SALICACE^. Salix. 



anient ronndish-otovate and ciicullate, 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, flilcate, 3 or 4 inches long, 

 9. lines broad near the roundish base : approaching S. nicp-a. 



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

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



From San Diego Count}' {Palmer) to Sacramento Valley and Sierra County (Lcmvwn) ; distin- 

 guislied from iS. ni(jra by tlie broad coriaceous leaves, glossy above and glaucous beneath, and by 

 the dentate scales. The ambiguous vaiiety angustifolia was collected by Ftcv. 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." — Z)/-. G. 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 

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

 stigmas bifid. — PI. Hartw. 336. S. Hoffmanniana, Hook. & Arn, Bot. Beechey,

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

 small : scales of the fiexuose staminate anient deeply and irregularly glandular- 

 dentate : " branchlets red and leaves darker." — S. argiita, 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. — jS. lancifolia, Anders. Sal. Monogr. 34, fig. 23. S. lucida,

Var. Fendleriana, Bebb. Staminate aments thick, densely floAvered, on shorter 

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

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

 Nevada {Mrs. R. M. Austin, Lemmmi) ; also New Mexico (Fencller) 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 Viranches 

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

 scribes the "summit" of the tree as "tufted and spreading." Very near ^. ZitaVZrt (especially 

 the var. Frndleriana), but the leaves are I'ather 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 supi)osed 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 

 eacli species respectively. 



§ 2. Stamens 2 : scales pallid, soviewhat deeidtious : aments borne on sJiort lat- 

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

 denticulate or entire. Shnd>s. Species exceedinrjly variable and appar- 

 ently ptassing 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
