164 JOURNAL OF THE ARNOLD ARBORETUM [vol. i 



woodiae seems to liave distinctly darker bracts. Tlie serration sometimes 

 suggests that of S. adenophylla. 



I have seen wliat I call typical S, Easiivoodiae from the following counties 

 in California (north to south) : Lasson, Plumas, Sierra Nevada, Placer, 

 Eldorado, Tuolumne, ]\Iariposa, Mono, Fresno and Tulare. This Willow 

 inhabits the Sierra Nevada between about 2300 and 3500 m. alt. It is also 

 known to me from Washoe County, Nevada, and there are forms from the 

 Siskiyou Mts. in Jackson County, southern Oregon, which may belong to 

 this species. Unfortunately I have not yet seen male specimens. Speci- 

 mens from eastern Oregon, Wallowa ]\Its., which have been referred to it, 

 are more closely related to S. commidata (sec var. pubcrula, above). 



There Is a form which corresponds to var. sericea of that species. I wish 



to propose for it the name S. Eastwoodiae f. callicoma, nov. forma: a typo 



non nisi difTcrre videtur foliis (saltem junioribus) utrinque et ramulis densis- 

 sime sericeo-lanuginosis. For the type may be taken a specimen collected 

 by G. B. Grant, Tulare County, Sequoia Nat. Park, Marble Fork of the 

 Kaweah River, about 2500 m., July 15, 1902 (f., fr.; St. [sheet 83180]). I 

 have seen quite a number of forms which connect this very hairy form with 

 the typical form. It occurs also in Nevada, Ormsby County, about Mar- 

 lette Lake, 24(50 m., July 10, 1902, C. F, Baker (No. 1299, fr., ni.; G., M., 

 W.). 



In S. commidata and in S. Barclayi I have observed besides the typical 

 form with glabrous ovaries one with more or less hairy pistils. In S. East- 

 woodiae the type has pul)escent ovaries and fruits but there is also a form 

 with more or less glabresccnt ovaries and almost or wholly glabrous fruits. 

 I have already mentioned Brewer's No. 2788 with glabrous capsules. There 

 are more specimens like this, but all need furtlier observation. In a later 

 article I shall describe a new species which looks somewhat like a variety of 

 S. Eastwoodiae with glabrous ovaries but, in my opinion, belongs to a differ- 

 ent section.
