and fruit in drooping clusters, bright red at first when fully grown 
and dark blue or nearly black at maturity. This is one of the hand- 
somest of the American Viburnums but it has proved a difficult plant 
to establish here, although in other Massachusetts gardens it has grown 
better than it has in the Arboretum where, however, it at last appears 
to have become accustomed to its surroundings. In Japan there is a 
Viburnum ( V. furcatum) closely related to and very much like the 
Hobble Bush, from which it chiefly differs in the shorter stamens which 
are hardly more than half the length of the corolla, and in the deep 
groove on the ventral side of the stone of the fruit. Viburnum fur- 
catum in Japan, where it grows from the mountains of central Hondo 
to Saghalin, is a shrub sometimes ten or twelve feet high with smooth, 
red-brown branches and branchlets. Like its American relative, this 
Japanese Viburnum has proved difficult to establish, but a plant is now 
opening its flowers here, two or three days later than those of V. alni- 
folium, and for the first time in the Arboretum. In a few days the 
flowers of another early-flowering species, V. Carlesii, will open. This 
shrub has been found only among seashore rocks in two localities in 
Korea and has already become a popular garden plant in this country 
and Europe. Its real value is found in the white, extremely fragrant 
flowers which are arranged in small compact clusters and open from 
rose-colored buds. As the buds in the cluster do not all open at once 
the pink buds among the white flowers add to the beauty of this shrub 
in early spring. Late in the autumn the small dull olive green leaves 
turn dark rich wine color. 
Early Azaleas. The first Azalea to open its flowers this spring is 
the Korean Rhododendron (all Azaleas are now called Rhododendrons) 
poukhanense. This Azalea, which is a common plant on the bare moun- 
tain slopes in the neighborhood of Seoul, was first raised at the 
Arboretum in 1905 from seeds collected in Korea by Mr. J. G. Jack. 
As it grows here this Azalea is a low, wide, compact bush which never 
fails to cover itself with its large, rose-pink flowers. Some persons do 
not find this color pleasing, but the flowers of no other Azalea in the 
collection have such a strong and pleasant fragrance. There is a con- 
siderable number of these plants in the bed on the upper side of Azalea 
Path. The plants ripen good crops of seeds; the seedlings are not diffi- 
cult to raise and there is no reason why this plant should not be more 
common in gardens than it is at present. The flower-buds of Rhodo- 
dendron {Azalea) Schlippenbachii will open a few days later than 
those of R. poukhanense. This Azalea grows on the exposed grass- 
covered cliffs of the east coast of Korea as a low bush with branches 
clinging to the ground and far northward as a tall shrub sometimes twelve 
or fifteen feet high under trees in open or dense forests. It grows 
further north than other Asiatic Azaleas, and only the North American 
Rhodora reaches a higher latitude. The flowers of this Azalea appear 
before the leaves and are pale pink marked at the base of the upper 
lobes of the corolla with dark spots and are about three inches in diam- 
eter. There can be little doubt of the hardiness of this plant, for in 
Korea it grows to its largest size where the winter temperature often 
falls to 30° below zero Fahrenheit; and in the Arboretum the flower-
