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

 fig- 4*8., has its pink flowers nearly twice as large as those of the 

 species ; and is a very ornamental free-growing shrub. It was raised 

 by Messrs. Loddiges from seeds sent to them from Kamtschatka 

 in 1826, by M. Busch. 



Description, §c. S. salicifdlia, according to Pallas, grows as 

 high as G ft., in favourable situations, in Russia and Siberia ; 

 but in England it is seldom found higher than 4 ft. It 

 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 4 ft. in one 

 season, and flower. These suckers are produced in such 

 abundance, 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 has been in 

 cultivation in England since 1665; but whether it was in- 

 troduced from some other country, or from localities where 

 it is said to be found wild, is uncertain. According to Dr. 

 Hooker and G. Don, it is wild in several parts of Scotland. 

 Sir J. E. Smith believes it to be wild at Hafod, in Cardigan- 

 shire; the situation in which it grows there being perfectly like its native 

 swamps in the south of Europe. 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. It will grow with more or 

 less luxuriance, according to the degree of richness, and 

 moisture of the soil.

Spec. Char., Sfc. 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. S8J 

 The leaves are ovate and serrated, the latter partly doubly " 



Lobes of the calyx triangular and deflcxed. Carpels 

 divaricate. A native of Canada, and of mountainous 

 situations in the west of North America. (Dec. Prod., ii.
