make a great show in early July. These and many of the other 
Bush Honeysuckles which can be seen in the Arboretum, where there 
is a large collection of these plants, are excellent shrubs for cold coun- 
tries like the extreme northern states and Canada. They are very 
hardy and grow rapidly; their flowers are abundant and handsome and 
no other shurbs have such brilliant fruit in early summer. These 
plants like rich well drained soil, and the fact can not be too often 
repeated that the large growing kinds like L. tatarica and most of its 
hybrids, L. Morrowii and L. Maackii, must have room in which to 
grow. A plot of ground twenty to twenty-five feet across is needed 
for one of these plants if it is to show all its beauty. There are a few 
good specimens of the large growing hybrids by the Bussey Hill Drive 
opposite the Lilacs where they have had room to grow, but it has been 
found necessary to move all the large growing Honeysuckles from the 
Shrub Collection and make a new planting of them on the slope between 
the Meadow, and the Bussey Hill Roads where most of them will have 
room enough to grow to a large size. This has been necessary because 
when these plants are crowded together or their branches are trimmed 
they are ugly objects and give no idea of their real beauty and value. 
The red fruit covered with hairs of Rhvs canadensis, often called R. 
aromatica, are also ripe. This is a shrub two or three feet high as 
it grows in the Arboretum with spreading and ascending branches, clus- 
ters of small yellow flowers which cover the naked branches in early 
spring, and leaves composed of three leaflets. The leaves of only a few 
plants turn here in the autumn to a more brilliant scarlet color. This 
Rhus has been largely used in the Arboretum for planting in front of 
taller shrubs along the borders of the roads. 
Stewartia pseudo-camellia is beginning to -flower this year two or 
three weeks earlier than usual. The pure white cup-shaped flowers of 
this small Japanese tree resemble those of a single-flowered Camellia. 
In the autumn the leaves turn dark bronze purple an autumn color not 
seen on the leaves of any other plant in the Arboretum. The smooth 
pale gray bark not unlike that of a Hornbeam adds to the interest of 
this tree. The flowers are, however, smaller than those of the two 
species of eastern North America, Stewartia pentagyna and S. Mala- 
chodendron, and less beautiful than those of the variety grandidora of 
the former in which the stamens are not yellow but purple. Two spec- 
imens of the Japanese tree have been growing for many years on the 
upper side of Azalea Path. 
Koelreuteria paniculata. This Chinese tree which will be in full 
bloom in a few days, is when in flower the most conspicuous of all the 
summer flowering trees which are hardy in this climate. It is a round- 
headed tree rarely more than thirty feet high, with large, compound, 
dark green leaves and great erect clusters of golden yellow flowers 
which are followed by large bladder-like pale fruits. This tree, which 
is hardy in Massachusetts, has been a good deal planted in this country, 
especially in the gardens of the Middle States. The Koelreuteria often 
appears in American nursery cataloges under the name of “Japanese 
Lacquer Tree,’' although it is not a native of Japan and has not lac- 
quer-producing sap.
