CHAP. XLII. ROSA CEE. SPIRA‘A. 729 
% 18. S. BE’LLA Sims. The beautiful Spirea. 
Identification. Sims Bot. Mag., t. 2426.; Don’s Prod, Fl. Nep., p. 227.; Dec. Prod., 2. p. 54S 
Don’s Mill., 2. p. 518. 
Engravings. Bot. Mag., t. 2426. ; and our jig. 440. 
Spec. Char., §c. Stems erect, branched, gla- 440 
brous, and reddish. Leaves ovate, acute, 
sharply serrated, whitishly tomentose on the 
under surface. Flowers pretty, rose-coloured, 
and laxly disposed. Lobes of the calyx de- 
flexed. (Dec. Prod., ii. p. 542.) A native of 
Nepal; resembling, in its mode of growth 
and foliage, S. salicifolia; but being very 
distinct from that species in its inflo- 
rescence ; the flowers of S. salicifolia being 
produced ina spiked panicle, and those of S. 
béllainacorymb. It was introduced in 1820, 
and grows to the height of 3ft. or 4 ft., 
producing its beautiful rose-coloured flowers 
in May and June. This species isas hardy, 
and as easily propagated, as that very com- 
mon shrub, S. salicifolia; as, like that spe- 
cies, it emits, from under the soil, rooting sprouts, or suckers, which, when 
their leaves begin to turn yellow, at the end of their season of growth, may 
be detached, and planted separately, as distinct plants; and it is, at the 
same time, one of the most beautiful of the genus. No garden, however 
small, ought to be without it. Plants are 1s. each. 

§ iii, Spiradria Ser. 
Sect. Char. Ovaries distinct. Torus with its base connate with the tube of 
the calyx; its tip separate. Carpels not inflated. Inflorescence a panicle. 
Leaves serrate, without stipules. (Dec. Prod., ii. p. 544.) 
% 19. S. saticiro‘Lia L. The Willow-leaved Spiraea, 
Identification. Lin. Sp.,'700.; Camb. Monog.; Dec. Prod., 2. p. 544, 
Synonymes. Spire’a frutex Hort.; Bridewort, Queen’s Needle-work. 
Engravings. Gmel. FI. Sibir., 3. t. 49. ; Eng. Bot., t. 1468 ; and our fig. 443. 
Spec. Char., §c. Stem and peduncles glabrous, Leaves lanceolate, serrated, 
and, more or less, doubly so; glabrous. Lobes of the calyx triangular, 
spreading. Carpels glabrous. (Dec. Prod., ii. p. 544.) A native of 
Siberia, Tartary, and Bohemia ; also of Canada, and, perhaps, of Britain. 
Varieties. Seringe has characterised four forms of this species, as follows :— 
% S.s. 1 cdrnea Ait. Hort. Kew., ed. iii, p. 254., Camb. Monog., Eng, 
Bot., t.1468., and our jig.443.—Leaves lanceolate. Panicles consist- 
ing of racemes more or less spicated. Petals of a flesh colour. 
Bark of the branches yellowish. This is, by the reference to Eng, 
Bot. cited, the form which is found wild in Britain: whether it be 
indigenous or not, botanists are not agreed. Professor Henslow 
has referred it (Catal. of Brit. Plants) to his class “ Possibly intro- 
duced by the Agency of Man.” 
% S. s. 2 alpéstris Pall. Fl. Ross., i. p. 36. t. 22., Camb. Monog.; S. 
alpéstris Don’s Mill., ii. p. 519.— A small shrub. Leaves shorter 
than those of S. s. carnea. Branches very short. 
& S.s.3 paniculata Willd. Sp., ii. p. 1055., Ait. Hort. Kew., ed. 2. iii. 
p. 254. S. alba Ehrh. Beitr., vii. p. 137. Leaves ovate-oblong. 
Petals white. Bark of the branches red. It is likely that this is 
also the S. alba of Miller, of Wats. Dend. Brit., t. 133., and of 
Mulhlenberg’s Catalogue of North American Plants.
