never been successfully grown in the United States or Europe is due to 
the fact that Japanese gardeners do not use a suitable stock for them. 
Some seventy-five named varieties of these Cherries with double or 
otherwise abnormal flowers, cultivated in Japan, are now in the Arbor- 
etum where they are being propagated. Among them are fifteen named 
varieties of the Sargent Cherry, and among these are some of the most 
beautiful of all flowering trees hardy in this climate and evidently des- 
tined, although still little known, to become important features in 
American gardens. Two of the handsomest of these double-flowered 
varieties of the Sargent Cherry are the forms alho-rosea and Fugenzo; 
the former has large rose-colored flowers changing to white as they 
open, and the other rose-pink flowers; this is well known in English 
gardens under the name of James H. Veitch. These two Cherries differ 
from the other Japanese double-flowered forms in the presence of two 
leafly carpels in the centre of the flowers. 
European and North American Cherries bloom a few days later than 
those from eastern Asia, and can be seen near them on the right-hand 
side of the Forest Hills Road from that entrance to beyond its junction 
with the Meadow Road. 
Shad Bushes. The Arboretum will be gay with the white flowers of 
these plants soon after this Bulletin reaches its Boston readers. Shad 
Bushes have been largely used in the plantations along many of the 
drives, and the general collection of all species is in the border between 
the Meadow Road and the parallel walk on the left-hand side entering 
from the Jamaica Plain gateway. Two of the species are native plants 
in the Arboretum, Amelanchier laevis and A. oblongifolia. The first 
is a tree of considerable size, and an inhabitant of rich upland woods 
and dry banks. A. oblongifolia is a large shrub rather than a tree, 
although tree-like specimens sometimes occur. It is easily distinguished 
from A. laevis by the silver color of the young leaves which at this 
season of the year are thickly covered with silky hairs. The earliest 
of all these plants to flower, A. canadensis, is a tree sometimes grow- 
ing to a height of fifty feet and from A. laevis easily distinguished 
by the covering of pale hairs on the lower surface of the leaves. This 
handsome tree is distributed from western New York to Louisiana and 
is the common Amelanchier of the southern states. 
An illustrated guide to the Arboretum containing a map showing the 
position of the different groups of plants has been published. It will be 
found useful to persons unfamiliar with the Arboretum. Copies of this 
guide can be obtained at the Administration Building in the Arbor- 
etum, from the Secretary of the Massachusetts Horticultural Society, 
300 Massachusetts Avenue, Boston, from The Houghton, Mifflin Com- 
pany, 4 Park Street, Boston, and at the office of the Harvard Alumni 
Bulletin, 18 Plympton Street, Cambridge. Price, 30 cents.
