Varieties. Seringe has characterised four forms of this 
species as follows : — 
gs 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 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. alpéstris Don’s Mill. ii.

smallshrub. Leaves shorter 
than those of S. s. carnea. 
Branches very short.

that this is also the S. alba of Miller, of Wats. Dend. Brit. t. 133., 
and of Muklenberg’s Catalogue of North-American Plants.
