SALIX 



sordida, Kerner (S. cinerca x S. purpiirea. S. Ponte- 

 derdna, W. D. Koch, not Willd.). Tall upright shrub: 

 young branchlets tomentose, later glabrous, brown or 

 yellowish: Ivs. elliptic to lanceolate, acute, cuneate or 

 rarely obtuse at the base, irregularly serrate, pubescent 

 while young, later glabrous above, glabrescent and glau- 

 cous beneath: catkins on short, often leafy stalks; sta- 

 mens usually connate one-half; ovary pubescent with 

 short style. Eu. with the parents. 



aurita, Linn. Shrub, 3-8 ft.: branches spreading, 

 usually glabrous at maturity: stipules persistent, broad: 

 Ivs. short-petioled, obovate to elliptic, obtuse, usually 

 rounded at base, irregularly dentate or nearly entire, 

 pubescent on both sides or nearly glabrous above, 

 glaucous beneath, 1-2, rarely to 3 in. long: catkins 

 short-stalked or nearly sessile, a little before the Ivs., 

 the staminate broadly elliptic, with long filaments 

 hairy at base; the pistillate cylindric; ovaries hairy; 

 style very short or wanting. April. Eu., W. Asia to 

 Altai Mts. 



ambigua, Ehrh. (S. aurita x S. ripens). Shrub, about 

 3 ft., with creeping st.: branchlets glabrous: Ivs. elliptic 

 to lanceolate, somewhat rugose, pubescent, later gla- 

 brescent above, about 1 in. long: catkins a little before 

 the Ivs.; ovary pubescent; style rather long. In Eu. 

 with the parents. 



ludificans, White (S. aurita x S. phylicifolia). 

 Shrub: branchlets glabrous at maturity: stipules usually 

 persistent: Ivs. elliptic to narrowly obovate, crenulate, 

 glabrous at maturity, glaucous beneath: catkins rather 

 small, on leafy stalks, cylindric; ovary pubescent. N. 

 Eu., with the parents. 



sesquitertia, White (S. aurita x S. phylicifolia x S. 

 purpiirea). Intermediate in general appearance between 

 S. aurita and S. phylicifolia: Ivs. in shape like the 

 former but with the nervation of the latter and 

 nearly glabrous at maturity: stamens quite connate; 

 ovary pubescent with slender style. Observed in Eng- 

 land with the parents. 



grandifolia, Ser. (? S. appendicul&ta, Vill.). Shrub, 

 to 10 ft., with spreading branches: branchlets tomen- 

 tose while young; stipules often conspicuous, semi-cor- 

 date: Ivs. oval to obovate-lanceolate, acute, cuneate or 

 rounded at the base, crenately serrate, glabrous at 

 maturity except the pubescent midrib beneath, dark 

 green above, light green or glaucescent and reticulate 

 beneath, 2-6 in. long: catkins before or with the Ivs. 

 on short stalks with small bract-like Ivs. ; stamens hairy 

 below; ovary long-stalked, pubescent; style short. 

 Higher mountains of Cent, and S. Eu. 



neriifolia, Schleich. (S. grandifolia x S. purpurea. 

 S. Pontederana, Schleich., not Willd. S. austriaca, 

 Kerner). Shrub, to 6 ft., with upright slender branches: 

 young branchlets pubescent, later glabrous, greenish or 

 brown: stipules rather narrow: Ivs. obovate-lanceolate 

 to lanceolate, acute, serrulate, glabrous at maturity, 

 glaucescent and reticulate beneath, 2-3 in. long: cat- 

 kins shortly before the Ivs. ; filaments more or less con- 

 nate; ovary stalked, pubescent, with very short style. 

 Cent. Eu. with the parents. 



myrsinifdlia, Salisb. (S. nigricans, Smith. ? S. 

 spadicea, Chaix). Shrub, to 12 ft.: branchlets hairy 

 dr glabrescent, dull: stipules often rather large, sub- 

 cordate: Ivs. varying from elliptic, or rarely suborbicu- 

 lar to oblong-obovate or broadly lanceolate, usually 

 acute, rounded at tht base, serrate to nearly entire, 

 glabrous or glabrescent above, more or less pubescent 

 beneath, 1-3 in. long, usually blackish when dried: 

 catkins with or a little before the Ivs., short-stalked, 

 bracted or leafy at the base; staminate rarely exceed- 

 ing Min.; pistillate cylindric; ovary stalked, usually 

 glabrous, style slender. Eu., W. Asia to Kamchatka. 

