species; it combines the broader corymbs of the latter 

 with the brighter color of the first species, therefore 

 hpiidsomer than either parent; sometimes cult, as *S'. 

 expansa rultra, but there is also another hybrid of the 

 same name. See S. rubra in suppl. list. 



26. buUata, Maxim. {S. crispifblia, Hort.). Dwarf 

 shrub, with strictly upright brown, villous branches: 

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

 cisely serrate, thickish and bullate, almost glabrous.

 glabrous or puberalous when young: ivs. ovate to 

 oblong-lanceolate, acute at both ends or acuminate, 

 doubly and incisely serrate, pale bluish green and usu- 

 ally glabrous beneath, 1-4 in. long: fls. small, pale to

 Handsome shrub, with the young unfolding Ivs. of a 

 pretty purplish color; usually much cult, under the 

 name ^S". caUosa. 



Var. F6rtunei, Rehd. (,S'. Portiiiicl, Planch. S. caj- 

 Jdsa, Lindl., not Thunb.). Higher, with quite terete 

 branches: Ivs. 2-4 in. long, oblong-lanceolate, acumi- 

 nate, sharply and doublj' serrate, with incurved, callous- 

 tipped teeth, rugose above, bluish white beneath: 

 corymbs very compound, rather loose; disk none or 

 very minute. This seeius to be the C'hinese form; the 

 Japanese form grows less high, has smaller and broader, 

 coarsely doubly dentate-serrate Ivs., not rugose and 

 less whitish beneath; the stems are slightly striped by 

 the decurrent pietiole.s tmd the inflorescence is less 

 compound. Var. atrosanguinea, Hort. Pis. deep pink, 

 in tomentose corymbs. Var. rub^rrima, Hort. Fls. 

 deep pink, in ptiberulous corymlis. Var. macrophylla,

 small. Var. glabrita, Xiclnds. ( ,S'. ijliibrUfa, Lange).

 pink, in glabrous corymbs. Var. pubescens, Regel. Lvs. 

 pubescent on the veins Vieneatb : corymb tomentose. 

 Most of the other forms often enumerated as varieties 

 are hybrids of this sp>ecies. 



28. Margaritae, Zabel (S.Japonica x superha). Shrub, 

 5 ft. high, puberulous: lvs. 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 

 iu fruit: follicles upright, glabrotts, with upright styles: 

 July, Atig. Of garden origin. — Handsome, very free- 

 flowering form. 



29. Fbxii, Zabel (6'. rnrytiihnxa y Jap<h(ica). Similar 

 to the preceding; branches more <">r less striped, almost 

 glabrous: lvs. elliptic, doubly serrate, glabrous: fls. 

 whitish or pinkish, in large, pul;)eruloas corymbs; styles 

 spreading in fruit. June, Jul5\ Of garden origin.— 

 Less desirable than the p»receding hybrid. 



30. Bumilda, Burvenich (S. JapSniea. y. alhiflora. 

 S. pitmila, Za))el). Shritli, 2 ft. high, rarely higher: 

 lvs. oyate-hmceolate, sharplj^ and doubly serrate, gla-

 garden origin. One of the best is var. Anthony Waterer,
