large plants can be seen on Azalea. Path. Of Hex pedunculosa there 
are only small specimens in the Arboretum, where they can be seen 
on Hickory Path near Centre Street where they have been growing for 
several years. In Japan this is a small tree sometimes twenty or 
thirty feet tall, or more often a shrub. The leaves resemble in shape 
those of our Wild Cherry, and the handsome red fruit is borne on long^ 
stalks and is very ornamental. 
Andromedas. Andromeda, or as it is often called PieHs fioribunda, 
is one of the handsomest of the broad-leaved evergreen shrubs which 
are perfectly hardy in this climate. It is a round-topped shrub occasion- 
ally eight or ten feet across and four or five feet high, with small, 
pointed, dark green leaves, and short terminal clusters of white bell-shaped 
flowers. The flower-buds, which are fully grown in the autumn, are 
conspicuous and ornamental during the winter. This southern Appala- 
chian shrub is an old inhabitant of gardens and is still much propa- 
gated by nurserymen. The related Japanese species, Andromeda ja- 
ponica, is sometimes a small tree and has more lustrous leaves and 
larger flowers in larger clusters. The plant is hardy, but the flowers, 
which open early, are often injured by spring frosts. The so-called Bog 
Rosemarys, Andromeda polifolia and A. glaucophylla, although natur- 
ally swamp plants, can be grown in dry soil and are attractive small 
shrubs with small pale leaves and clustered white or pink flowers. 
Chamaedaphne calyculata. This, the so-called Leather Leaf, is an- 
other native small plant which can be successfully grown in dry ground. 
The small white flowers are in the axils of the upper leaves and are 
not very conspicuous, and as an ornamental plant the Leather Leaf is 
not as attractive as several of the smaller shrubs of the Heath Family. 
There is also a plant of the dwarf form in the Shrub Collection (var. 
minor). 
The Box Huckleberry. Among the easily grown and perfectly hardy 
evergreen plants of the Heath Family none is perhaps more beautiful 
than the Box Huckleberry (Gayiussocia brachycera) with its small, 
lustrous leaves which become the color of old Spanish leather in the 
autumn, small white' flowers and blue fruits. The prostrate stems 
spread into broad mats only a few inches high, and although the plant 
grows naturally in the shade of Oak woods it thrives in full sunshine. 
This is one of the rarest plants in North America and is now known 
to grow naturally in only one place in Pennsylvania. 
Blueberries, A few of the evergreen Vacciniums can be grown in 
this climate, including the Cowberry ( V. Vitis-Idaea) and its variety 
minus, low plants with tufted creeping stems, small pink or white 
flowers and dark red berries. The two Cranberries, Vaccinium Oxy- 
coccus and V. macrocarpon, although inhabitants of swamps, will also 
grow in dry ground and are beautiful plants. 
The only other broad-leaved evergreens which are perfectly hardy 
here are the Leucothoes, the Bear Berry, the Gaultherias, the Ledums, 
Leiophyllums, the Pachystimas, Evonymus radicans aud Vinca minor. 
The Bulletins for 1917 will now be discontinued.