 A very variable species. 



tetrapla, Smith (S. myrsinifdlia x S. phylicifolia). 

 Intermediate between the closely related parents. It 

 can best be recognized by the combination in various 

 degrees of the characters of the two species which are 

 chiefly the duller and more pubescent branches and 

 Ivs. and the larger stipules of S. myrsinifolia and the 

 more shining and glabrous branches and Ivs. and the 

 smaller stipules of S. phylicifolia. Occurs in Eu. 

 between the parents. 



phylicifSUa, Linn. (S. Hcolor, Ehrh.). Upright 

 shrub, to 3 or rarely 8 ft., with stiff and rather short 

 branches: branchlets glabrous, polished: stipules small, 

 caducous, or wanting: Ivs. short-petioled, elliptic or 

 elliptic-oblong, acute, rounded at base, nearly entire or 

 minutely crenate-serrate, glabrous at maturity, yel- 

 lowish green and glossy above, glaucous beneath, 1-3 

 in. long, not black when dried; catkins before or with 

 the Ivs., on short leafy stalks; ovaries pubescent or 

 sometimes glabrous, stalked; style rather long. N. and 

 Cent. Eu., N. Asia. 



To Salix, No. 24, add: Var. Gmelinii, Anderss. 

 (yar. songarica, Regel). Fls. with the Ivs.; ovary ses- 

 sile, obtuse with a short and thick style and long 

 stigmas. Russia, N. and Cent. Asia. 



After Salix, No. 24, insert three: 



stipularis, Smith (S. cinerea X S. viminalis. S. 

 holosericea, Willd.). Shrub or small tree: branchlets 

 long and stout, persistently pubescent: Ivs. lanceolate 

 to oblong-obovate, acute or acuminate, irregularly 

 serrulate or crenulate, hairy on both sides, more densely 

 beneath, 3-7 in. long: catkins before the Ivs., short- 

 stalked or nearly sessile; stamens very long; ovary 

 stalked, pubescent, with short style and slender stigmas. 

 Eu., N. Asia, with the parents. 



daphnoides. Vill. Tall shrub, to 30 ft., rarely tree: 

 branchlets yellowish or brownish, bloomy, glabrous: 

 stipules cordate: Ivs. short-stalked, lanceolate, acu- 

 minate, glandular-serrulate, glabrous, glaucescent be- 

 neath, 1^-3 in. long: catkins sessile, before the Ivs.; 

 staminate nearly 2 in. long, filaments sometimes 

 united at the base; pistillate rather shorter; ovary short- 

 stalked, glabrous, with long style. N. and Cent. Eu., 

 N. and Cent. Asia. 



acutifolia, Willd. (S. daphnoides var. acutifdlia, 

 Doll). Closely related to the preceding species: branch- 

 lets darker colored, more bloomy: stipules lanceolate, 

 Ivs. narrower and longer, lanceolate to linear-lanceo- 

 late, long-acuminate: catkins smaller. Eu., N. Asia. 



After Salix, No. 27, insert three: 



Piperi, Bebb. Shrub, to 20 ft.: branchlets glabrous, 

 dark brown: Ivs. elliptic-oblong, obovate or oblanceo- 

 late, acute, undulate crenate or nearly entire, glabrous, 

 glaucous beneath, 46 in. long: catkins sessile or short- 

 peduncled; stamens united or free at base; ovary 

 smooth; style rather long. Wash. 



hastata, Linn. Shrub, to 6 ft., young branchlets 

 pubescent, older glabrous, brown: stipules often very 

 large, obliquely ovate: Ivs. elliptic or ovate, acute, gla- 

 brous, irregularly serrulate, l%-2% in. long: catkins 

 with the Ivs., in leafy stalks; filaments glabrous; ovary

 Wimmeri, Kerner). Tall shrub; young branchlets 

 densely pubescent, older brown, glabrous, often bloomy:
