tive plants with the Viburnums of North America. To these much of 
the late spring and early summer beauty of the Arboretum shrubber- 
ies is due, and the successful cultivation here of these plants is at last 
making their value known and appreciated. Thirty years ago it was 
practically impossible to buy an American Viburnum in any nursery, 
but now several of the species are largely propagated in many North 
American nurseries and have been used in considerable quantities in 
many American parks. 
About a dozen of the American Viburnums are thoroughly established 
in the Arboretum, the different species flowering through period a of 
two months. The earliest to flower and the most difficult to establish 
here satisfactorily, V. alnifolium, often called V. lantanoides, the Hob- 
ble Bush or Moosewood of northern woods, has been out of flower for 
several weeks and now the only species in flower is the Black Haw, 
V. prunifolium. This is a small shapely tree of the Middle States 
where it is often extremely common. The flowers are in convex clus- 
ters and are followed by sweet blue-black fruits. These and the leaves, 
which late in the season turn deep wine color, make this a particu- 
larly attractive plant in the autumn. Several other species will be in 
flower in a few days and will be mentioned in later issues of these 
bulletins. 
Three species of Enkianthus, an Asiatic genus of the Heath Family, 
are unusually full of flowers and flower-buds this year. The largest 
of the Japanese species, E. campanulatus, is now in flower and the 
flowers of the other species will open in a few days. E. campanulatus 
is a tall shrub with bell-shaped flowers hanging gracefully in long 
clusters which are partly hidden by the leaves. There are two forms 
in the collection, one with pale yellow flowers striped with red, and 
the other with rather smaller red flowers. The leaves of all these plants 
turn brilliant scarlet in the autumn and for its autumn colors E. cam- 
panulatus is much cultivated in Japanese gardens. The three species 
are in the Shrub Collection, and there is a large group of them on the 
lower side of Azalea Path where E. campanulatus can now be seen in 
its greatest spring beauty. 
Of Chinese plants flowering here for the first time attention is called 
to Lonicera Koehneana , a large hardy and vigorous shrub with dark 
red-purple branchlets, thick yellow-green leaves with conspicuous veins 
and pale yellow flowers slightly tinged with red on the outer surface 
of the corolla, and to Neillia sinensis , an interesting plant related to 
the Spiraeas. The former is in the bed of Chinese shrubs on the south- 
ern slope of Bussey Hill, in which a number of the new Cotoneasters 
are also in flower, and the Neillia is on Hickory Path near Centre 
Street. 
The Arboretum will be grateful for any publicity 
given these Bulletins.
