into
