g4 SALICACE^E. Salix. 



ament roundish-obovate and cucullate, in the female narrower and truncate, with 

 2 to 4 irregular teeth at the apex : capsule conical from a thick base, acute, glabrous : 

 pedicel 3 or 4 times the length of the nectary : style obsolete or short ; stigmas 

 emarginate. 



Var. angustifolia. Leaves narrower, taper-pointed, falcate, 3 or 4 inches long, 

 9 lines broad near the roundish .base : approaching S. nigra. 



Var. congesta. Aments short, densely flowered, scarcely exceeding the ample 

 leaves of the peduncle : capsules globose-conical, shortly pedicelled. 



From San Diego County (Palmer) to Sacramento Valley and Sierra County (Lcminon) distin- 

 guished from S, nigra by the broad coriaceous leaves, glossy above and glaucous beneath, and by 

 the dentate scales. The ambiguous variety angustifolia was collected by Rev. E. L. Greene near 

 Yreka. "An erect pyramidal tree, 15 to 50 feet high, growing on bottom lands near streams : 

 trunk straight, a foot or two in diameter, with fissured dark brown bark." Dr. C. L. Anderson. 



* * Petioles glandular. 



3. S. lasiandra, Benth. Leaves lanceolate, taper-pointed, attenuate or round- 

 ish at base, smooth, paler or glaucous beneath, margin closely and sharply serrate ; 

 petioles glandular at the upper end ; stipules semilunar, glandular-serrate, often 

 large and conspicuous, sometimes small or deciduous : aments leafy-peduncled : 

 scales yellowish, thin, more or less dentate, hairy at base or in the female 

 ament somewhat glabrous : stamens 5 or more : capsules lanceolate : style short ; 

 stigmas bifid. PI. Hartw. 336. S. Hojfmanniana, Hook. & Am. Bot. Beechey,

Var. typica. Leaves linear-lanceolate, acuminate, attenuate at base : stipules 

 small : scales of the flexuose staminate ament deeply and irregularly glandular- 

 dentate : " branchlets red and leaves darker." S. arguta, var. lasiandra, Anders. 1. c. 



Var. lancifolia, Bebb. Leaves tapering regularly from near the roundish or sub- 

 cordate base to a long attenuate point (sometimes 5 to 7 inches long and 2 inches 

 wide) ; petioles very glandular ; stipules on vigorous young shoots large and glandu- 

 lar-serrate, on flowering branches small and deciduous : scales in the female ament 

 linear, acute, somewhat glabrous, in the male broader, hirsute, and dentate as in the 

 narrow-leaved forms. S. lancifolia, Anders. Sal. Monogr. 34, fig. 23. S. lucida, 

 var. macrophylla, Anders, in DC. -Prodr. xvi 2 . 205, ex descr. 



Var. Fendlei'iana, Bebb. Staminate aments thick, densely flowered, on shorter 

 and less leafy peduncles : leaves more coriaceous in texture and green both sides.

Sacramento Valley and northward to British Columbia ; the var. Fendleriana in the Sierra 

 Nevada (Mrs. R. M. Austin, Lemmori) ; also New Mexico (Fendler) and Colorado. A tree 20 

 to 60 feet high, growing along streams: "bark fissured, grayish brown on the trunks of old 

 trees ; branchlets shining yellow, drooping : the somewhat straggling stem sends up long branches 

 bearing large leaves near the top, making the tree top-heavy." Dr. Anderson. Nuttall de- 

 scribes the "summit" of the tree as "tufted and spreading." Very near S. lucida (especially 

 the var. FendJeriana), but the leaves are rather thinner in texture, usually narrower, the male as 

 well as the female aments leafy-peduncled, and the scales distinctly dentate. The Pacific Coast 

 forms have been subdivided into two supposed species, based upon minute characters drawn from 

 the length of the pedicels, form of the scales, capsules, stipules, etc., but these prove to be very 

 unreliable and do not always correspond with each other nor with the form of leaf assigned to 

 each species respectively. 



2. Stamens 2 : scales pallid, somewhat deciduous : aments borne on short lat- 

 eral leafy branches, often clustered: leaves linear to lanceolate, remotely 

 denticulate or entire. Shrubs. Species exceedingly variable and appar- 

 ently passing into each other. 



4. S. longifolia, Muhl. Leaves varying from linear to lanceolate, long-acumi- 

 nate, tapering at base, sessile or nearly so, 3 or 4 inches long and 1 to 6 (usually 2
