1920] SCHNEIDER, NOTES ON AMERICAN WILLOWS. VII 161 



forms. Its synonym is as follows: S. commutata var. sericea Bebb in Bot. 

 Gaz. XIII. Ill (1888). — S. glauca var. villosa Howell. Fl. N.W. Am. 621 

 (1902), pro parte, non Andersson. — S. commutata var. mixta Piper in Contr. 

 U.S. Nat. Herb. xi. 216 (Fl. Wash.) (1916). I refer to it the following 

 specimens. 



Washington. Mason County: Olympic Mts., August 11, 1890, C, V. Piper 

 (m., f., Pu.); same loc, July 19, 1897, J, B, Flett (No. 112, m.; Pu.). Chelan 

 County: Skagit Pass. Horseshoe Basin, August 24, 1892, Lake & Hull (No. 765, 

 m,. f.; Pu.). Pierce County: Mt. Rainier, 2000 m., August, 1889, £ .C. Smith & 

 C. V, Piper (m., fr.; M.; forma quasi ad var. typicam transiens). 



Oregon. Hood River County: moraines near the snowline on the north side 

 of Mt. Hood, July 29, 1886, Th. Howell (m., f., fr,; C, N.; type; stylis apice bifidis, 

 stigmatibus parvis, pedicellis ad 1.5 mm. longis interdum pilosis bracteam sub- 

 superantibus); August 1, 1886, same coll., (m., f., fr.; G.; stylis integris, pedicellis 

 plus minusve aequilongis glabris, glandulam ad 3-plo superantibus); near or on the 

 glaciers, July, 1884, L. F. Henderson (m., fr.; G.); south west slope of Mt, Hood, 

 at timber line. 200-2300 m., 1896, C. iV. Merriam (m.; W.). 



Bebb's second variety is var. denudata which came from the same locality 

 as the typical S. commutata. This is a very uncertain form, Bebb's de- 

 scription being very insufficient : " Young leaves smooth or nearly so, more 

 or less distinctly serrulate.'' Cusick collected it on the Eagle Creek Mead- 

 ows in Oregon but, unfortunately, there is no type sheet preserved in 

 Bebb's herbarium. Ball, who looked over the commutata material in herb, 

 Bebb in 1908 marked sheet 7750 (Cusick's No. 1304 c) as " type materia 

 of var. denudata Bebb." Bebb has drawn a figure of a fruit on this sheet 

 and written in pencil: " Capsule glabrous ped. pilose short scarcely exceed- 

 ing the gland, leaves elliptical or ovate-lanceolate tomentose both sides," 

 which is quite correct, but it does not agree with the original diagnosis 

 given above. There are some more sheets of Cusick's collection. Of these 

 the sheet witli the Nos. 7741-42 may be regarded as the type material. It 

 consists of 2 branchlets with rather old female flowers and two with male 

 flowers which are marked No. 9G8 (in pencil by a hand unknown to me) and 

 two sterile branchlets which are numbered 981 (this is No. 7741, C). I 

 should refer the flowering specimens to S. Barclayi (like Cusick's No. 2302 

 of 1899, Higher Wallow Mts., of which the young leaves are more or less 

 bluish gray beneath; this number Is named var. denudata In Herb. C), but 

 the leaves remain underneath rather pale green if the leaves of some elder 

 branchlets (No. 981) represent the same form. The ovaries are partly 

 rather copiously pubescent, but partly glabrous, as it is not unfrequently 

 the case in S. Barclayi. The dark color of the bracts, too, points to >S. 

 Barclayi, but much better material is needed to decide the question whether 

 this is a good variety of S. Barclayi or S, commutata. Bebb's note in pencil 

 on sheet 7741-42 runs as follows: " Capsule glabrous (abnormally slightly 

 hairy), style short, stigmas mostly entire, scale dark, thinly villous, leaves 

 ovate-lanceolate glabrous, green both sides, the earliest finely glandular 

 serrulate, mature leaves less conspicuously so, stipules ovate, pointed 

 glandular-serrulate, buds large smooth." I regard this sheet as Bebb's 

 type. Ball's type (sheet 7750) I am unable to distinguish from typical
