 cending ramifications; stamens twice as long as petals; 

 sepals upright in fr. : follicles ciliate at the inner suture.

 narrow, oblong to oblanceolate, acute, usually regularly 

 simply serrate, 1K-2H in. long : fls. white, in leafy 

 pyramidal tomentulose panicles, the lower spreading 

 ramifications much longer than their supporting lvs.; 

 stamens white, usually as long as petals: follicles quite 

 glabrous. June-Aug. From N. Y. west to the Rocky Mts., 

 south to Ga. and Miss. Also known as S. salicifolia. 



45. latifdlia, Borkh. (S. salicifdlia, var. latifblia, Ait.

 quite glabrous, broadly pyramidal, with spreading and 

 elongated ramifications ; stamens longer than petals. 

 June-Aug. Newfoundland and Canada to N. C. Em. 

 2:485. B.B. 2:196. — This and the preceding species have 

 been referred by most American botanists to S. salicifo- 

 lia, S. alba is chiefly found west, 5. latifolia east of 

 and in the Alleghanies.
