Willd. Enum. p. 540., Don's Mill. ii. p 520. (Wats. Dend. Brit., 

 t. 66.; and our Jig. 518.) Leaves ovate-oblong. Petals white. Bark 

 of branches rather reddish. 



tt S. s. 5 grandiflora ; S. grandiflora Lodd. Bot. Cab. t. 1988., and our 

 fig. 519. ; has its pink flowers nearly twice as large as those of the 

 species ; and is a very ornamental free-growing shrub. Raised from 

 seeds sent from Kamtschatka, in 1826. 



& S. s 6 taurica. S. taurica Hort. An upright shrub, 8 ft. to 10 ft. high, 

 tolerably distinct, and coming into flower* before any other variety. 

 Hort. Soc. Garden. 



Other Varieties or Synonymes. The following kinds, in Messrs. Loddiges's 

 collection and in that of the Hort. Soc., are either varieties of, or identical 

 with, S. salicifolia : S. canadensis, S. wrticaefolia, S. laciniata, S. chamaedri- 

 folia, S. lanceolata, S. carpinifolia, S. reflexa, S. incarnata. 



This species sends up numerous straight rod-like stems, and these and the 

 lateral branches terminate in large, conical, spiked panicles, of pale red, or 

 flesh-coloured, flowers. In deep moist soils, a sucker will attain the height of 

 4ft. in one season, and flower. These suckers are produced in such abun- 

 dance, that, in order to keep the shrub in a -vigorous state, they ought to be cut 

 down when they have flowered two years, in the same manner as is practised 

 with raspberries ; and the entire plant ought also to be taken up every three 

 or four years, and separated ; otherwise the old shoots are apt to die, and 

 render the bush unsightly. It is one of the hardiest of garden shrubs, and is, 

 also, very beautiful, from its long spicate panicles full of light feathery-looking 

 flowers.

Spec. Char., fyc. Branches pubescen t at the apex, as well as 

 the peduncles and calyces. Sepals reflexed. Leaves elliptic, 

 coarsely and unequally serrated towards the apex, glabrous, 

 the same colour on both surfaces; panicle crowded with 

 flowers, oblong, obtuse. Flowers small. Stamens twice the 

 length of the corolla ; ovaries 5, glabrous. (Don's Mill.) An 

 erect shrub. North America, on the west coast. Height

 June and July.

Spec. Char., $c. Nearly all the parts of this plant are more 

 or less clothed with tomentum, the under surface of the 

 leaves most so. The tomentum upon the stem and pe- 

 duncles, and perhaps elsewhere, is of a reddish colour. 

 The leaves are ovate and serrated, the latter partly doubly 

 so. Lobes of the calyx triangular and deflexed. Carpels 

 'divaricate. (Dec. Prod.) An erect shrub. Canada, on 

 mountains. Height 2ft. to 3ft. Introduced in 1814. 

 Flowers white; June and July. Capsule reddish ; 1'ipe in 

 September. 



This species, or subspecies, in its mode of growth, re- 

 sembles S. salicifolia ; but differs from it in having rather 

 smaller and more deeply serrated leaves, which are very to- 

 mentose beneath. The flowers are much smaller, and of a 

 deeper red.
