A Evonymus known as E. Hamiltonianus, var. semipersistens, a 
shrub of uncertain origin but probably Chinese, is valuable because the 
leaves are still as green as they were early in the season. The flowers 
of this plant, like those of all the species of Evonymus, are small, and 
the fruit is unusually small, inconspicuous and late ripening; and it is 
only for the green of its leaves in late autumn that this plant is val- 
uable. A good specimen can be seen in the Evonymous Group on the 
right-hand side of the Meadow Road. All the forms of the common 
Lilac ( Syringa vulgaris) are still as green as they were at midsummer, 
and the leaves of Magnolia glauca are still nearly as bright and shining 
as they were two months ago. 
The mild winter and the abundant rains of the early spring, and of 
October have been favorable to conifers, and many of the trees in the 
Pinetum have never looked better than they do today. This, of course, 
is not a good climate for conifers and some of the most beautiful and 
interesting of these trees cannot be grown here at all, including nearly 
all the species from western North America and those from the south- 
ern United States and Mexico. The coniferous trees of the countries 
of the Mediterranean Basin, and of South America, Tasmania and New 
Zealand, too, are not hardy here. Those of northeastern North America 
and the Rocky Mountains are the species on which we can best depend, 
and among these the White Pine, the Red Pine, the Canadian and 
the Carolinia Hemlocks, the Red Cedar, the Arborvitae, the Colorado 
White Fir ( Abies concolor), the Colorado Douglas Fir ( Pseudotsuga 
Douglasii) can be counted among the most beautiful conifers in the 
world. All the species of central and northern Europe are hardy here 
but are often short-lived. So far as it is possible to judge by an experi- 
ence only of from twenty to thirty years all the Siberian and north of 
China conifers are promising here, as are nearly all the Japanese spe- 
cies, although some of these are more valuable ornamental trees here 
than others. Of the great number of new conifers recently raised here 
from seed collected in western China, the most important probably of 
all the Arboretum introductions it is still too soon to speak, but, judging 
by the climate where these trees grow, it is not improbable that some 
of these Firs and Spruces may succeed in New England. 
These bulletins will now be discontinued until the spring. 
An illustrated guide to the Arboretum containing a map showing the 
position of the different groups of plants has recently been published. It 
will be found useful to persons unfamiliar with the position of the differ- 
ent groups of plants. Copies of this guide can be obtained at the Admin- 
istration Building in the Arboretum, from the Secretary of the Massa- 
chusetts Horticultural Society, 300 Massachusetts Avenue, Boston, from 
The Houghton, Mifflin Company, 4 Park Street, Boston, at the Old Cor- 
ner Bookstore, Bromfield Street, Boston, and at the office of the Harvard 
Alumni Bulletin, 50 State Street, Boston. Price, 30 cents. 
The Arboretum will be grateful for any publicity 
given these Bulletins.
