able to expect that this Juniper may prove the most valuable plant 
which has yet been tried to hold the drifting sands of our eastern coast. 
Juniperus Sabina. The dwarfest of all the prostrate Junipers in the 
Arboretum collection is a form of this European species with branch- 
lets ascending only a few inches from prostrate stems and covered 
with dark blue-green scale-like leaves. The right name for this little 
plant is probably var. cupressifolia; another name is var. nana. A 
better known variety of Juniperus Sabina is the var. tamariscifolia 
from the mountains of central and southern Europe. This is a dwarf 
plant with procumbent or rarely ascending branches and needle-shaped, 
slightly incurved, dark green leaves marked on the upper surface with 
a white line. 
Autumn colors in the Arboretum have been at their best this week, 
although the leaves of many plants have already fallen and those of 
many others, especially of the trees and shrubs of eastern Asia, are 
still as green as they were at midsummer. Some of the most brilliant 
plants during the week have been individuals of the White Oak {Quer- 
cus alba), the leaves of other individuals being still entirely green; the 
Tupelo or Sour Gum (Nyssa sylvatica), of which there are a number 
of plants by the pond near the junction of the Meadow and Bussey 
Hill Roads; the American Smoke-tree {Cotinus americanus); the Fra- 
grant Sumach {Rhus canadensis or as it has been often called, R. aro- 
matica), which has been largely used as a border plant along the drives; 
many species of Crataegus on the eastern slope of Peter’s Hill; the 
curious Japanese Apple {Malus Tschonoskii); the Tulip-tree {Lirioden- 
dron Tulipifera) which is always splendid in its golden autumn dress; 
the Black Haw of the southern woods with its dark red leaves and 
fruit just turning from white to dark blue; the Sweet Gum {Liquid- 
ambar Styracijlua) , with its star-shaped leaves turning scarlet and 
yellow. In early spring the Arboretum owes much to the flo\vers of 
one of the native species of Juneberry {Amelanchier oblongifolia) which 
has been largely planted along the drives where there are now many 
large specimens. During the past week these plants have been as beau- 
tiful and conspicuous as they were in May, for the leaves have turned 
the color of old gold and have retained this color for several days. All 
the American species of Amelanchier are beautiful spring-flowering 
plants, and although they do not remain many days in flower no other 
shrubs can be more safely used to enliven wood and swamp borders in 
the northern states. The bright scarlet of the leaves of the Highbush 
Blueberry {Vaccinium corymbosum) is not now surpassed in brilliancy 
by that of any other plant in the Arboretum. Attention has often 
been called in these Bulletins to the value of this native shrub for gar- 
den decoration. Fortunately it was early planted in large numbers in 
the Arboretum shrubbery and many of the plants have now grown to 
a good size and show their value. As an ornamental plant this Blue- 
berry has everything to recommend it. The habit is excellent; it blooms 
freely and the flowers are handsome; they are followed by large dark 
blue fruits of the best quality, and if for no other reason it deserves 
a place in any garden for the late and splendid colors of its^ dying 
leaves. A number of plants at the entrance of Azalea Path opposite 
the Bussey Hill Overlook show the different shades of color the leaves 
assume at the end of October.
