 very early deciduous : aments linear-cylindrical, borne on lateral leafy branchlets of 

 the season, often clustered at tlie extremity : scales yellowish, villous, dentate,

Var. argyrophylla, Anders. Leaves and capsules clothed with a lustrous silky 

 tomentuiu. — A', (in/ophylla, Xutt. Sylva, i. 71, t. 20. S. brachi/carpa, Xutt. 1. c. Gi) ]

 wide. — .!>'. exi(iu((, Nutt. Sylva, i. 75. 



A frequent and widely distributed species, along streams, rooting extensively in alluvial de- 

 posits, usually forming dense clumps, 3 to 15 feet bigli. Exceedingly variable, especially at tlie 

 west. From Calirornia to Texas, tbe Saskatcbewan, and tbe Nortbeiu States. 



5. S. sessilifolia, Xutt. Leaves sessile, lanceolate, entire or remotely mucro- 

 nate-serrate, esi)ccially near the very acute apex, grayish tomentose or softly villous 

 on both sides, becoming nearly smooth ; stipules acute : aments elongated-cylindri- 

 cal, densely flowered, terminating short leafy branchlets ; scales oblanceolate, villous : 

 capsules more or less tapering from an ovate base, sessile or nearly so, densely pilose 

 Avhen young : style short but distinct ; stigmas deeply bifid Avith linear lobes. —

Var. Hiiidsiana, Anders. Leaves narrowly lanceolate, about an inch and a half 

 long by 1 or 2 lines wide, very acute at each end, entire, opaquely pubescent on 

 both sides : aments short (an inch long), thick and densely flowered : capsules 

 mostly tapering to a beak. — Sal. Bor.-Am. 11. 8. Huidsiana, Benth. PI. Hartw.

The ty]iical form from tbe northern part of the State and common in Oregon ; tbe variety Hind- 

 siann in tbe Sacramento Valley {Hart wry, Bigchnv, Kcrrhernj), and Coast Ranges from Santa liosa 

 to Ukiah, Bolandcr, KeUoijy & Harford. As here understood 8. sessilifolia is distinguished from 

 S. hmgifolia mainly by the linear lobes of tbe stigma. Tbe leaves have a peculiar lanceolate out- 

 line and hoary pubescence, but vary much in wiilth, affording uo distinction between tbe more 

 northern broad-leaved type and tbe variety, which is the prevailing form in California : nor do we 

 tind in tbe shape of the capsules, or aments, any characters which are not eijually inconstant. 



S. Nevadensis, Watson (Amer. Naturalist, vii. 302), an imperfectly known species of "West- 

 ern Nevada ( JVatson, Wheeler), is a low slender bush with tbe yellowish silky-pubescent leaves 

 still smaller than in S. sessilifolia, var. Hindsiana, short slender aments (a half inch long), mostly 

 glabrous scales, and smooth slender ovaries with short thick stigmas. Perhaps a reduced form of 

 S. long if alia. 



6. S. taxifolia, HBK. A shrub, 5 to 6 feet high, with short divaricate branches 

 thickly set witli numerous subdistichous yew-like leaves, which are 3 to 6 lines 

 long, a line wide, acute, obsoletel}^ denticulate and silky-pubescent : aments oblong, 

 densely flowered, terminating the branchlets, usually clustered ; scales obovate, cili- 

 ate on the margin : capsules sessile, ovate-conical : stigmas bifitl. — Anders. Sal.

"California" (Coulter, n. 651), but the locality is luiccrtain. It is found in New Mexico 

 (n. 669, Wright), and doubtless occurs witliin our southern border, being the common sjiecies of 

 the Loncjifoliui group in Mexico.

 base, shaiply surrate, glaljrous (usually more or less silky when young), jialer and 

 reticulate-veined beneath ; stipules semilunar, dentate or small and nearly entire :
