This very beautiful shrub was discovered by Douglas, in 
British Columbia, and is common on the banks of the Oregon 
and straits of St. Juan de Fuca; it has also been found in Ca- 
lifornia by Lobb, n. 341, under which number another species 
has been sent by the same collector, of which we shall give a 
figure shortly. It was first raised at the Royal Botanic Gar- 
dens of Glasgow, from Douglas’s seeds, and since from those of 
Lobb. It flowered this year in the Royal Gardens, Kew, and 
in that of Mr. Noble, of Bagshot, to whom we are indebted for 
the specimen here figured, together with those of 8. Nobleana and 
S. callosa, wh ill shortly be figured, and under which will 
be found som her remarks upon this. :
