it can only be propagated by grafting Magnolia cordata is rare in col- 
lections. 
Some of the most beautiful and interesting shrubs now in flower will 
be found among the Bush Honeysuckles. The decorative value of some 
of these can best be seen in the grass border by the Bussey Hill 
Road, opposite the Lilac Group, where several of these shrubs have 
been so planted that they have abundant space for full development and 
can show all their beauty of foliage, flowers and fruit. In the Shrub 
Collection there are a large number of these plants, and others can be 
found in the supplementary collection in the border on Linden Path in 
the rear of the group of Linden trees. In the Shrub Collection sev- 
eral interesting species are in flower or will soon be in flower. Atten- 
tion is called to Lonicera syringantha and its variety Wolfii from west- 
ern China, with purple fragrant flowers, and to L. tibetica. Two 
charming plants in this collection are L. amoena and L. amoena Arnold- 
iana, the latter a product of the Arboretum. They are garden hybrids, 
with slender pink flowers, of the Tartarian Honeysuckle, with L. Korol- 
kowii , a species of central Asia. Other Honeysuckles now in bloom 
which should be examined are L. bella , a large and vigorous hybrid of 
L. Morrowii with the Tartarian Honeysuckle, L. minutijlora , remark- 
able in the beauty of its brilliantly colored fruits, L. notha , a hybrid 
of the Tartarian Honeysuckle with L. Ruprechtiana of eastern Siberia, 
L. minutijlora from central Asia, and the slender and graceful L. coeru- 
lea graciliflora with its beautiful drooping flowers. Of the shrubs in- 
troduced by the Arboretum into New England gardens none is now more 
generally cultivated or has proved more valuable than L. Morrowii 
from northern Japan. This in cultivation here is a broad high bush 
with wide-spreading branches clinging close to the ground. The pale 
blue-green leaves are pleasant in tone, and the yellow flowers are pro- 
duced in the greatest profusion. This remarkable shrub, which has 
been largely planted in several of the Boston parks, appears to grow 
here more vigorously than it does in its native country. 
On Azalea path the red-flowered Rhododendron ( Azalea ) Kaempferi 
is in flower. There are masses of this plant on both sides of the lower 
end of this path and between the Hemlocks and the Laurels at the 
northern base of Hemlock Hill. The shade and coolness of this position 
suit this inhabitant of the high mountains of Japan, and it flowers 
later here than on Azalea Path and the flowers remain longer in good 
condition. These flowers, in front of the dark background of Hemlocks, 
make one of the most brilliant shows of the Arboretum season. 
The earliest of the American Rhododendrons to flower, R. carolini- 
anum, is opening its flowers in the collection at the base of Hemlock 
Hill. This is a southern plant with handsome, very dark green leaves 
and small clusters of bright pink flowers. It grows at a considerable 
elevation on the Appalachian Mountains and although it was known in 
England and recognized as a distinct variety as early as 1810, it was 
afterwards confused with another southern species, R. punctatum and 
entirely lost sight of; and it is only recently that a comparison of the 
two plants in cultivation has shown the differences between them. It 
is perfectly hardy and a valuable garden plant. R. punctatum is a 
plant of lower altitudes with smaller leaves and flowers; it blooms sev- 
eral weeks later and is a less valuable plant. 
The Arboretum will be grateful for any publicity 
given these Bulletins.
