tend itself through the deserts of Mogul Tartary to 
China and Tibet. It grows very commonly in the 
pine forests ; and in some parts in such profusion, 
and so densely, as to make whole tracts appear a 
sheet of purple in April and May, the period when 
it is in blossom.’ It may be further stated on the 
same authority that it is almost peculiar to the 
subalpine tracts of eastern Asia ; and is most a- 
bundant about Baikal, assuming, as it is found 
more northerly, slender flowers and narrow leaves. 
The leaves are sometimes used as a substitute for 
those of the Tea-tree. The new foliage is put on 
after the departure of the bloom. 
R hododendron Dauricum is not unfrequently kept 
in the greenhouse, where it forms a handsome 
plant, and its flowers are seen to advantage. This 
is not always the case under full exposure, from 
their being met by severe frosts in the early part 
of spring. The plant will, however, be looked 
upon with most interest as a hardy shrub, and al- 
though it may be unnecessary, in respect to its 
safety, to afford it any protection, still the trouble 
of giving it an occasional covering to preserve the 
flowers, will be amply repaid by their additional 
beauty. Hoops tied to stakes, and covered with a 
mat would be portable and efficient. 
Good peat soil is a requisite that cannot, we 
believe, be dispensed with in the culture of this 
plant, although it is not indispensable with all spe- 
cies of Rhododendron. May be increased by cut- 
tings of the young wood, which should be struck in 
sand, under a bell-glass, submitted to a moderate 
heat.
