to which it is able to attach itself firmly. Short lateral branchlets 
are developed from the stems; these bear the terminal flower-clusters 
which are thus brought out from the general surface of the vine and 
give to the covering of the wall a loose and attractive appearance. 
Such a plant can now be seen in flower on the Administration Building. 
Indigoferas. Indigofera Kirilowii is flow r ering in the Shrub Collec- 
tion and on Hickory Path near Centre Street. It is a low shrub which 
spreads rapidly into a broad mass, and produces during several weeks 
racemes of large pure pink flowers. Introduced a few years ago into 
the Arboretum by Mr. Jack who found it in Korea, it has proved one 
of the best plants of its class. Near it on Centre Street Indigofera 
amblyantha is also in flower. It is a plant of entirely different habit, 
with slender stems, small leaves, and axillary clusters of small rose- 
colored flowers which continue to appear during two or three months. 
This is one of the most beautiful of the small shrubs introduced by 
Wilson from western China where he found it growing on river cliffs 
in Hupeh at altitudes up to six thousand feet above the sea. Two other 
species of this genus are established on Azalea Path near its entrance 
from the Bussey Hill Road, I. Gerardiana, a native of the Himalayas, 
and I. decora from southern China. These two plants, although they 
are killed back to the ground every winter, send up new stems and 
flower profusely every year. I. decora, which is just in bloom, is a 
handsome plant with racemes of large white flowers. 
Late Bush Honeysuckles. In the Shrub Collection two of the latest 
of these plants are in flower, and are beautiful now and will be still more 
beautiful later in the season when more of the fruit is ripe. They are 
Lonicera Ledebourii from the Pacific coast region and L. involucrata, 
var. serotina from the mountains of the interior of the continent. The 
long slender flowers of these plants are bright yellow more or less 
tinged with red and surrounded by large, leaflike, dark red cups which 
remain under the large, black, lustrous fruit. These plants remain in 
bloom for a long period, and flowers and ripe fruit can now be found 
on them. This group of Honeysuckles, of which there are several 
forms, contains some of the hardiest and most beautiful garden shrubs 
which have been brought into the Arboretum from western North 
America, a region which has produced few plants which are hardy in 
this climate. 
Two Andromeda-like Plants. Leucothoe Catesbaei and Lyonia mari- 
ana are now in flower. The former is an evergreen with long, spread- 
ing and arching stems clothed with handsome long-pointed leaves, and 
small clusters of axillary white flowers; it is a native of the southern 
Appalachian region and one of the hardiest and most desirable of the 
broad-leaved evergreen shrubs which can be grown in this climate. It 
requires moist soil and a shady position. It can be seen in large 
numbers along the brook and in the small ravine at the base of Hem- 
lock Hill. Lyonia mariana is a smaller shrub with deciduous leaves 
and white, racemose flowers borne on leafless shoots. This plant is 
common in the eastern states from Rhode Island southward, and when 
cultivated is not particular about soil or situation. There is a mass of 
these plants now in full bloom on the right-hand side of the Meadow 
Road in front of the Horsechestnut Group.
