1920] SCHNEIDER, NOtES ON AMERICAN WILLOWS. X 75 



Taller, 1-7 m. high; twigs Wack or green and black, without bluish bloom, 

 the older branches often banded with gray and black; leaves oblong, soon 

 glabrous above, very glaucous beneath, the hairs on the lower surface be- 

 coming more or less brown. The coast form; Shawnigan; Victoria; New 

 Westminster." As I already stated it is partly the typical S. macrocarpa 

 of Nuttall. The leaves sometimes are somewhat denticulate, the lower 

 surface often becomes almost glabrous and their texture is firmer than 

 of those of the type. The branchlets of the year are not unfrequently 

 rather orange-colored (see for example Suskdorf's specimens from Falcon 

 Valley, September 7, 1896). Of var. meleina I have seen specimens from 

 British Columbia (Vancouver Island and New Westminster District), 

 Washington (Stevens, King, Mason, Thurston, Pierce, West Klickitat 

 and probably Clarke Counties where Nuttall seems to have collected the 

 type of S. macrocarpa on the banks of the Columbia), Montana (Flathead 

 and Missoula Counties) and northwestern Oregon (Columbia and 



Marion Counties). 



The typical S. Geyeriana is known to me from the following states and 

 counties: northwestern Idaho (Shoshone and Latah Counties), Montana 

 (Deer Lodge, Gallatin and Madison Counties), Oregon (Grant, Jackson, 

 Crook, Wallowa, and Klamath Counties), Wyoming (Yellowstone Park, 

 Albany and Sheridan Counties), eastern Nebraska (Scotts Bluff County), 

 Colorado (Jackson, Larimer Lake, Gunnison, Mineral, and Grant Coun- 

 ties) and Utah (Sevier County; a specimen of H.D. Langille, from Uinta 

 Mountains, 1902, [No. 125, m., f.; A.; "5-7 feet high"] is uncertain, the 



Arizona 



Apache Counties). 



S. S. Lemmomi Bebb apud Watson, Bot. Cal. ii. 88 (1879) ; in Bot. Gaz. 

 XVI. 106 (1891) — Jepson, Fl. Cal. 343 (1909), pro parte. — Rydberg. Fl. 

 Rocky Mts. 196 (1917), pro parte. — When Bebb described this species 

 he proposed three varieties basing his descriptions mainly on specimens 



Lemmon 



The first is var. 



melanolepis characterized by pitch-black and slightly or not at all hairy 

 scales. Bebb cites no type but there is one in his herbarium in the Field 

 Museum (No, 7794) consisting of male and female specimens. Here, too, 

 are type specimens of the second var. macrosiachya, and the third var. 

 sphaerostachya, and two sheets which represent the typical form. All these 

 specimens came from Sierra Valley in Sierra County, except those of var. 

 sphaerostachya which are only marked "Sierra Nevada." 



The type of S. Lemmonii (No. 7800 in Herb. Bebb) has unripe fruits 

 and young leaves, and well agrees with that of var. melanolepis. The dif- 

 ferences mentioned above are of no importance, because we can observe 

 a change in the pubescence of the bracts not only in the aments of the same 

 twig but even in the bracts of the same ament. Only in the male syntype 

 of var. melanolepis (sheet 7799 in C.) the glabrousness of the bracts is a 

 little more conspicuous. The size of the aments and the more or less ful-
