A. spicata, A. pumila, A. ftorida and A. Bartramiana (bet¬ 
ter known as A. oligocarpa). The last is the most nor¬ 
thern of the eastern species and is a small shrub of cold 
swamps and bogs. Unlike the other species, the flowers 
are usually solitary or in few-flowered clusters. In cul¬ 
tivation it has been found to succeed better when it has 
been grafted on one of the strongly growing species than 
it does on its own roots. Practically unknown in culti¬ 
vation, all these species are delightful garden plants, and 
the study of the collection in the Arboretum at this time 
will be found valuable to any one interested in dwarf, 
hardy, early flowering shrubs. 
grant I lowers which are produced in rather small com¬ 
pact clusters and open from bright pink buds. As the 
I lowers in a cluster do not all open at the same time the 
mixture of white flowers and pink buds adds greatly to 
the attractiveness of the inflorescence. It is a rather 
dwarf shrub ol compact habit \\ ith pale green leaves and 
has not yet produced fruit in the Arboretum. There is a 
Japanese species, V. bitchuense, which somewhat re¬ 
sembles V. Carlesii, but the flowers are smaller and the 
habit of the plant is not so good. Mistaken by Japanese 
botanists for V. Carlesii, ibis plant has been propagated 
in Japanese nurseries and sent to the United States and 
Europe as V. Carlesii. In buying that plant care should 
be taken to secure the right species.

Early Flowering Viburnums 
The two Viburnums which flower here first are among 
the most beautiful of all the plants in this genus which 
can be grown in New England. One is American and the 
other is a native of Korea. The American species, V. alni- 
folium, the Moosewood of northern woods, is one of tin 1 
species on which the flower-clusters are surrounded by a 
ring of large pure white sterile flowers. It has broad, 
thick, heart-shaped leaves and showy fruit, and in the 
woods the straggling branches often take root and thus 
form thickets which make traveling difficult. This plant 
has never really succeeded well in the Arboretum and is 
difficult to cultivate, although good plants may occasion¬ 
ally be seen in other Massachusetts gardens. There is 
now a small plant in flower among the dwarf Birches on 
the Bussey Hill Road opposite the Viburnum Collection. 
The Korean species, V. Carlesii, is rightly considered one 
of the handsomest plants recently introduced into Amer¬ 
ican gardens. Its value is in the white, extremely lra- 
Prinsepia Sinensis 
This Chinese shrub, which has been grow ing in the 
Arboretum since 1903, has proved itself to be a first-rate 
garden plant for regions as cold as New England. It is 
a plant with long and gracefully ascending and spread¬ 
ing branches, the bright green leaves are almost the first 
to appear in the whole collection, and when they are 
more than half-grown from their axils tin 1 bright yellow 
flowers, which are about two-thirds ol an inch in 
diameter, appear in few-flowered clusters. The largest 
plant in the Arboretum is on Hickory Path near Centre 
Street, and there is a plant also in Iln> general Shrub Col¬ 
lection.
