Varieties. Seringe has characterised four forms of this 

 species as follows : 



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

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

 Leaves lanceolate. Panicles consisting of ra- 

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

 lour. Bark of the branches yellowish. 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." 

 & S. s. 2 alpestris Pall. Fl. Ross. i. 

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

 S. alpestris Don's Mill. ii. 

 p. 5 1 9. (Our Jig. 5 1 6. ) A 

 small shrub. Leaves shorter 

 than those of S. s. carnea. 

 Branches very short. 



J* S. s. 3 paniculdta Willd. Sp. ii. p. 1055., Ait. Hort. Kew. ed. 2. iii. 

 p. 254. S. alba Ehrh. Beitr. vii. p. 137. (Our Jig. 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 Muhlenbcrgs Catalogue of North- American Plants.
