SPIRJEA 



SPIR^A 



across ; stamens little longer than petals ; sepals reflexed 

 in fr. : follicles pubescent only at the inner suture, with 

 spreading styles. June, July. Himalayas. B.M. 2426. 

 L.B.C. 13:1268. Only half-hardy North. 



29. expansa, Koch (S. bella var. expdnsa, Regel. S. 

 fastigiata, Wall.). Closely allied to the foregoing; more 

 vigorous and upright, 6 ft. high, with terete branches 

 tomentose when young: Ivs. ovate to ovate-oblong, 



3666. Spiraea 



longigemmis. 

 (XJO 



acute at both ends, sharply serrate from the middle, 

 usually pubescent on the veins beneath, lJ^-3 in. long: 

 fls. white, % in. across, in l-4-in.-broad corymbs 

 terminal on upright, often very long branches: follicles 

 pubescent, diverging. July. Himalayas. S. pulchella, 

 Kunze (S. kumaonensis, Hort.), is supposed to be a 

 hybrid of this and the foregoing species; it combines 

 the broader corymbs of the latter with the brighter 

 color of the first species, therefore handsomer than 

 either parent; sometimes cult, as S. expdnsa rubra, but 

 there is also another hybrid of the same name. See S. 

 rubra in suppl. list. 



30. bullata, Maxim. (S. crispifdlia, Hort.). Dwarf 

 shrub, with strictly upright, brown, vinous branches: 

 Ivs. roundish-ovate to ovate, very short-petioled, 

 incisely serrate, thickish and bullate, almost glabrous, 

 grayish green beneath, ^-%in. long: fls. deep pink, in 

 small and dense corymbs lJ^-3 in. across. July, Aug. 

 Japan. Gt. 35:1216. 



31. japdnica, Linn. (S. callosa, Thunb.). Shrub, 4 ft. 

 high, with upright branches glabrous or puberulous 

 when young: Ivs. ovate to oblong-lanceolate, acute at 

 both ends or acuminate, doubly and incisely serrate, 

 pale bluish green and usually glabrous beneath, 1-4 in. 

 long: fls. small, pale to deep pink, in usually much- 

 compound and rather loose corymbs; sepals reflexed in 

 fr.: follicles glabrous, diverging with ascending styles. 

 June, July. Japan, China. A very variable species. 

 The variety most common in cult, usually under the 

 name S. callosa is var. F6rtunei, Rehd. (S. Fortunei, 

 Planch. S. cattdsa, Lindl., not Thunb.). Higher, with 

 quite terete branches: Ivs. 2-4 in. long, oblong-lanceo- 

 late, acuminate, sharply and doubly serrate, with 

 incurved, callous-tipped teeth, rugose above, bluish 

 white beneath: corymbs very compound, rather loose; 

 disk less developed, sometimes wanting. E. and Cent. 

 China. F.S. 9:871. B.M. 5164. B.H. 8 : 129. Hand- 

 some shrub with the young unfolding Ivs. of a pretty 

 purplish color and very large much-compound corymbs. 

 The Japanese forms grow less high, have smaller and 



broader, coarsely doubly dentate-serrate Ivs., not 

 rugose and less whitish beneath; the sts. are slightly 

 striped by the decurrent petioles and the infl. is less 

 compound. Other varieties of Chinese origin are the 

 two following recently intro. varieties. Var. acuminata, 

 Franch. Lvs. ovate-oblong to lanceolate, acuminate, 

 green and pubescent beneath, at least on the veins, 

 2-3^ in. long: fls. pink, in terminal corymbs 4-6 in. 

 across. Cent, and W. China. Var. ovalifdlia, Franch. 

 Lvs. oval to elliptic, acute, glabrous and glaucescent 

 beneath, 1H~3 in. long: fls. white, in corymbs 3-5 in. 

 across. W. China. Japanese forms little known in cult, 

 are var. pubescens, Regel, with the Ivs. pubescent 

 beneath and the corymbs pubescent, and var. glabrata, 

 Nichols. (S. glabrata, Lange), with ovate glabrous Ivs. 

 and bright pink fls. in glabrous corymbs. The following 

 are garden forms: Var. atrosanguinea, Zabel. Fls. 

 deep pink, in tomentose corymbs. Var. ruberrima, 

 Zabel. Fls. deep pink, in puberulous corymbs. Var. 

 macrophylla, Simon-Louis. Lvs. becoming 6 in. long, 

 bullate: corymbs small. Var. variegzlta, Hort. Lvs. 

 variegated with yellowish white. Most of the other 

 forms enumerated as varieties under this species are 

 hybrids. 



32. Margaritas, Zabel (S. japdnica x S. superba). 

 Shrub, 5 ft. high, puberulous: Ivs. ovate-elliptic to 

 elliptic, coarsely and often doubly serrate, pubescent on 

 the midrib beneath and pale green, 2-3 in. long: fls. 

 rather large, bright pink, in broad corymbs; sepals 

 spreading in fr. : follicles upright, glabrous, with upright 

 styles. July, Aug. Of garden origin. Handsome, very 

 free-flowering form. 



33. Foxii, Zabel (S. corymbbsa x S. japdnica). Simi- 

 lar to the preceding: branches more or less striped, 

 almost glabrous: Ivs. elliptic, doubly serrate, glabrous: 

 fls. whitish or pinkish, in large, puberulous corymbs; 

 styles spreading 



in fr. June, July. 

 R. H. 1900, p. 

 117. Of garden 

 origin. Less 

 desirable than 

 the preceding 

 hybrid. 



34. Bumalda, 

 Burvenich ( S . 

 japdnica x S . 

 albifibra. S. pu- 

 mila, Zabel). 

 Shrub, 2 ft. high, 

 rarely higher: 

 Ivs. ovate - lan- 

 ceolate, sharply 

 and doubly ser- 

 rate, glabrous, 

 2-3 in. long: fls. 

 whitish to deep 

 pink: follicles 

 diverging. July, 

 Aug. B.H. 17:

 416. Mn. 2, p. 

 24. G. C. III. 

 43:416. Cult, 

 in many differ- 

 ent forms, prob- 

 ably all of gar- 

 den origin. Two 

 of the best are 

 var. Anthony 

 Waterer, a very 

 free -flowering, 

 compact shrub 

 with bright crim- 

 son fls. in rather 3667. Spiraea albiflora.
