gg SALICACE.E. SalU. 



Santa Barbara {.Urs. El wood Conpcr); Santa Ti-u/ (Anderson), ['.car ValU>y {TSohindcr), and ex- 

 temling noithwaril to Alaska. A most beautilul and (listin('t species, leniaikable for the silvery 

 under-siul'ace of the leaves. Leaves about an ineb bmad above tlie middle : IViiiting aments 3 

 or 4 inches long: style and pedicel of about eiinul length. Niittall ealls this " Velvet Willow." 

 The variety «/(!7i(s///('//«, collected on a "high mountain near Donner Tass" by I)i: Turrcij, 1865, 

 accords essentially' (excepting the pointed leaves) with the description of S. c/ilurojiliijlla, var. 

 pcllita, Anders., though when compared with Dr. Lyall's specimens from tiie Hocky Aiouiitains, 

 cited by the author, tlie discrepancy is greater; here we tind the leaves 6 to l) lines or nearly an inch 

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

 been collected in Oregon and British America by Ila/l and Muanin, apiiearing like ,S'. Sitc/icasii 

 modified by growing in the shade. Unlike the tyjiical form as Dr. Torrey's specimens apjx-ar 

 at first sight, a careful examiuatiun fails to adord any distinction not fairly attributable to diller- 

 cnce of station. 



12. S. Lemmoni, iVlil), liraiidics slender, at iirst eovered willi a short ap- 

 ]»vosse(l puliivseeiice, heeoiiiiiig siiioolli : leaves laiice(dale, aciilo ov ai'tiliiiiiati! at hnlli 

 ends, entire or remotely snl)seiTato, .silky-pnliesceiit, very .soon j^laltrate, paler or 

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

 ovate, acute, serrate, deciduous : aments oblong or cylindrical, rather densely flow- 

 ered, appearing with the leaves, on short peduncles l)earing 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: i)edicel -1 to (i times the 

 length of the, nectary : style medium si/eil ; stigmas erect, entire, 



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



Var. macrostachya. Aments large and sol't-villons (resembling those of S. 

 discolor) : capsides ta|)ering to a produced style : peduncles more leafy. 



Var. sphaerostachya. Aments about half an inch long, subglobo.se; leaves 

 linear-lanceolate, entire, an inch long. — A divaricately much branched little shrul) ; 

 seemingly a depauperate or subalpine form. 



Sierra County (/. O. Lcmvum, for whom it is named); Plumas Comity (.'A-.s'. T'nlsifcr Aui'S, 

 Mrs. Atislin) ; near Carson City, U'nisuu. A shrub rarely attaining the heiglit of 16 feet, with 

 smooth olive-colored bark on the older branches, it exhibits much diversity in tlie character 

 of the aments, but the different forms apparently jiass into each other ilirougliout the series, and 

 the leaves fiunish no distiui'tions. ,S'. viticroniri„i, Nutt., a little known species from Oregon, 

 diliers especially in its smaller pale ac\ite scabs, glal)rate capsules, and nearly sessile stigmas. 

 Among Dr. Bolander's si)ecimens from West Falls Meadows, 7,000 or 8,000 feet altitude, we find 

 stamimite aments in winch the filaments are united nearly to tiie antlieis and unusually pubescent. 

 The material is too scanty to wariant more than a conjecture that this may Ijc uj'ur,iia inonstrosa 

 of S. Loniiioni. 



13. S. Austillce, Debb. 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, ol)li(iuely acuminate or lalcate, attenuate' at base, 

 smooth and bright green above except the yellowi.sh midrib, glaucous and pidiescent 

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

 appearing before the leaves, sessile, the small bracts at Ijase 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 pedicelletl so that 

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

 erect, entire. 



Indian Valley, Plumas County, Mrs. II. M. Auslin, — \\\\n in doing much to advance i)ur 

 knowledge of the botany of the Sierra Nevada has not neglected the Willows. Aments somewluit 

 as in S. Jakrata, Anders., but tliat has proportionately siiorter and broader leaves, ".scarcely '2 

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

 sti))ules. The ligure given by the author (Monogr. lig. 73) conesponds ncitlier with his de- 

 scription nor witli a sketch of Seeiiiaiiii's specimen ^ill Ileib. Kew) on which the species \Uis 

 founded. 



14. S. BrCTVeri, r>ebb. TJranches long, very slender and pliant, pubescent at 

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