gg SALICACE.E. Salix. 



Santa Barbara {^frs. Ehuood Cooper); Santa Cruz {Anderson), Bear Valley {Bolrnider), and ex- 

 tending northward to Alaska. A most beantilul and distinct species, remarkable tor the silvery 

 under-surlace of the leaves. Leaves about an incii broad above the middle : fruiting aments 3 

 or 4 inches lont?: style and pedicel of about equal length. Nuttall calls this " Velvet Willow." 

 The variety «wf/i<s//7o/(«, collected on a "high mountain near Donner Pass" by Dr. Torrcy, 1865, 

 accords essentially" (excepting the pointed "leaves) with the description of ,S'. chhroplu/lhi, var. 

 pel/itn, Anders., though wlien compared with Dr. Lyall's specimens from the Kocky Mountains, 

 cited by the author, the discrepancy is greater; here we find the leaves 6 to 9 lines or nearly an inch 

 wide, thin and papery in texture, and only the lower spatulate ones obtuse. Similar forms have 

 been' collected in Oregon and British America by //«// and il/ncoim, ajipearing like 6". Sitchensis 

 modified by growing in the shade. Unlike the tyincal form as Dr. Torrey's sjiecimens appear 

 at first sight, a careful examination fails to afford any distinction not fairly attributable to ditier- 

 ence of station. 



12. S. Lemmoni, Bebb. Branches slender, at first covered with a short ap- 

 pressed pubescence, becoming smooth : leaves lanceolate, acute or acuminate at both 

 ends, entire or remotely subserrate, silky-pubescent, very soon glabrate, paler or 

 scarcely glaucous beneath ; petioles slender (4 to G lines long) ; stipules small, semi- 

 ovate, acute, serrate, deciduous : aments oblong or cylindrical, rather densely fl(j\v- 

 ered, appearing with the leaves, on short peduncles bearing 2 or 3 small acute leaf- 

 like bracts : scales obovate, obtuse or somewhat acute, black, thinly pilose : capsules 

 ovate-lanceolate, acute, grayish-tomentose, 2 or 3 lines long : pedicel 4 to G times the 

 length of the nectary : style medium sized ; stigmas erect, entire. 



Var. melanolepis. Scales pitch-black and slightly or not at all hairy. 

 Var. macrostachya. Aments large and soft-villous (resembling those of S. 

 discolor) : lapsuh^s ta])criug to a produced style : peduncles more leafy. 



Var. sphserostachya. Aments about half an inch long, subglobose ; leaves 

 linear-lanceolate, entire, an inch long. — A divaricately much Ijranched little shridj ; 

 seemingly a depauperate or subalpine form. 



Sierra County (/. G. Lemmon, for whom it is named) ; Plumas County (Mrs. Pidsifer Ames, 

 Mrs. Austin) ; near Car.son Citv, Watson. A shrub rarely attaining the height of 15 feet, with 

 smooth olive-colored bark on the older branches. It exhibits much diversity in the character 

 of the aments, but the different forms apparently pass into each other throughout the .senes, and 

 the leaves furnish no distinctions. aS'. macrocarpa., Nutt., a little known species from Oregon, 

 differs especially in its smaller pale acute scales, glabrate cai)snles, and nearly .sessile stigmas. 

 Amon" Dr. Bolander's specimens from West Falls Meadows, 7,000 or 8,000 feet altitude, we find 

 staminate aments in which the filaments are united nearly to the anthers and unusually pubescent. 

 The material is too scanty to warrant more than a conjecture that this may be s, forma monstrosa 

 of S. Lcvunoni. 



1 3. S. AustineC, Bebb. A shrub or small tree, with very smooth light-gray bark ; 

 recent branches slender and but little divided, shining yellow or bronzed, very tough : 

 leaves narrowly oblanceolate, obliquely acuminate or falcate, attenuate at base, 

 smooth and bright green above except the yellowish midrib, glaucous and pubescent 

 beneath, the margin very slightly and obscurely subserrate ; stipules none : aments 

 appearing before the leaves, sessile, the .small bracts at base early deciduous, erect, 

 cylindrical-oblong, densely flowered ; scales obovate, dark, clothed with silky hairs : 

 capsules tapering- to a beak, tomeutose, about 2 lines long, shortly pedicelled so that 

 they are partially covered, even when mature, by the scales : styles produced; stigmas 

 erect, entire. 



Indian Valley, Plumas County, Mrs. R. M. Austin, — who in doing much to advance our 

 knowledge of the botauv of the Sierra Nevada has not neglected the Willow.s. Aments somewhat 

 as in S.fiderata, Anders., but that has proportionately .shorter and broader leaves, ".scarcely 2 

 inches long by i^ to 1 inch broad," thinner in texture and dull green above, and large serrulate 

 stiiiules. The figure given by the author (Mouogr. fig. 73) corresponds neither with his de- 

 scription nor wUh a Sketch of Scemann's specin'icn (in Herb. Kew) on which the species was 

 founded. 



14. S. Breweri, Bel)b. Branches long, very .slender and jiliant, pul)escent at 

 first, becoming smooth : leaves linear-lanceolate, acute or acuminate, sessile or nearly
