1. nigra, Marshall. BLACK WILLOW. Fig. 

 2233. 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. Var. 

 pendula is cult. 



2. amygdaloldes, Andersson. 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. Central and western N. Amer. 



3. 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 lan- 

 ceolate-acuminate, serrate, dark green, shin- 

 ing above: aments large, appearing with the 

 Ivs.; scale pale green, deciduous; stamens 

 4-5: ovary pedicelled, rather obtuse, glabrous. 

 E. N. Amer. A beautiful plant, deserving of 

 more extensive cultivation. 



4. pentandra, Linn. (S. laurifblia, Hort. ). 

 BAY-LEAF or LAUREL-LEAF WILLOW. Shrub 

 or small tree, 8-20 ft. high : branches chest- 

 nut color: Ivs. large, elliptic to broadly ob- 

 lanceolate, acuminate, shining and dark green 

 above, paler beneath ; aments appearing after 

 many of the Ivs. are fully developed, not 

 conspicuous. Europe and Asia. 



5. fragilis, Linn. (S. vtridis, Fries. S.Rus- 

 sellidna, Sm. ). BRITTLE WILLOW. Fig. 2233. 

 Tree, 50-60 ft. high, excurrent in habit and 

 of very rapid growth: branches brown, ob- 

 liquely ascending: buds medium size, pointed: 

 Ivs. large, lanceolate, acuminate, glabrous or 

 slightly hairy when young, scarcely paler be- 

 neath, glandular serrate : aments appearing 

 with the ivs. (the staminate tree rare in 

 America), seldom bearing good seed, slender; 

 scales deciduous. Eu., N. Asia. Gn. 19, p. 

 517; 55, p. 89. Frequently cultivated and 

 also growing spontaneously in many places. 

 A company of promoters induced many Amer- 

 ican farmers to plant hedges of this Willow 

 some fifty years ago. Many of these occur 

 now throughout the country, the trees being 

 40-50 feet high. A stake cut from a tree and 

 driven in the ground will soon establish it-

self 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. 



6. alba, Linn. WHITE WILLOW. Fig. 2234; 

 also 2230-2. Large tree, with short and thick 

 trunk, not excurrent in habit : branches yel- 

 lowish 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. 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 America and has been known as /S'. 

 alba, var. argentea, S. splendens, Bray, and 

 S. regalis, Hort. These forms, not easily 

 distinguishable from one another, can be 

 readily distinguished from the following spe- 

 cies. 



7. 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 leaves. Abundant in E. N. Amer. 

 Mn. 8, p. 2"> (erroneously as . a Jba). Dis- 

 playing many variations, the most obvious of 

 which are: Var. aurea, Salisb. (var. auran- 

 tlaca, Hort.), branches golden yellow, espe- 

 cially just before the leaves appear in spring. 

 Var. Britzensis, Hort., bark red. These as 

 well as other choice varieties are grafted. Var. 

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



8. Babyl6nica, Linn. (S. p6ndula, Moench). 

 NAPOLEON'S WILLOW. Fig. 2234. A tree of 

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

 der, olive-green branches ; buds small, acute: 

 Ivs. 2-6 in. long, attenuate at base and apex: 

 aments appearing with the Ivs., slender, the 

 pistillate green: capsule small, 1 in. long. 

 Caucasus. Gn. 1, p. 371; 34, p. 527; 39, p. 

 72; 55, p. 92. S.H. 1:261. -Long known in 

 cultivation and often grown in cemeteries. 

 Several forms recognized, some of which 

 may be hybrids: Var. aurea, Hort., branches 

 golden yellow. Var. annularis, Forbes, Ivs. 

 twisted back so as to form a sort of ring. 

 Var. dolorosa, Rowen. WISCONSIN WEEPING 

 WILLOW. Lvs. glaucous beneath; hardy far- 

 ther north. Var. Salamonii, Hort., more vigor- 

 ous and upright in habit, a form originating 

 in France. Gn. 55, p. 19. S.H. 2:373. 8. 

 Salmonii of one catalogue is perhaps an error 

 for this. Var. Japonica, Thunb., Ivs. more 

 decidedly toothed ; aments longer and looser. 



9. elegantissima, Koch. THURLOW'S WEEP- 

 ING WILLOW. Tree with more spreading 

 habit and larger crown than S. Babylonica: 

 branches long and pendent, yellowish green, 

 sometimes blotched with brown: appears to 

 be more hardy than S. Babylonica. Japan. 

 Gn. 55, p. 24. S.H. 2:363. R. Sieboldii, Hort., 

 is this species or is closely related. 



10. interior, Rowlee (S. rubra, Rich, not 

 Huds. S. longifolia, Muhl., not Lam. S. 

 fluvidtilis, Sargent and other recent authors 

 in part). Fig. 2234. 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 ca- 

 nescent, sessile, linear-elliptical, remotely den- 

 tate, the teeth narrow, sometimes quite spin- 

 ulose: stipules conspicuous, ear-shaped, ob- 

 scurely denticulate, deciduous : aments of
