 larger fls. in dense many-fld. corymbs. G.C. III. 51 : 

 suppl. 19. M.D.G. 1913:17. One of the handsomest 

 deutzias, but has proved hardy only under protection 

 at the Arnold Arboretum. 



EE. Anthers borne at the end of the filaments. 



F. Fls. usually pinkish outside (hybrids of D. purpu- 



rascens) .

 purdscens). Lvs. oblong-ovate, acuminate, rounded or 

 broadly cuneate at the base, serrulate with spreading 

 teeth, rough above, slightly stellate-pubescent beneath, 

 lJ^-3 in. long: fls. in broad corymbs, white, with 

 spreading petals, partly imbricate in bud; filaments 

 strongly toothed; anthers short-stalked; styles shorter 

 than stamens; sepals triangular-ovate, about as long 

 as calyx-tube. G.C. III. 52:45. F.S.R. 3, p. 193. A.F. 

 31:100, 101. M.D.G. 1907:376, fig. 5; 377, fig. 8.

 purdscens). Lvs. oblong to ovate-oblong, short-acumi- 

 nate, broadly cuneate at the base, serrulate,

1-2 J^ in. long: fls. in rather small corymbs, 

 pinkish, white in the center, light carmine out- 

 side, cup-shaped, %in. across; petals mostly 

 imbricate in bud; stamens half as long as petals;

 as long as the anthers; styles shorter 

 than stamens. M.D.G. 1913:25. G.

 not exceeding %m.', fls. white, with spreading elliptic

 stamens sometimes inserted inside a little below the 

 apex. June. Cent. China. Var. major, Veitch. Fls. 

 about 1 in. across. G. 30:307. R.B. 32, p. 174. M.D.G.

13. Vilmorinae, Lemoine. Shrub, to 5 ft. : Ivs. oblong- 

 lanceolate, acuminate, narrowed at the base, serru- 

 late, thinly stellate-pubescent above, densely so below 

 and grayish white, 2-3 in. long: corymbs loose and 

 large; pedicels J^-J^in. long; fls. more than ^in. across; 

 larger stamens only slightly shorter than petals; the 

 teeth of the filaments shorter than the stalks of the 

 anthers; styles as long as stamens. May, June. Cent.

 rowed toward the apex, without teeth. 



14. Wflsonii, Duthie. Shrub, to 6 ft.: Ivs. elliptic- 

 lanceolate to oblong-lanceolate, short-acuminate,

 than %in. across; stamens a third shorter than the 

 petals; the shorter filaments usually abruptly contracted 

 or sometimes with short obtuse teeth; calyx-lobes 

 oblong-ovate, about as long as tube. May, June. Cent. 

 China. B.M. 8083. G. 30:373. G.M. 51:473. M.D.G. 

 1912:27; 1913:16. 



cc. Infl. 1-8-fld.; filaments with long and slender recurved 

 teeth. 



15. grandiflora, Bunge. Shrub, to 6 ft.: Ivs. ovate, 

 acuminate, rounded at the base, unequally and closely 

 denticulate, rough pubescent above, whitish stellate- 

 tomentose below and reticulate, 1-2 H in. long: fls. 

 white, nodding, with slightly spreading petals about 

 %in. long; stamens about half as long as petals; calyx- 

 lobes lanceolate, twice as long as tube. April, May. 

 N. China. A very distinct species, the earliest of all 

 to bloom, the fls. appearing with the Ivs.; has proved 

 perfectly hardy at the Arnold Arboretum. 



AA. Petals imbricate in the bud (or partly imbricate in 

 the hybrid); fls. white. 



16. parvifldra, Bunge. Shrub, to 6 ft., with erect 



branches: Ivs. ovate 

 or oblong-ovate, usu- 

 ally narrowed at the 

 base, finely serrate, 

 with stellate hairs on 

 both sides, often 

 grayish green be- 

 neath, 2-3 in. long: 

 fls. in many - fld. 

 corymbs; petals 

 roundish obovate, 

 spreading, imbricate 

 in the bud; longer

 gustifblia, D i p p . ) . 

 Fig. 1247. Spreading shrub, to 3 ft. : Ivs. elliptic-lanceo- 

 late, finely serrate with appressed teeth, with sparse 

 stellate hairs above, nearly glabrous beneath, lJ^-3 

 in. long: fls. in large corymbs or broad panicles, pure 

 white; petals broadly ovate, spreading, partially

 439. A very desirable shrub, more vigorous and with 

 showier fls. than D. gracilis. Excellent for forcing. 



Var. compacta, Lemoine. Dwarfer and of more com- 

 pact habit. D. Boule de Neige, Lemoine, with creamy 

 white fls. (Gng. 8:306) and D. Avalanche, Lemoine, 

 with pure white fls., are exceedingly floriferous forms.

 deldbrum, Rehd. (D. gracilis X D. Sieboldiana. D. gracilis var. can- 

 delabrum, Lemoine). Shrub with slender branches and large white
