Arboretum, and one of the trees produced a few of its green olive-like 
fruits this year. In Japan this Torreya is a magnificent tree sometimes 
ninety feet high with a massive trunk and a dense crown of dark green 
shining leaves. It should be better known in this climate where it is 
apparently one of the rarest of exotic trees. The best specimen, 
probably, in the United States is in the Hunnewell Pinetum at Wel- 
lesley in this state. The peculiarity of this tree is that it does not 
begin to grow until July. In spite, however, of its short growing sea- 
son it makes long annual shoots and increases rapidly in height. There 
is a group of this tree among the Laurels at the base of Hemlock Hill; 
there is a plant of Torreya californica among the exotic conifers near 
the top of Hemlock Hill where it has been kept alive for several years 
by careful winter protection. As an ornamental tree it has no value 
in this climate. 
Chinese Cotoneasters. Several of the Chinese Cotoneasters in the 
collection of Chinese plants on the southern slope of Bussey Hill will 
be objects of much beauty for several weeks, for many of them retain 
their fruit until winter and their leaves are only now beginning to 
take on their brilliant autumn colors. The most beautiful of them 
perhaps now is the red-fruited Cotoneaster Dielsiana. C. divaracata, 
another red-fruited species, will be more beautiful in ten days’ time 
when the leaves will be bright scarlet. C. horizontalis and its variety 
perpusilla with their dark green leaves and small bright red fruits, 
will not lose their autumn beauty much before Christmas. These two 
plants with their prostrate stems spreading into broad, compact mats 
are well suited for the rock garden or to train against low walls. 
Hawthorns. Many of the American Hawthorns have now dropped 
their leaves. Two conspicuous exceptions are Crataegus nitida and C. 
cordata. The leaves of these two trees are turning red and set off to 
advantage their small, bright red fruits. There are large specimens 
of the former in the old Crataegus Collection on the bank between the 
Shrub Collection and the Parkway, and C. cordata can be seen on the 
Overlook and on Hickory Path near Centre Street. If a selection of 
twelve of the handsomest American Hawthorns for New England gar- 
dens were to be made these two should be among them. 
Pyrus ovoidea. In a few days the leaves of this Chinese Pear-tree 
will turn bright scarlet. The late autumn coloring of the leaves of 
this tree is not surpassed by that of any other plant in the Arboretum, 
and it is well worth a place in any garden for this alone. It is inter- 
esting, too, because the leaves of no other Pear-tree turn to brilliant 
colors, and because the yellow juicy fruit, unlike that of other pears, 
is smaller at the apex than at the base. There is a good specimen of 
this tree in the Pear Collection on the left hand side of Forest Hills 
Road near the Forest Hills entrance. 
Stewartia pseudocamellia. This is a small Japanese tree with erect 
growing branches, which produces in summer small, pure white, cup- 
shaped flowers and at this season of the year is interesting and attrac- 
tive on account of the dark bronze purple color of the ripening leaves. 
There is a specimen in the Shrub Collection and another on Azalea Path. 
The Bulletins of 1915 will be discontinued with this issue.
