cent branchlets : but the one has deep red flowers, and was received 

 from Aberdeenshire ; and the other, which was received from Arran, 

 has white flowers, that appear later than those of the other varieties. 

 The first may be called C. v. 11 dtro-nlbens, and the second C. v. 12 

 serotina. 



Very ornamental, either as detached bushes, or as edgings to beds and 

 borders, in sandy or eaty soil. 



ii. Andromedeas. 



All the species are propagated by layers, and some of them also by divi- 

 sion, though most of them might, doubtless, be rooted in sand from the points 

 of the growing shoots, as in the preceding section ; but layers soonest make 

 saleable plants. They all require a soil more or less peaty, and a situation 

 cool, open, and moist, rather than dry and airy. Most of the genera are of 

 comparatively short duration, though some species of Andromeda and A'v- 

 butus attain an almost tree-like size, and endure many years.
