43. Fontenaysii, Billiard (S. fontenaysiensis, Dipp. 

 S. canescens x S. salicifdlia). Shrub, 6 ft. high, with 

 slender, upright branches: Ivs. oval or oblong-oval, 

 rounded at both ends, crenately serrate above the 

 middle, pale bluish green beneath, almost glabrous, 

 1-2 in. long : fls. white or pink, in 1 J^-3-in.-long panicles ; 

 petals orbicular, about as long as stamens; sepals 

 spreading in fr. June, July. Of garden origin. Not 

 quite hardy N. Var. alba, Zabel, is the white-fld., var. 

 rosea, Zabel, the pink-fld. form. S. pruinosa, Zabel 

 (S. brachybotrys, Lange. S. luxuriosa, Hort. S. 

 canescens x S. Douglasii), is a similar form, but the 

 Ivs. are tomentose beneath and the fls. pink. 



44. conspicua, Zabel (S. albiflora x S. alba). Upright 

 shrub, 3 ft. high, with dark brown puberulous branches: 

 Ivs. elliptic-oblong, acute at both ends, simply or doubly 

 serrate, almost glabrous, 1J^-2K in. long: fls. pinkish 

 white, in broad finely pubescent panicles; petals shorter 

 than stamens. July-Sept. Handsome form. A similar 

 hybrid is S. syringaeflSra, Lem. (L. albiflora x S. salici- 

 fdlia), with oblong-lanceolate or lanceolate Ivs., serrate 

 above the middle, and pink fls. Closely allied is also 

 S. semperflorens, Zabel (S. japdnica x S. salicifblia, S. 

 japdnica or S. Fdrtunei var. paniculdta, Hort.). Higher 

 than the former: Ivs. oblong-lanceolate, usually doubly 

 serrate: fls. pink. R.H. 1860, pp. 496, 497. Gn. 45, p.

45. ndtha, Zabel (S. corymbosa x S. latifblia}. Shrub, 

 3 ft. high, with brown, glabrous branches: Ivs. broadly 

 ovate to obovate, short-petioled, coarsely and doubly 

 serrate, almost glabrous, 1-2 in. long: fls. white to 

 pinkish white, in broad, glabrous panicles; stamens 

 almost twice as long as the orbicular petals. July, Aug. 

 Of garden origin. 



46. pyramidata, Greene. Possibly hybrid between 

 S. lucidasmd S. Menziesii. Upright shrub, 3 ft. high: 

 Ivs. oval-oblong to oblong, acutish or obtuse, usually 

 doubly serrate above the middle, glabrous or nearly so, 

 1/^-3 in. long: panicles l%-3% in. long, rather dense, 

 puberulous: fls. pinkish or almost white. July. Found 

 wild in Ore. and Wash. 



47. sanssouciana, Koch (S. Douglasii x S. japdnica. 

 S. Regelidna, Hort. S. Nobledna, Hook.). Shrub, 4 ft. 

 high, with striped, finely tomentose branches: Ivs. 

 oblong-lanceolate, sharply and usually doubly serrate, 

 grayish tomentose beneath, 2-3 H in. long: fls. pink, in 

 broad corymb-like panicles: follicles glabrous, with 

 spreading styles. July, Aug. Of garden origin. B.M. 

 5169. I.H. 8:286. An allied form is S. intermedia, 

 Lemoine (S. albiflora x S. Douglasii) , similar in habit to 

 S. syringseflora but with the Ivs. tomentose beneath. 



48. Watsoniana, Zabel (S. Douglasii var. Nobledna, 

 Wats. S. Nobledna, Zabel. S. Douglasii x S. densifldra). 

 Shrub, 4 ft. high, similar to the former: Ivs. oblong or 

 narrowly oblong, usually rounded at the base, acute, 

 sharply serrate above the middle, grayish-tomentose 

 beneath, 1-3 in. long: fls. light pink, in dense broadly 

 pyramidal, tomentulose panicles 3-6 in. high; petals half 

 as long as stamens; sepals reflexed in fr.; styles erect. 

 June, July. Natural hybrid, found in Calif. S. subvil- 

 losa, Rydb., apparently belongs here. A similar form 

 is S. pachystachys, Zabel (S. corymbosa x S. Douglasii), 

 with broader Ivs. and fls. of paler pink. G.C. III.

49. salicifolia, Linn. (S. sibirica, Raf. S. salicifdlia 

 var. cdrnea, Ait.). Upright shrub, 5 ft. high, with 

 terete yellowish brown branches puberulous when 

 young: Ivs. oblong-lanceolate to lanceolate, sharply and 

 sometimes doubly serrate with often incurved teeth, 



in. long: fls. light pink or whitish, in oblong, 

 dense, tomentulose panicles leafy below, the Ivs. exceed- 

 ing the ascending ramifications; stamens twice as long 

 as petals; sepals upright in fr.: follicles ciliate at the 

 inner suture. June, July. S. E. Eu. to Japan and 

 probably Alaska. R.F.G. 24:152. G.W.H. 82. Var. 

 grandiflora, Dipp. (S. grandiflora, Lodd.). Lower, with 

 larger, lighter pink fls. L.B.C. 20:1988.

 lanceoldta, Borkh.). QUEEN OF THE MEADOW. MEADOW- 

 SWEET. Attractive upright shrub, attaining 6 ft., with 

 reddish brown branches puberulous when young: Ivs. 

 narrow, oblong to oblanceolate, acute, usually regularly 

 simply serrate, 1^-2H in. long: fls. white, in leafy 



pyramidal tomen- 

 tulose panicles, 

 the lower spread- 

 ing ramifications 

 much longer than 

 their supporting 

 Ivs.; stamens 

 white, usually as 

 long as petals : fol- 

 licles quite gla- 

 brous. June Aug.

 ing shrub, 2-5 ft. 

 high, with bright 

 or dark red-brown 

 glabrous twigs: 

 Ivs. broadly oval 

 to obovate or ob- 

 long, usually 

 coarsely and often 

 doubly serrate, 

 1^-3 in. long: fls. 

 white, larger than 

 those of S. alba,

 blushed and with 

 the stamens and 

 disk more or less 

 pinkish; panicles 

 quite glabrous, broadly pyramidal, with spreading and 

 elongated ramifications; stamens longer than petals. 

 June-Aug. Newfoundland and Canada to N. C. Em. 

 2:485. G.C. III. 43:417. This and the preceding 

 species have been referred by most American botanists 

 to S. salicifolia. S. alba is chiefly found west, S. lati- 

 folia east of and on the Alleghanies, while the true S. 

 salicifolia is an Old- World species. 



52. Menziesii, Hook. (S. Douglasii var. Menziesii, 

 Presl). Upright shrub, 4 ft. high, with brown, at first 

 puberulous, branches: Ivs. oblong-obovate to oblong, 

 coarsely and unequally serrate above the middle, pale 

 green beneath, l%-3 in. long: fls. small, pink, in rather 

 narrow, 5-8-in.-long panicles; stamens more than
