1920] SCHNEIDER, NOTES ON AMERICAN WILLOWS. VII 157 



sensu stricto is '' a very common riparian species in the calcareous districts 



from Aroostook County, Maine, and adjacent Quebec to Newfoundland.'* 



Omitting the specimens already mentioned by Fernald I can enumerate the 

 following. 



Quebec. Anticostilsland: Salt Lake, wet places August 11, 1883, J. Macoun 

 (st., No. 24564, 0.; forma incerta). Quebec District: Montmorency Falls, June 

 1, 1903, J. G, Jack (fr.; A.; this form is very much like the typical glaucophylla, the 

 branchlets are partly glabrous, partly pubescent, in the male plant the leaves are 

 more or less obovate); same locality, June 30, 1905, /. Macoun (No. 68792, O., st.; 

 ramulis etiam annotinis pilosis). Champlain County; St. Maurice River near 

 junctionofMatawin River, September 4, 1896, J. G.Jack (st.. A.). Lake St. John 

 District: Roberval, shore of Lake St. John, August 22-23, 1895, same coll. (st.; 

 A.; foliis cordatis, ramulis tomentosis, forma perro observanda). 



Geographically these last specimens seem to connect the eastern with the 

 western form. For the one w^hich is first described by Bebb as S. cordata 

 var, glaucophylla I wish to propose this new combination. 



4b, S. glaucophylloides var. glaucophylla Schneider. — S. cordata var. 

 glaucophylla Bcbb apud Babcock in The Lens, ii. 249 (Fl. Chicago Vic. 

 Suppl.) (1873); apud Patterson, Cat. PI. 111. 39 (1876). — S. Barclayi var, 

 grandifolia Bebb in Bot. Gaz. in. 21 (1878), in textu, non Andersson. — S. 

 glaucophylla Bebb apud Wheeler & Smith, Cat. Phaen. Vase. Crypt. PI. 

 Mich. 72 (1881), non Schleicher (1807), nomen nudum, nee Besser (1822) 

 nee Andersson (1851); in Rep. Nat. Hist. Northwest Univ. (1889) 23, apud 

 Watson & Coulter, Gray Man. ed. 6, 485 (1890).— Glatfelter in Rep. Miss, 

 Bot. Card, v, 57, t. 3, fig. 18 (Stud. Ven. Salix, 12) (1893). — Griggs in 

 Proc. Ohio Acad. Sci. iv. 311, t. 15 (1905). — S. cordata [subsp.] S. Bab- 

 cochii Gandoger, Fl. Eur. xxi. 166 (1890). — After having described this 

 form as a variety of S. cordata Bebb in 1878 believed that it was identical 

 with S. Barclayi, and especially with Andersson's var. grandifolia. Later, 

 in 1881, Bebb, however, made its first variety a distinct species, unfortu- 

 nately choosing for it the already used name glaucophylla. Gandoger pro- 

 posed the name S. Babcockii for apparently the very same form but his 

 name can only be regarded as of subspecific rank, otherwise I should have 

 adopted it for our species. Gandoger's description, too, is very short and 

 therefore I think it best to use Fernald's name glaucophylloides for the spe- 

 cies. As I have already shown that the main difference between Bebb's type 

 and FernalJ's eastern form consists in the somewhat longer styles and pedi- 

 cels of var. glaucophylla^ which also has larger fruiting aments and fruits 

 than S, glaucophylloides sensu stricto but this seems to be mainly due to the 

 fact that the specimens w^hich Fernald had before him did not have suflS- 

 ciently matured fruits. Those collected by Jack and enumerated above 

 approach var. glaucophylla, of which I have seen material from northern Ohio 

 (Erie County), northern Indiana (Porter County), Illinois (Cook, Lake and 

 Winnebago Counties) , the type is Bebb's No. 4, Herb. Salic, from Foun- 

 taindale, Wisconsin (Sauck and Manitiwoc Counties), Michigan (Berrien 

 and Huron Counties) and Ontario (Lambton District). 



In 1881 Bebb proposed three varieties. The first var. latifolia is nothing
