is in flower. The flowers and foliage resemble those of the Chinese 
plant but the branches, like those of its Turkestan parent, are much 
more upright in growth. 
Morus acidosa. This is one of the most interesting and perhaps one 
of the most economically valuable of the plants introduced by Wilson. 
It is a perfectly hardy shrub which on the cliffs of western China 
sometimes grows to the height of twenty feet, although usually it is 
not more than six or eight feet high. The plants in the Arboretum 
are now four or five feet tall and from six to eight feet in diameter. 
The leaves are sometimes deeply lobed and sometimes entire. The 
flowers, although rather smaller, resemble in general appearance those 
of other Mulberries. The fruit, which is produced in great quantities, 
ripens in the Arboretum at the end of June. It is about half an inch 
long, black and lustrous and has a pleasant subacid flavor. It is sug- 
gested that this Mulberry may prove exceedingly valuable in supplying 
hens with food. Its dwarf habit makes it possible to plant it in small 
yards; plants raised from seeds begin to bear fruit in six or seven 
years, and the fruit which drops in a small area under the bushes 
would be easily found by the birds. Morus acidosa is a common and 
widely distributed plant in eastern Asia, being found from Japan and 
Korea to the extreme western borders of China, in Formosa and in 
India. Plants now in flower in the Arboretum can be seen at the end 
of the bed containing the collection of Chinese plants on the southern 
slope of Bussey Hill. This is one of the coldest and most exposed 
positions in the' Arboretum. Several of these Mulberries can also be 
seen in the Peter’s Hill Nursery. 
Rhododendron (Azalea) canescens. The flowers of this northern pink- 
flowered Azalea soon follow those of Rhododendron (Azalea) Vaseyi, 
the earliest of the American species to open its flowers. It is a com- 
mon shrub on the hillsides of central Massachusetts, and ranges far 
southward in the eastern states., R. canescens has been largely planted 
on both sides of Azalea Path, and the mass of these plants on the 
right-hand side of the Meadow Road is covered with opening flower- 
buds and will in a few days be one of the most attractive objects in 
the whole Arboretum. 
Rhododendron (Azalea) Schlippenbachii. This Azalea, raised from 
seeds brought from Korea by Mr. Jack, has flowered abundantly this 
year on the upper side of Azalea Path. It is one of the handsomest of 
the Asiatic Azaleas, and has large, obovate leaves and white flowers 
more or less tinged with rose which are three inches or three inches and 
a half across. It is a very common plant on the low grass-covered 
hills which rise above the Korean coast and in eastern Manchuria, 
but it is still little known in gardens. Mr. H. J. Veitch found it in 
1892 in a nursery garden in Tokyo and sent plants to England where, 
although a picture of it was published two years later in the Botani- 
cal Magazine, very little has been heard of it. This beautiful plant 
promises so well in this climate that it should be taken up by American 
or Dutch nurserymen that it may be possible to plant it in quantity.
