in shape. — The specimens have lanceolate or oblanceolate leaves, 1-3' long, 

 3-6" wide, light-green, short silky-pubescent or subglabrous, especially above ; 

 young aments h-1' long, becoming 1-2' in length at maturity. 2-3° high, 

 diffusely branched, with short and stout branchlets. On the shores of sub- 

 alpine lakes in the East Humboldt Mountains, Nevada, and in the Wahsatch ; 

 9,000 feet altitude. June-August. (1,099.) 



Salix arctica, R. Br. DC. Prodr. 16. 2. 286. Aments lateral and subter- 

 minal upon long strict leafy peduncles, erect, rather thick and densely flowered ; 

 scales obovate, obtuse, pale or dark-colored, pilose ; capsule conic from an 

 ovate base, tomentose or glabrous, the short pedicel rather exceeding the 

 gland ; style middle-sized, becoming brown, with divaricately parted stig- 

 mas ; leaves obovate, oval or spatulate-lanceolate, entire or obsoletely and re- 

 motely serrulate, at length smooth, glaucous beneath. — In various forms, 

 from latitude 64° to Behring Strait, the Arctic Sea, and Greenland ; Una- 

 laska ; Labrador ; Rocky Mountains of Colorado. In the Uintas, at 

 11-12,000 feet altitude, in broad clumps, a foot in height. Perhaps nearest 

 Var. Brownei, And., but not according closely with any of the described 

 varieties ; leaves 1-14' long, 4-9" broad, oblong or rather oblong-lanceolate, 

 usually broadest above the middle, rounded at base, acute or short-acumi- 

 nate, slightly woolly or silky-pubescent, becoming glabrous, glaucous be- 

 neath, remotely serrulate or entire ; sterile aments small, 2-4" long, the 

 fertile J-l' long, on villous, not very long peduncles ; scales dark and villous ; 

 capsules short-pedicelled, tomentose. (1,100.) 



Salix phlebophylla. And. DC Prodr. 16. 2. 290. Aments upon 

 lateral leafy branchlets or terminal, cylindric, rather short, densely flowered, 

 erect ; scales round-ovate, dark, pilose or. bearded with long white hairs ; 

 capsules ovate-conic, brownish, puberulent, sessile; gland exceeding the 

 base of the capsule ; style elongated, brown, as well as the divaricately 

 parted stigmas ; leaves oblong-obovate, very shortly acuminate or subobtuse, 

 coriaceous, persistent, entire, colored alike on both sides, almost always with 

 scattered white hairs beneath and upon the margins, otherwise perfectly 

 glabrous and shining, the parallel nerves strongly prominent on both sides. — 

 In Northwestern Arctic America and Unalaska ; also collected by Lyall on 

 the summits of the Cascade Mountains. Uintas; 10-11,000 feet altitude ; 

 August. Very dwarf and slender, the leafy decumbent stems scarcely an 

 inch in length ; leaves 2^5" long and 1" wide ; aments 3-4" long. (1,101.)
