buds have not been injured by the low temperature of recent winters. 
There is every reason to believe therefore that it will be possible to 
cultivate R. Schlippenbachii anywhere in the northern states where the 
soil is not impregnated with lime. If this prediction proves true New 
England will be able to add to its gardens one of the most beautiful 
of all the Azaleas. This plant, unfortunately, is still rare in gardens. 
Although known to Russian botanists as early as 1872, it did not reach 
England until twenty years later when the late J. H. Veitch sent to 
London a plant which he had found in a nursery garden near Tokyo. 
The plants in the Arboretum were raised here from seeds brought by 
Mr. Jack from Korea, and at different times a few plants have reached 
this country from the Yokohama Nursery Company. Fortunately Mr. 
Wilson during his journey in Korea in 1917 secured a large quantity of 
the seeds of this Azalea; this has been widely distributed by the Ar- 
boretum in the United States and Europe and has produced several 
thousand plants. There is reason to hope, therefore, that this loveliest 
of the hardy Asiatic Azaleas will become a common inhabitant of north- 
ern gardens. 
Broad-leaved Evergreens. In addition to the two Rhododendrons with 
evergreen 'leaves mentioned in the first Bulletin of the present year 
there are only two broad-leaved evergreen plants which flower here in 
April and are perfectly hardy. They are Andromeda Jiorihunda and the 
Leather Leaf (Chamaedaphne cdlyculata) . The former is a native 
of the high southern Appalachian region and has been known in gardens 
for at least a century; it is not, however, often seen in those of New 
England in which, with the exception of the Laurel (Kalmia) and a 
few Rhododendrons, it is the handsomest evergreen shrub which can 
be successfully grown. It is beautiful, too, throughout the year for the 
dark green leaves, although not large, are always lustrous; the flower- 
buds, which are formed in the autumn, are large, nearly white, and 
conspicuous during the winter, and open into bell-shaped white flowers 
arranged in short terminal clusters which cover the plants during several 
weeks and are not injured by spring frost. This Andromeda under fav- 
orable conditions sometimes grows five or six feet high, with a diame- 
ter often greater than its height. It is a good subject to use as a 
single specimen or on the margin of beds of taller growing evergreens, 
like Rhododendrons or Kalmias, and no broad-leaved evergreen is better 
suited for the decoration of large rock gardens. The related species 
from Japan, Andromeda japonica, is a larger plant, sometimes tree- 
like in growth in its native country, with larger and more beautiful 
flowers which unfortunately in this climate are generally ruined by spring 
frosts. The Leather Leaf is an inhabitant of cold, wet northern bogs 
which it sometimes covers almost to the exclusion of other plants. It 
is a dwarf shrub with small obtuse scurfy leaves and small, white, ax- 
illary flowers. The Leather Leaf is a less beautiful plant than Andro- 
meda Jioribunda but it is a hardy, broad-leaved evergreen and therefore 
valuable in a region where so few such plants can be successfully grown. 
Although naturally a bog plant, the Leather Leaf flourishes when planted 
in drier soil and the plant in the Shrub Collection and its dwarf form 
(var. minor) are unusually full of flowers this spring.
