1241,'^ m.; St.)- — Ventura County: Ventura, along beach, April 17, 1916, A. 

 Eastwood (no. 5034, m., 5035, f. ; Cal.). — Santa Barbara County: Santa Ynez 

 River, alt. 600 m., May 1894, C. Franccschi (m.; A.; quasi ad var. Hindsianam 

 transiens). — Tulare County: shores of Kern River, Peppermint Valley, alt. 

 1440m., July 16, 1895, W. R. Dudley (no. 779, m.; St.); gravelly bars of 

 Kaweah River at Three Rivers, July 20, 1900, W. R. Dudley (no. 2703, St.; 

 St.); Three Rivers, near Brittons, June 15, 1902, W. R. Dudley (m., fr.; St.; 

 all these forms of Tulare County come near var. Hindsiana; the fruiting 

 aments of the last specimen measure up to 6:1 cm.). See also Brewer's no. 

 544 mentioned in the preceding note. 



Specimens from Kern County, Bakersfield, September 28, 1910, E. M. 

 McGregor (no. 13, m.; St.), look much like S. exigua and need further observa- 

 tion. There is a specimen from Santa Barbara County, Ojai, Cliff Glen, March 

 15, f., April 3, 1896, m., F. W. Hubby (no. 56; Cor.), of which the leaves much 

 resemble 5. taxifolia, but those of the more vigorous shoots seem to become 

 larger. The female flowers have 2 glands, and the stigmas are rather short but 

 agree with those of some forms I have referred to var. leucodendroides. I am 

 not quite sure about this specimen, but I strongly suspect that it is a form of 

 var. leucodendroides grown in a very arid position. It is similar to Parish's nos. 

 4591, 4592 already mentioned.

 Nuttall says: ''This species lines the immediate border of the 

 Oregon [Columbia] a little below its confluence with the Wahlamet" 



'No. 1243 of the same collector from Red Hill, near Upland, April 28, 1917, 

 apparently represents the female form of the same willow. Mr. Johnston kindly 

 sent me the following note regarding this number: "1243 from Cucamonga Canyon. 

 Small colonies of this willow occur in scattered localities in the lower canyons of the 

 San Antonio Mountains; although common in the valley it is uncommon in the 

 mountains. 1 243 came from one of these isolated colonies, and from absolute knowl- 

 edge I know that no other colony of this or any other Longifoliae occurs within 

 3 miles. The associated Salix spp. were S. laevigata and S. lasiolepis. Nothing like 

 5. exigua occurs for miles. This is by no possibility a hybrid." Judging by the 

 stigmas this form is more closely related to S. exigua than to S. sessilifolia. The 

 forms of this part of S. CaHfornia need a special study, and it is almost impossible to 

 express a definite opinion on them as long as S. Parishiana and S. exigua and its 

 varieties are not yet properly understood.
