are, however, easily propagated and a demand for them will in time pro- 
duce a supply. The list contains the names of eighteen of “the best” 
new shrubs; it might easily be increased to a hundred for there is a 
large number of new or little known shrubs now growing in the Ar- 
boretum which American garden-makers unfortunately neglect. The 
plants selected today are:— Hammamelis mollis, Prinsepia sinensis, 
Corylopsis Gotoana, Amelanchier grandiflora, Forsythia intermedia 
spectahilis, Cotoneaster hupehensis, C. racemijlora soongorica, C. nitens, 
C. multijlora calocarpa, Rosa Hugonis, Neillia sinensis. Rhododendron 
Schlippenbachii, R. japonicum, Berberis Vernae, Syringa Sweginzowii, 
Spiraea Veitchii, Philadelphus purpurascens, and Evonymus planipes. 
Like the other Witch Hazels of eastern Asia, Hammamelis mollis 
blooms in the winter and the flowers are not injured by the severe cold 
to which they are subjected in the Arboretum. This plant has hand- 
some foliage and larger and more brightly colored flowers than the 
other Witch Hazels, and is invaluable for the decoration of winter gar- 
dens. Prinsepia sinensis is considered here the best shrub the Arbor- 
etum has obtained from Manchuria. It is valuable for its perfect hard- 
inesss, the fact that its dark green leaves unfold before those of any 
other shrub in the Arboretum, with the exception of those of a few 
Willows, and for its innumerable clear yellow flowers which open be- 
fore the leaves are fully grown. The stems of this shrub are armed 
with stout spines and it should make a good hedge plant. Corylopsis, 
which is an Asiatic genus related to the Witch Hazels, has handsome 
yellow, early spring flowers in drooping clusters which appear before 
the leaves. There are several Japanese and Chinese species in the Ar- 
boretum but only the Japanese C. Gotoana has been uninjured here 
by the cold of recent years, and it is the only species which can be de- 
pended on to flower every year in a Massachusetts garden. The For- 
sythia of the list is still the handsomest of the varieties of F. inter- 
media which is the general name of the hybrids betweeen F. suspensa 
Fortunei and F. viridis. This variety was raised in a German nursery 
and is the handsomest of all the Forsythias now known in gardens. 
Amelanchier grandiflora is believed to be a hybrid between the two 
arborescent species of the eastern United States, A. canadensis and 
A. laevis, and is by far the handsomest of the Amelanchiers in the 
large Arboretum collection of these plants. It came here from Europe 
but what is believed to be the same hybrid has been found in several 
places in the eastern states. The four Cotoneasters in the list are per- 
haps the handsomest of the twenty odd species introduced by Wilson 
from western China. They are all large shrubs of graceful habit, and 
have white flowers and red fruits with the exception of C. nitens which 
has red flowers and black fruit. In recent years the Arboretum has 
made few more important introductions for American gardens than the 
Chinese Cotoneasters. Although no longer a "'ne^M planP^ Rosa Hugonis 
is included in this list because it is not only the handsomest of the 
Roses discovered in China during the last quarter of a century, but in 
the judgment of many persons it is the most beautiful of all Roses 
with single flowers. Fortunately for American garden-makers the 
value of this Rose is appreciated by a few American nurserymen from 
whom it can now be obtained. The introduction of Neillia sinensis 
made it possible to add to the Arboretum collection a representative of
