1. Bonplandiana, Kunth. A branching 

 shrub or low tree with coriaceous Ivs. 5-6 in. 

 long, dark green above and glaucous beneath: 

 aments usually precocious in the axils of 

 mature Ivs. Native of Mex. and the S. W. 

 U.S. 



2. nigra, Marsh. BLACK WILLOW. Fig. 

 3526. Tree, 30-40 ft. high: bark flaky, often 

 becoming shaggy: twigs brittle at base: buds 

 small: Ivs. lanceolate, green both sides, finely 

 and evenly serrate: aments 1-2 in. long; 

 scales oblong, deciduous; stamens 3-6; ovary 

 ovate-conical, glabrous; style short but dis- 

 tinct. E. N. Amer. Var. falcata, Pursh. Lvs. 

 elongated, narrow and falcate. 



3. amygdaloides, Anders. PEACH -LEAF 

 WILLOW. Tree, 30-40 ft. high: bark longi- 

 tudinally furrowed, less inclined to be flaky: 

 Ivs. broader, glaucous beneath, on rather 

 long, compressed petioles: aments loosely fld.; 

 ovary lanceolate-conical; style very short. 

 Cent, and W. N. Amer. 



4. lucida, Muhl. Shrub or low bushy tree, 

 6^-15 ft. high: branches yellowish brown and 

 highly polished: buds large, flattened, and 

 recurved at the apex: Ivs. large, broadly 

 lanceolate - acuminate, serrate, dark green, 

 shining above: aments large, appearing with 

 the Ivs.; scale pale green, deciduous; stamens 

 4-5; ovary pedicelled, rather obtuse, gla- 

 brous. E. N. Amer. A beautiful plant, de- 

 serving of more extensive cult. 



5. pentandra, Linn. (S. laurifolia, Hort. 

 S. Humboldtiana, Hort. not Willd.). BAY-LEAP 

 or LAUREL-LEAF WILLOW. Shrub or small 

 tree, 8-20 ft. high: branches chestnut-color: 

 Ivs. large, elliptic to broadly oblanceolate, 

 acuminate, shining and dark green above, 

 paler beneath: aments appearing after many 

 of the Ivs. are fully developed, not conspicu- 

 ous. Eu. and Asia. 



6. fragilis, Linn. (S. viridis, Fries. S. Rus- 

 sellidna, Smith). BRITTLE WILLOW. Fig. 

 3526. Tree, 50-60 ft. high, excurrent in 

 habit and of very rapid growth: branches 

 brown, obliquely ascending: buds medium size, pointed: 

 Ivs. large, lanceolate-acuminate, glabrous or slightly 

 hairy when young, scarcely paler beneath, glandular 

 serrate: aments appearing with the Ivs. (the staminate

 (Xjfl 



tree rare in Amer.), seldom bearing good 

 seed, slender; scales deciduous. Eu., N. Asia. 

 Gn. 19, p. 517; 55, p. 89. Frequently cult, 

 and also growing spontaneously in many 

 places. A company of promoters induced 

 many American farmers to plant hedges of 

 this willow some 50 years ago. Many of these 

 occur now throughout the country, the trees 

 being 40-50 ft. high. A stake cut from a tree 

 and driven in the ground will soon establish 

 itself and grow into a tree. Var. decipiens, 

 Hoffm. Twigs yellow: buds black in winter: 

 Ivs. smaller and brighter green. Probably a 

 hybrid with another species. 



7. alba, Linn. WHITE WILLOW. Fig. 3527; 

 also Figs. 3523-3525. Large tree, with short 

 and thick trunk, not excurrent in habit: 

 branches yellowish brown: Ivs. ashy gray and 

 silky throughout, giving a white appearance 

 to the whole tree, 2-4 in. long, elliptical. Eu. 

 Gn. 55, p. 87; 61, p. 7. Heretofore associated 

 with the next species, from which it differs in 

 color of twigs and vesture and color of Ivs., 

 as also in its general habit. It is only 

 occasionally seen in Amer. Var. splendens, 

 Anderss. (S. alba var. argentea, Wimm. S. 

 regalis, Hort.). Lvs. densely silky on both 

 sides, nearly silvery-white while young. The 

 forms of this species not easily distinguish- 

 able from one another, can be readily distin- 

 guished from the following species. 



8. vitellina, Linn. (S. bldnda, Anderss.). 

 YELLOW WILLOW. Becoming a very large and 

 venerable appearing tree, the rather short 

 trunk often 4 ft. or more in diam. It is often 

 pollarded. The crown is deliquescent and 

 rounded in outline. Branches yellow: Ivs. 

 silky-hairy when young, glabrous when ma- 

 ture, glaucous beneath, the whiteness inten- 

 sified after the Ivs. fall: aments appearing 

 with the Ivs. Abundant in E. N. Amer. 

 Mn. 8, p. 25 (erroneously as S. alba). Dis- 

 playing many variations, the most obvious of 

 which are: Var. aurea, Salisb. (var. aurantiaca, 

 Hort.), branches golden yellow, especially 

 just before the Ivs. appear in spring. Var. 

 britzensis, Hort., bark red. These as well as 

 other choice varieties are grafted. Var. pen- 

 dula, Hort. (S. aiirea pendula, Hort. S. alba 

 var. vitellina pendula, Rehd. S. babylonica 

 aurea&udS. babylonica ramulis aureis, Hort.). 

 Tree of weeping habit, similar to S. babylon- 

 ica, with yellow branches. M.D.G. 1898:88. 

 Gn. 55, pp. 15, 22. S.H. 2:361, 371. 



9. babylfinica, Linn. (S. pendula, Moench). 

 NAPOLEON'S WILLOW. Fig. 3527. A tree of 

 weeping habit, 30-40 ft. high, with long 

 slender olive-green or purplish branches: 

 buds small, acute: Ivs. 2-6 in. long, atten- 

 uate at base and apex : aments appearing with 

 the Ivs., slender, the pistillate green, 1 in. long, 

 caps, small. China. Gn. 1, p. 371; 34, p. 527; 

 39, p. 73; 55, p. 92. S.H. 1:261. F.E. 19:574. 

 G.W. 2, p. 31. Long known in cult, and 

 often grown in cemeteries. Tender N. Var. 

 annularis, Forbes, Ivs. twisted back so as to 

 form a sort of ring. 



10. Salam6mi, Carr. (<S>. babylonica var. 

 Salambnii, Carr.; sometimes erroneously 

 spelled Salcmonii or Salmonii). Hybrid be- 

 tween S. alba and S. babylonica. Similar to 



S. babylonica, but less pendulous: tree with ascending 

 branches and pendulous branchlets: Ivs. similar to 

 those of S. babylonica, but sparingly silky-pubescent 

 on both sides: pistillate catkins with more pubescent
