fruit. The Arboretum plants flowered for the first time last spring 
and have not yet produced fruit. B. Gagnepainii is also a tall shrub, 
with yellow-gray branchlets, long slender spines and narrow spiny 
leaves. The small flowers are in from three- to eight-flowered clusters 
and are followed by pear-shaped, bluish black fruit one-third of an inch 
long. This Barberry has flowered and fruited in the Arboretum this 
year for the first time. B. verruculosa is a dwarf spreading plant 
sometimes three feet high and broad, with slender, semipendent branches 
covered with many long slender spiues and small, remotely spiny, 
toothed leaves dark green and very lustrous on the upper surface and 
silvery white below. The flowers are pale yellow and solitary or in pairs, 
and the fruit is about half an inch long and dark violet color or nearly 
black. This handsome little plant flowers irregularly through the sum- 
mer and early autumn and has not yet ripened its fruit in the Arbor- 
etum. These three Chinese evergreen Barberries are with the other 
Chinese plants on the southern slope of Bussey Hill where they have 
been growing for three or four years in an exposed position. 
Mahonias, as Barberries with pinnate leaves are now generally 
called, are not very hardy here with the exception of the Rocky Moun- 
tain M. repens which is a good plant in this climate and soon spreads 
by underground stems into broad clusters. The handsomer M. Aqui- 
folium, the Oregon Grape of the northwestern part of the country, 
lives in sheltered positions, but many of the leaves are usually injured 
by the cold. M. pinnata and M. japonica generally live here but 
cannot be recommended for general planting. They can be seen on 
Hickory Path near Centre Street. 
Viburnum rhytidophyllum. This plant attracted a good deal of at- 
tention when it was first raised from seeds collected by Wilson in 
China, but in eastern Massachusetts it is hardy only in sheltered posi- 
tions and usually suffers more or less every winter. In the neighbor- 
hood of Philadelphia, however, it appears to be perfectly hardy and 
specimens there are already fully ten feet high. It is a large shrub 
with stout erect branches and tomentose branchlets, and large dark brown 
leaves lustrous and deeply wrinkled on the upper surface, and covered 
below with a thick coat of gray or yellowish felt. The flowers are in 
compact terminal clusters which are formed in the autumn and are 
conspicuous during the winter, and the fruit is about a third of an 
inch long, at first bright red when fully grown and finally black and 
very lustrous. There is a plant of this Viburnum on Hickory Path 
near Centre Street, and another on the upper side of Azalea Path on 
which the flower-buds can now be seen. 
Kalmias. The most generally satisfactory broad-leaved evergreen 
which can be grown in this part of the country is the Mountain Laurel 
{Kalmia latifolia) which is one of the handsomest plants of the North 
American flora. There are forms of the Mountain Laurel with white, 
pink and red flowers and there are some monstrous forms which are 
more curious than beautiful. Two dwarf species, Kalmia angustifolia, 
the well-known Sheep Laurel of northern pastures, and K. Carolina 
from the southern mountains, although not often cultivated, deserve a
