quantity of the seeds to the Arboretum. These were distributed among 
the best gardeners in the United States and in Europe, and as several 
thousand seedlings have been raised in the Arboretum nurseries, there 
seems now to be no reason why this beautiful plant should not become 
one of the chief beauties of spring gardens in regions too cold for the 
successful cultivation of any other Azalea with such large and beautiful 
flowers. The other Korean Azalea now in flower, R. poukhanense, is a 
smaller plant, rarely growing more than three feet high on the Pine- 
covered mountain slopes of the central part of the peninsula. It was 
first raised at the Arboretum from seeds also brought home by Mr. 
Jack, and its beautiful rose-lilac, fragrant flowers have been freely pro¬ 
duced here now every spring for several years. As it grows in the 
Arboretum this Azalea is a low, broad, round-topped shrub with its 
lower branches close to the ground. Roots are produced by such branches 
and would, if cut off and planted, probably soon produce flowering 
plants. Rhododendron poukhanense , although practically unknown as 
a garden plant beyond the limits of the Arboretum, deserves a place 
in all New England collections. These two Azaleas are now in bloom 
on Azalea Path where R. ( Azalea ) Kaempferi will soon be covered with 
its red or salmon-colored flowers, and R. ( Azalea) rhombicum has been 
in bloom during the past week. This is a hardy Japanese species with 
rose-purple flowers which are beautiful on plants so placed that the 
color of the flowers does not conflict with that of other Azaleas. 
Early flowering Viburnums. Two Viburnums have been flowering 
for several days, one from northeastern North America and the other 
from the sea cliffs of southern Korea. The American species, Vibur¬ 
num alnifolium, the Hobble Bush or Moosewood of cold wet northern 
woods, is one of the species with wide flat clusters of small flowers 
surrounded by a ring of showy white sterile flowers; the fruit is red 
when fully grown but finally becomes black, and the large leaves turn 
deep wine color in the autumn. The Korean species, Viburnum Carlesii, 
is fast becoming a popular plant in American gardens. The chief value 
of this shrub is in the white extremely fragrant flowers which are pro¬ 
duced in compact clusters and open from rose-pink buds. The buds do 
not all open at the same time and the mixture of pink buds with open 
flowers adds greatly to the interest and beauty of this shrub. 
The Asiatic Crabapples are beginning to bloom and Malus baccata var. 
mandshurica, M. micromalus and M. Halliana have been in flower for 
several days. The large white flowers of the first of these trees are 
more fragrant than those of any other Asiatic Crabapple in the col¬ 
lection which now contains all the species and many varieties and 
hybrids.
