Spec. Char., §c. Leaves oblong, glaucous beneath. Corollas ovate, flesh- 
coloured, or pale red. Segments of calyx ovate, spreading, white, some- 
times tipped with red. (Don’s Mill. iii. p.829.) A i 
native of the northern countries of Europe, on turfy 
bogs; as of Russia, Sweden, Denmark, Switzerland, 
Germany, Britain, &c.; of North America, in Canada 
and Labrador, Bay of St. Lawrence, &c., in bogs, and 
on the borders of mountain lakes ; and in New York 
and Pennsylvania. In Britain, in mossy bogs in the 
mountainous parts of England and Ireland, and the 
lowlands of Scotland. It is cultivated in gardens, in 
moist peaty soil, and it is only in such soil, and in 
an open airy situation, that it can be preserved for any 
length of time. Like all the species of this order, it is propagated by layers, 
and sometimes by division. It flowers from May to September. This 
species and the following are sometimes admitted into ericetums, as being 
nearly allied to heaths, but in our opinion very improperly, for two reasons : 
first, because the leaves are so much broader than those of any heath, that, 
both in a general and a botanical point of view, they destroy the unity of 
the whole or scene; and, secondly, because, to grow these two andromedas 
properly, they require to be planted in much moister peat than is suitable 
for any species of heath. 

Varieties. The following varieties, the first of which may be considered as 
the normal form of the species, are enumerated in Lodd, Cat., ed. 1836.

when it was introduced is uncertain.
