uable shrubs of recent introduction. There are now many good speci- 
mens of these Cotoneasters on Bussey Hill and they deserve the atten- 
tion of all lovers of hardy plants, especially Cotoneaster divaricata, 
C. foveolata and C. Dielsiana, the leaves of which turn brilliant colors, 
and the different forms of C. horizontalis, low shrubs with wide-spread- 
ing nearly prostrate branches. These have small lustrous leaves which 
in this climate do not fall before Christmas, and small red berries. No 
shrubs are better suited for the decoration of the rock garden. 
Among the American Hawthorns which show their greatest beauty 
in November may be mentioned Crataegus cordata , C. nitida and C. 
persistens. The first of these plants, the so-called Washington Thorn, 
is a narrow, slender tree, which sometimes attains the height of twenty 
or thirty feet. The flowers are small, creamy white, and do not open 
here until nearly the middle of June, and the small, scarlet, shin- 
ing fruits, which ripen late in October, remain on the trees without 
much change of color until the spring. As the fruit begins to show 
its bright color the small triangular leaves turn to shades of orange 
and scarlet. Crataegus nitida is a native of the bottom-lands of the 
Mississippi opposite the city of St. Louis; it is a large tree with slightly 
spreading pendulous branches forming a large, open, round-topped head. 
The leaves are narrow, long-pointed and very lustrous; the flowers are 
pure white, of medium size, and produced in numerous clusters which 
cover the upper side of the branches. The scarlet drooping fruit, which 
is also of medium size, ripens late just as the leaves turn orange and 
scarlet. This is one of the handsomest of the American Hawthorns 
and has grown to a large size in the Arboretum. Crataegus persistens 
retains its leaves, which are now as green as they were in mid- 
summer, after those of all other Hawthorns have fallen, and the 
crimson fruit remains on the branches until spring, making this tree 
in winter the most conspicuous of the deciduous-leaved plants hardy in 
New England. It resembles in the shape and in general appearance of 
the leaves some of the Cockspur Thorns of eastern North America. 
Raised many years ago at the Arboretum from seeds received from the 
Paris Museum, its native country is still unknown. The largest plant 
of this tree in the country, and the type of the species, can be seen 
among several large Hawthorns at the foot of the bank on the path- 
way near the Forest Hills entrance to the Arboretum, where it is now 
the only plant with perfectly green leaves. 
The only shrub now in flower in the Arboretum is the Witch Hazel 
of the northern states ( Hamamelis virginica) which is covered with 
its yellow flowers. 
These bulletins will now be discontinued until spring. 
The Arboretum will be grateful for any publicity 
given these Bulletins.
