Ball — Notes on Some Western Willows. 81 



Mr. Bebb thus characterizes the variety: **The beautiful 

 form described in the Botany of California differs in its more 

 conspicuously pruinose twigs, narrower leaves, grayish rather 

 than brownish silky." A specimen from Lemmon, Sierra Co., 

 Calif., has leaves densely silvery silky but does not present 

 the other varietal characters. The staminate twigs of Lem- 

 mon's 106, Fl. Calif, and Nev., S. arclica var. petraea, 

 belong to this variety of S. macrocarpa. It is hardly possi- 

 ble that Lemmon distributed these two entirely different 

 willows as the same species. 



Salix pellita Anders. 



S.pellita Anderss., Monog. Sal. 139./. 72g. 1867. 



S. chlorophylla var. pellita Anderss. in DC. Prod. 16^ ; 2U. 1868. 



S. Sitchensis yar. angustifolia Bebb in Bot. Calif. 2 : 87. 1880. 



The following notes on this little known species are pre- 

 sented mainly in order to call attention to it and perhaps in- 

 spire western collectors to secure more complete specimens 

 of it, if possible. 



Andersson described and figured a willow with narrowly 

 oblanceolate leaves, 1 to 2 inches long and 3 to 4 lines wide 

 above the middle, obtuse at the apex and attenuate at the 

 base. As types he cites specimens from Lake Winnipeg 

 (Bourgeau) and the Kooky Mts. (Lyall). A year later, in 

 the Prodromus, Andersson arranges his S.pellita as a variety 

 of JS. Morophylla. Mr. Bebb, however, considered the plant 

 more nearly related to 8. Sitchensis. He accordingly de- 

 scribed a variety angustifolia and cited specimens collected 

 by Dr. Torrey ** on a high mountain near Donner Pass," de- 

 scribing the leaves as *' acute or acuminate " instead of obtuse, 

 but otherwise agreeing with Andersson's description. He 

 also compared with thia description the Lyall specimens cited 

 by Andersson as one of the two types and expresses the result 

 thus : " Here we find the leaves 6 to 9 lines or nearly an inch 

 wide, thin and papery in texture, and only the lower spatulate 

 ones obtuse. Similar forms have been collected in Oregon 

 and British America by Hall and Macoun.*' Other more 

 recent collections all have leaves 1-2^ inches long by 5-9 

 lines wide and mostly acuminate, and any hesitation we might 

 feel in referring them to S. pellita is largely removed by this
