Lab. to Alberta, southw. to N. J.» Ky., and Nebr., including the northern Coastal 

 Plain. 



3a. S. lucida Muhl., var. intonsa Fernald. 



In situations similar to the preceding; rare. 



W. shore of Jennings Pond; bog, Ringwood (A. Gershoy). [Also at Long Lake, 

 Tully, Onondaga Co.] 



Newf. and Que. to w. N. Y. 



4. S. serissima (Bailey) Fernald. (S. lucida, var., no. 840 of Cayuga Fl.) Autumn 



Willow. 



Bogs and swamps, in calcareous regions ; rare. June 10-30 ; f r. Aug.-Oct. 25. 



McLean Bogs (D.\) ; Vandemark Pond (A. J. E. & L. H. MacDaniels) ; Lowery 

 Ponds (/v. M. W ., A. J. E., & L. F. Randolpli) ; Crusoe Lake (same collectors). 



Newf. to Alberta, southw. to N. J., N. Y., and the Great Lakes ; absent on the 

 Coastal Plain. A northern plant of limy regions. 



The fruit matures very late; good capsules, still unopened, have been obtained on 

 Oct. 25 when the leaves were falling. 



5. S. longifolia Muhl. Sand-bar Willow. 



Sandy shores or sandy alluvium; frequent. May 15-June 15. 



On or near the shores of Cayuga Lake: Fall Creek, below Island Fall (D.) ; Ren- 

 wick, s. of Stewart Park; n. of Esty Glen (D. !) ; Myers Point (£>.!) ; Lake Ridge 

 Point (D. !), and common for three miles northw. ; n. of Atwaters ; Lockwood Flats 

 (D.) ; Farley Point (£>.!) ; Canoga (£>.). 



E. Que. to Man., southw. in the interior to Va., Tenn., and Tex. ; generally absent 

 from N. E. and the Coastal Plain ; approaching its eastern limit in the Cayuga Lake 

 Basin. 



Often flowering again in July and August, perhaps because of insect-gall injury. 



6. S. blanda Anders. (See Bailey, Man. Cult. PL, p. 225. 1924. Anderson in 



B. C. Prod. 16 2 :212. 1868. Ascherson & Graebner, Synop. Mitteleu. Fl. 4:213. 

 1908-13. S. babylonica of Cayuga Fl., possibly.) Wisconsin Weeping Willow. 



Low grounds ; occasional. Apr. 28-May 15. 



Near Cayuga Lake: bank of Fall Creek, Renwick; Myers Point (D. !) ; Lake 

 Ridge Point ; and elsewhere. 



Cultivated, and occasionally escaped. 



Apparently both typical S. babylonica L., the weeping willow, and 5". blanda, are 

 in cultivation in the Cayuga Lake Basin. S. babylonica, however, is rare, owing to 

 its lack of hardiness. All weeping willows found escaped seem to be S. blanda, a 

 hybrid of S. babylonica and 5". fragilis. This plant is distinguished from S. babylonica 

 by its less strongly pendulous twigs, its broader leaves, its longer petioles and pedun- 

 cles, and its longer-pedicelled capsules. Both staminate and pistillate plants are 

 found. 



7. S. fragilis L. Crack Willow. 



Low grounds, shores, and moist roadsides ; common. May 5-20. 

 Especially abundant about the head of Cayuga Lake, and along upper Six Mile 

 Creek in the vicinity of Brookton ; frequent elsewhere. 

 Naturalized from Eu. Hybridizes freely with S. alba.
