axis and long-ciliate scabs. Originated in 

 M.D.G. 1898:89. Gn.55,p. 19. S.H.2:373. 

 S. sepulcralis, Simonkai, belongs here. 



11. bUnda, Anderss. (S. Petzoldii, Hort. 

 S. babylonica var. dolor osa, Rowen; possibly 

 also S. penduhna). WISCONSIN WEEPING 

 WILLOW. A hybrid of S. babylonica and S. 



Jragilis. Tree with spreading limbs and pen- 

 dulous branches; branches brownish green or 

 brown: Ivs. lanceolate or narrow-lanceolate, 

 long - acuminate, serrulate, glabrous, dark 

 green above, glaucous beneath, 3-6 in. long 

 and }'3-?4Ui- broad: fls. with the Ivs.; stamens 

 2; ovary short-stalked, glabrous, with one 

 gland at the base, half as long as the pedicel. 

 Of garden origin. 



12. elegantissima, Koch (S. Sieboldii, 

 Hort.). THURLOW'S WEEPING WILLOW. Tree 

 with more spreading habit and larger crown 

 than S. babylonica: branches long and pen- 

 dent, yellowish green, sometimes blotched 

 with brown: appears to be more hard}' than 

 S. babylonica. Origin unknown. M.D.G. 



- :88. Gn. 55, p. 24. S.H. 2:363. Said to 

 be of Japanese origin; probably only a form 

 of S. blanda. 



13. Safsaf, Forsk. EGYPTIAN WILLOW. A 

 tree in general appearance like S. alba or S. 

 babylonica. Several varieties have been de- 

 scribed. The mature Ivs. are bright green 

 above and glaucous beneath, 3-5 in. long and 

 over J^in. wide. X. E. Afr., where it is fre- 

 quently cult, along highways. Intro, into 

 Italy many years ago. 



14. longifolia, Muhl. (S. rubra, Rich., not 

 Huds. 5. interior, Rowlee. S.flundtilis,Srg., 

 and other recent authors in part, not Xutt.}. 

 Fig. 3527. Varying in stature from a low 

 shrub to a small tree, usually growing along 

 streams and lake-shores: twigs smooth and 

 brown to densely tomentose and gray: buds 

 plano-convex, with an obtuse and rounded 

 apex, very small: Ivs. nearly or quite smooth, 

 sparsely canescent to extremely canescent, 

 sessile, linear-elliptical, remotely dentate, the 

 teeth narrow, sometimes quite spinulose: 

 stipules conspicuous, ear-shaped, obscurely 

 denticulate, deciduous: aments of late spring 

 on short lateral peduncles, which bear 4-6 

 Ivs.. those borne later in the season on much 

 longer leafy branches, very loosely fld.: fls. 

 fascicled in clusters of 2-5 on the axis, a dis- 

 tinct interval between the fascicles, first ap- 

 pearing in May and often bearing a second set 

 of aments in early summer; scales usually 

 glabrous or somewhat hairy toward the base, 

 narrowly oblong, yellowish, deciduous after 

 flowering; filaments crisp-hairy below, smooth 

 above: caps, sessile, clothed when young with 

 appressed silvery hairs, becoming nearly 

 smooth at maturity; stigmas short, sessile. 

 Cent. X. Amer. The pistillate ament, lax at 

 anthesis, becomes more so as the caps, 

 mature, and by this character the species can 

 easily be distinguished from related species. 



15. argophylla, Xutt. (8. longifolia var. 

 argophylla, Anders. S. fluvidtilis var. argo- 

 phylla, Sarg. S. Hindsiana, Benth.). Tree 

 or large shrub, 12-18 ft. high, forming dense 

 thickets but not growing in clumps: branches 

 nearly glabrous and exceedingly tough: bark 

 turning from brown to bright yellow or orange 

 just before blooming, making a thicket of it 

 a most conspicuous object : Ivs. narrowly lan- 

 ceolate, closely sessile, entirely or rarely min- 



France.

