I Varieties. Seringe has characterised four forms of this 



species as follows : 



s S. s. 1 cdrnea Ait. Hort. Kew. ed. iii. p. 254., 

 Camb. Mon. (Eng. Bot., t. 1468. ; and our fig. 515.) 

 Leaves lanceolate. Panicles consisting of ra- 

 cemes more or less spicated. Petals of a flesh co- 

 lour. Bark of the branches \ellowish. This is the 

 form found wild in Britain : 

 whether it be indigenous or 

 not, botanists are not agreed. 

 Professor Henslow consi- 

 ders it " possibly introduced 

 by the agency of man." 

 36 S. s. 2 alpestns Pall. FI. Ross. i. 

 p. 36. t. 22., Camb. Monog. 

 S. alpestris Don's Mill. ii. 

 p. 519. (Our Z^. 516.) 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. (Our ,;%. 517.) 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 Muhlenberg's Catalogue of Korth- American Plants. 



516. S. . alpestris. 



518. S. J. latifolia.
