lound from New England to Missouri and the Saskatchewan and northward 
to the Arctic coast ; Oregon and Colorado. Frequent through NevaiUi and 
Utah ; 4-7,000 feet altitude. Various forms occur in the collection, more 
or less distinct ; the present with leaves 3-6' long and 6-18" wide, rounded 
or subcuneate at base, very long acuminate, finely serrulate, glabrous, glau- 
cous beneath ; stipules often large and serrate ; aments 1-3' long, on rather 
long peduncles. Becoming a small tree, 15° high and 18' in diameter, with 
usually slender virgate branchlets and rather dark-green bark. (1,095.) 
Var. Leaves li-3' long, 6-12" wide, mostly rounded at base, very 
short-acuminate, serrulate or nearly entire, occasionally subvillous beneath ; 
aments 1' long, on short peduncles. Usually about 8° high, less virgately 
branched than the last. (1,096.) 
Var. (?) Leaves still smaller, 1-2' long, 4-9" wide, mostly subacute 
at base, acute or short-acuminate at the apex, cidire or suljserrulate, 1' orh'ss 
in length, on short peduncles. 6-15° high, and occasionally 12-18' in diam- 
eter, diffusely branching, the branchlets short and divaricate; bark light yel- 
lowish-green. Of well-marked habit, and perhaps a distinct species, but 
seems to be united through the last variety with the true cordata. (1,097.) 
S. (?) Allied to S. cordata. Fertile aments (2' long) on short and 
leafy densely villous peduncles, densely flowered ; scales dark, orbicular, en- 
tire, very villous both sides, twice longer than the gland and about half as 
long as the slender pedicel (1" long;) capsule long, conical, glal)n)us; style 
rather slender; stigmas entire, suberect ; leaves 11' long, 3-5" wide, spatu- 
late, narrowed to the base, on short (1-1 i") petioles, obtuse or subacute, 
entire, densely covered with a short silky pubescence wlien young, wholly 
glabrous and rather thick when old. 6-8^ high ; stiimles obsolete. Found 
in a mountain canon near Carson City, Nevada, where it was also collected 
by Anderson (11 ;) strongly marked, but not identified. (1,098.) 
Salix glauca, L. DC. Prod. 16. 2.280. Aments leafy, peduiudcd, cyliii- 
drical, subdensely flowered; scales acutish or obtuse, tawny at l»ase and 
darker above, villous with long white hairs: caiisules ovate-lance<»latc, ratlicr 
obtuse, densely white-tomentose, scarcely or shortly pedicelled, tlu^ pedicel
