in the Minn valley. C. hupehensis is perhaps even more beautiful as 
a flowering plant than C. multiflora, for although the white flowers 
are smaller they are less covered by the smaller leaves. It is a large, 
wide-spreading shrub with very slender arching stems and branches 
which are now so covered with flowers that from a distance it is hard 
to realize that it is a Cotoneaster and not a Spiraea. The fruit is 
bright red and very beautiful. C. foveolata is a large vigorous plant 
with stout arching stems from six to ten feet high, large thin leaves 
dark green and lustrous above and pale below with prominent veins 
deeply impressed on the upper surface. The flowers are small, globose 
and red,, in compact clusters, on stalks much shorter than the leaves 
by which they are a good deal hidden. The fruit is black and lustrous. 
The greatest beauty, perhaps, of this plant is in the autumn color of 
the leaves, for after the leaves of most American shrubs have fallen 
those of this Chinese Cotoneaster change to brilliant shades of orange 
and red. There are few more beautiful autumn plants in the Arbore- 
tum. Something like C. foveolata in the size and color of the flowers 
and in the shape of the smaller leaves is a variety of the north China 
C. acutifolia from the borders of Tibet'fvar. villosula) which is also in 
flower. This is a dwarfer and more compact shrub than C. foveolata, 
with black fruits and bright autumn colors. Another set of these 
plants is distinguished by small dark green leaves, small red flowers 
and red fruit. The best known of these, C. horizontalis, has been in 
cultivation now for several years and is not rare in European gardens. 
It is a low shrub with wide-spreading branchlets which when trained 
against a wall grow several feet tall, but untrained form a dense mat 
two or three feet high and sometimes six or eight feet in diameter. 
In this climate the leaves remain on the branches without change of 
color until early winter, but in milder climates do not fall until the 
spring. The best specimen of this handsome plant in the Arboretum 
is on Hickory Path near Centre Street. C. divaricata , which is also 
in flower, is a larger plant with wide-spreading stems forming a rather 
open head, and bright red fruit. From this the related C. nitens, 
which is a smaller shrub, differs chiefly in its more compact habit and 
reddish black fruit. Distinct with prominent stems forming mats only 
a few inches high are C. adpressa and C. microphylla. These are 
useful little plants for the rock garden and for the edging of garden 
walks. Several of the Chinese Cotoneasters are in the general Shrub 
Collection and on Hickory Path, but the best specimens are in the 
Chinese Shrub Collection on the southern slope of Bussey Hill where 
these plants have been growing for four years in an exceedingly ex- 
posed position and without protection. 
Flowering Ashes. This is the common name for a group of Ash 
trees (Fraxinus) with elongated white petals which make the flowers con- 
spicuous. They are natives of southern and southeastern Europe, the 
Himalayas and western and northern China. A shrubby species, F. 
dipetala, is common in California, and two Mexican species extend 
into the territory of the United States, one in southern Texas and 
the other in Arizona where it ranges as far north as the rim of the 
Grand Canon of the Colorado River. The type of the group, Fraxinus
