cies and has been much more generally planted. In commercial nur- 
series it is often sold under the name of Dimorpanthus mandschuricns. 
Japanese and Chinese varieties of this Aralia, although less hardy than 
its Siberian representative, can be seen in the group of these plants 
near the junction of the Meadow and Bussey Hill Roads. 
Rhus javanica, an eastern Asiatic Sumach which is perhaps better 
known as Rhus Osheckii or R. semialata, is a good August flowering 
tree in New England. In this country it is rarely twenty feet high, 
with spreading branches which form a broad round-topped head of hand- 
some, light green, pinnate leaves with a broad-winged petiole and rachis. 
The flowers are white in erect, long-branched, pyramidal clusters, ten 
or twelve inches long and standing well above the leaves. The fruit is 
globose, about a quarter of an inch in diameter, red, and in compact 
clusters. The leaves of few trees or shrubs turn in the autumn to a 
more brilliant scarlet. For its showy August infloresence and the splen- 
dor of its autumn foliage this Sumach should find a place in the plant- 
ing lists for northern gardens. 
Evodias are small summer-flowering Asiatic trees of the Rue family, 
widely distributed in eastern Asia and found also in Madagascar and 
Australia. The species have pinnate leaves, white or pinkish unisexual 
flowers in small clusters terminal on the shoots of the year, and dry 
capsular fruit. Like the Phellodendrons to which Evodia is related, 
they are protected from the attacks of insects by the pungent aromatic 
oil with which the leaves abound. • Evodia has been growing in the 
Arboretum since 1905 when Professor Jack brought the seeds of E. 
Daniellii from Korea. This handsome tree has flowered now for sev- 
eral years in the Arboretum. E. hupehemis, a common inhabitant of 
the forests of western Hupeh where Wilson found it growing to a larger 
size than the other Chinese species of this genus, is also established 
and flowers in the Arboretum. 
Stewartia pseudo-camellia, another summer-flowering tree, was 
among the first plants to reach the United States direct from Japan, 
and before 1870 was distributed from the Parsons Nursery at Flushing, 
Long Island. It produces its pure white, cup-shaped flowers, which 
resemble those of a single Camellia, in August; the autumn color of the 
leaves is dark bronze purple, distinct from that of any other plant in the 
Arboretum and handsome and interesting; the smooth pale gray bark 
which separates in large pale plates adds, too, to the interest of this 
tree. There are two specimens on the upper side of Azalea Path. 
A handsome dwarf Conifer. Among a large number of seedlings of 
the Carolina Hemlock {Tsuga caroliniana) raised at the Arboretum from 
seeds planted in 1881 two individuals are dwarf in habit. The smaller 
of these plants is now only ten feet high with a spread of branches 
of twelve feet, and the other is thirteen feet high with a spread of 
fifteen feet. They show no tendency to form a leader, and look as if 
they would continue to grow more rapidly in breadth than in height. In 
their wide-spreading and gracefully drooping branches they are more 
beautiful even than the well-known weeping form of Tsuga canadensis 
which has usually been considered the handsomest of dwarf conifers. 
These Bulletins will now be discontinued until the autumn.
