 whitish midrib, at length glal>rate and dull green, beneath glaucous, imbcscent and 

 prominently rugose-veined ; the margin undulate-entire or remotely and unevenly 

 glandular-dentate ; stipules small, lanceolate, acute : fertile anient sessile, with two 

 or three small bracts at base, elongated, slenderly cylindrical, densely llowered, Avitli

15. S. glauca, Linn. Leaves elliptic-lanceolate, usually silky-villons both sides, 

 obscurely glaucous beneath, entire : aments loafy-peduncled, cylindrical, rather 

 thick, somewhat densely llowered : scales subacute or obtuse, tawny at base and 

 darker aliove, villous with long white hairs : capsules ovate-lanceolate, rather obtuse, 

 densely white-tomentose, scarcely or shortly pedicelled : pedicel e(inalling the nec- 

 tary : style produced, usually bifid ; stigmas laciniate, divaricate. — Anders, in DC.

\'ar. villosa, Anders. A diiruse shrub, 3 to 7 feet high, with short and stout 

 branches : leaves oblanceolate, acute or short acuminate, attenuate at base, 2 to 4 

 inches long, varying from soft villous to .scarcely pilose when young, at length gla- 

 brale and rigid, more or less glaucous beneath; stipules linear-lanceolate ("semicor- 

 dafe," Hook.), rather persistent: aments short-iieduncled, the i'ertilc when mature 

 sometimes very large, 2 or 3 inches long, ^ inch thick ; scales obloiig-obovate, rather 

 acute, brownish : capsules lanceolate-acuminate, tomentose, at length subglabrate, 

 shortly pedicelled : style short or scarcely produced ; stigmas bifid or entire. — Sal.

 ewan. This coniprelieiids a nuniher of forms dilfcring fioin .S'. (j/'iiim mainly in their less tomen- 

 tose and more pointed capsules, entire styles, and less <leeply cut stigmas : sulseciueiitly interposed

IG. S. Californica, Wvhh. Usually 4 to 6 feet high: leaves lanceolate to ob- 

 ovate, acute, 1^ to 3 inches long by 4 to 7 lines wide, abrujitly contracted or even 

 rounded at base, glandular serrulate, villous-tomentose when young, at length gla- 

 brato and green both sides; stipules lanceolate, acute, serrulate: aments cylin- 

 drical, densely llowered, ap|)earing with the leaves, when in llower about an inch 

 long, the fertile when in fruit lengthening to 2 inches or more ; the leaf-like bracts 

 at base closely studded on the margin with minute glands : .^scales lanceolate, acute, 

 dark, villous with long silky hairs : capsule ovate-conical, rather obtuse, grayish- 

 tomentose, 2 or 3 lines long : pedicel short but distinct, about the length of the 

 nectary : style elongated, entire ; stigmas mostly entire, erect. 



This occurs in the Sierra Nevada at lower altitudes (8,000 to 9,000 feet) than the lueeeding, 

 from JIariposa County northward {lircjtrr, Bnhmdcr, Lciniimn, (hrcnc. Mm. Auslin). Easily dis- 

 tinguished from genuine S. fffauca by the glandular-serrulate leaves, elongated entire styles, and 

 shorter erect mostly entire stigmas ; but some of the forms are not so clearly separable from the 

 \ny\vty villosa. It is nn evident transition toward S. mlcnopln/l/d (ahow!^ of the Great Lakes,
