southern Appalachian foothill region and westward to Missouri, and has 
occasionally become naturalized in the middle Atlantic states from West 
Chester County, New York, to Delaware. It is a tree sometimes thirty 
feet high, with erect branches, small, nearly triangular, shining leaves 
which turn bright scarlet in the autumn, small, dull white flowers in 
small compact clusters, and small scarlet fruit which remains on the 
branches until late spring. The late flowers, the brilliancy of the 
autumn foliage, and the abundance and brightness of the fruit during 
the winter months, make this one of the most desirable of the Amer- 
ican Hawthorns as a garden plant. Several large plants of the Wash- 
ington Thorn can be seen on the slopes of the overlook near the top 
of Bussey Hill. 
The Silky Cornel, Cornus Amomum, is now opening its small white 
flowers. This has been much used in the Arhoretum borders, but in 
cultivation it is not a satisfactory plant unless it can be given sufficient 
room for its wide-spreading branches to extend freely and spread 
over the ground. When crowded by other plants the branches become 
erect and it loses its real beauty and value. To be seen at its best it 
should have a clear space with a diameter of not less than twenty feet 
in which to spread. It is well suited for the front of groups of larger 
plants; and there is no better shrub to plant by the margins of streams 
and ponds where its long branches can hang gracefully over the water. 
Its purple stems are attractive in winter, and the bright blue fruits 
which ripen in the autumn add to the attractions of this native shrub. 
In the Cornel Group, at the junction of the Meadow and Bussey Hill 
Roads, there is a good specimen of this plant and near it are two 
southern species which will not be in flower for a few days, C. asperi- 
folia and C. stricta. 
Attention is called to one of the new Honeysuckles from western 
China, Lonicera Henryi. This is a plant with long slender stems 
which, on its native mountains spreads over low bushes and rocks; it 
has large, dark green pointed leaves, and axillary clusters of flowers 
which when they first open are rose color but soon turn orange red; 
they have no perfume. There is a mass of this plant in full flower 
in the bed of Chinese plants on the southern slopes of Bussey Hill. 
The white-flowered Chinese and Japanese tree Lilacs ( Syringa pekin- 
ensis and S. japonica), many species and varieties of Philadelphus, the 
native Roses, the fragrant Rhododendron arborescens, and the yellow- 
flowered Woad-wax ( Genista tinctoria) are now conspicuous in the 
Arboretum. The last is the plant which covers many hills in Essex 
County, Massachusetts, where, an escape from cultivation, it has 
proved a dangerous weed and destroyed much of the value of thou- 
sands of acres of land. 
The Arboretum will be grateful for any publicity 
given these Bulletins.