3527. Leaves of 

 willows. 7, Salizalba; 

 S. S. babylonica; 9, S. 

 longifolia; 10, S. ros- 

 trata; 11, S. tristis; 

 12, S. discolor. (XM) 



utely and remotely denticulate, clothed equally on both 

 sides with an appressed silky pubescence, which more 

 or less conceals the veins; stipules obsolete: 

 scales oblong and obtuse in the staminate 

 ament, narrower and more acute in the pistil- 

 late; lower half of the filament densely crispy 

 hairy: caps, lanceolate, covered with straight 

 appressed silky hairs, closely sessile; stigmas 

 sessile; mature caps, often nearly glabrous. 

 Occasionally the Ivs. remain upon the plant 

 over winter, the young shoots appearing in 

 then* axils in spring. Ament surpassed in 

 length by its leafy peduncles; appearing in 

 May in Ore. and X. Calif, and flowering 

 intermit tenth- all summer. This species is dis- 

 tinguished by its narrowly lanceolate, entire 

 Ivs., obsolete stipules, small and rather nar- 

 row aments, erose scales, and hairy caps. S. 

 argophylla occurs on the Pacific slope from 

 S. Calif, to Brit. Col. It is a western repre- 

 sentative of the long-lvd. willows. Xot ad- 

 vertised, but a beautiful species common along 

 streams and irrigation ditches. 



16. balsamifera, Barr. Fig. 3528. A much- 

 branched clean-looking shrub, with shining 

 colored twigs, sometimes almost tree-like: 

 glabrous: Ivs. short -oval to lance -oblong, 

 rounded and sometimes somewhat cordate at 

 base, glandular-serrulate, thinnish and fra- 

 grant, dark green above and pale or glaucous 

 and also prominently reticulate beneath: 

 fertile aments becoming lax and open, the 

 slender pedicels of the carpels much longer 

 than the glands, the style short. Along the 

 northern borders of the U. S. and far north- 

 ward ; an attractive species. G. F. 6:29 

 (reduced in Fig. 3528). 



17. Caprea, Linn. GOAT WILLOW. Fig. 

 3529. A small tree, 12-25 ft. high, with up- 

 right branches: Ivs. large, 2-5 in. long, 1-3 

 in. wide, rounded or subcordate at base, 

 rugose, very variable: aments appearing be- 

 fore the Ivs., large and showy, especially the 

 staminate ones. Eu., Asia. The typical" form 

 often occurs in yards where it has sprouted 

 from the stock upon which the more popular 

 but scarcely more ornamental variety, pen- 

 dula, has been grafted. Var. pendula, Hort. 

 KILMARNOCK WILLOW. Dwarfed form, grafted 

 on stock about 4 ft. high, and forming a 

 weeping shrub. Often planted in yards. S. 

 multinerris is supposed to be a hybrid, and 

 probably belongs with S. Caprea. S. Caprea 

 var. tricolor, Hort., is said by F. W. Kelsey 

 to be a round-headed tree, with ''tricolored 

 foliage;" probably a form of S. aurita. S. 

 palmsefolia, Hort., is said by F. W. Kelsey to 

 be of vigorous growth, with large, deep green 

 Ivs. and reddish purple young wood. 



18. discolor, Muhl. PUSSY WILLOW. Figs. 

 3521, 3522, 3527. A shrub or short-trunked 

 tree. 10-20 ft. high: buds very large and 

 nearly black: Ivs. smooth and bright green 

 above, whitish beneath, irregularly crenate- 

 serrate: aments appear early in spring, before 

 the Ivs., closely sessile, enveloped in long, 

 silkj- hairs. E. X. Amer. Worthy of more 

 extended cult, and thriving in dry ground. 



19. rostrata, Rich. (P. Bebbiana, Sarg.). 

 Fig. 3527. A small tree, 10-20 ft. high, with 

 short but distinct trunk: buds of medium size, 

 conical, brown: Ivs. dull green and downy 

 above, prominently veined and hairy beneath: 

 aments appearing with the Ivs., the staminate 

 beautiful golden when in flower; scales narrow
