not produced seeds and it has remained rarer in this country even than 
the other species. The large group of these plants on the right-hand 
side of Azalea Path shows the habit and autumn coloring of the leaves 
of the different species. 
Blueberries in autumn. The leaves of all the deciduous-leaved Blue- 
berries asd Huckleberries turn bright scarlet late in the autumn, and 
as a ground cover in native woods there are no more beautiful plants 
than the three dwarf Blueberries of the eastern states, Vaccimum 
pennsylvanicum, V. canadense, V. vacillans. In the whole northern 
hemisphere there is hardly a shrub which equals the Highbush Blue- 
berry, V. corymbosum, for the decoration of New England gardens. 
The white flowers in drooping clusters are beautiful, the blue-black 
fruits are even more beautiful than the flowers, but it is in the late 
autumn that this shrub is most valuable as a garden or woodside orna- 
ment for the crimson of its autumn leaves is not surpassed in intensity 
by that of any other shrub. There is considerable variety in the shades 
of color in the leaves of different individuals, and on some plants crim- 
son and green leaves are found together. There are a number of plants 
of this Blueberry on the sides of Azalea Path near its entrance from 
Bussey Hill Road which show the variety of autumn leaf color of this 
Blueberry. 
Forsylhias. The leaves of all the forsythias usually fall, like those 
of the garden Lilacs, without having greatly changed color, but occa- 
sional plants of F. suspenaa var. Fortunii occur on which the upper 
surface of the leaves turn bronze purple while the lower surface retains 
its summer color. Such plants are more valuable than those with green 
autumn leaves and should be propagated. 
Barberries in late October. The leaves of many of the Barberries 
in the Arboretum collection have now turned crimson, scarlet, or scarlet 
and orange, making these plants which are now covered with scarlet 
fruit conspicuous. Of the species closely related to the common Bar- 
berry {Berberis vulgaris) the handsomest perhaps is the Japanese Ber- 
beris Regelii, a large shrub with large pale flowers, large fruit and 
leaves which turn orange and scarlet. Although still rare here, this 
plant was brought to the United States more than fifty years ago and 
was long cultivated in the Parsons’ Nursery on Long Island as Berberis 
Hakkadate. The Chinese B. diaphana is probably now the handsomest 
of the species with dark crimson autumn foliage. This is a low, round- 
topped shrub broader than high, with large solitary flowers which rarely 
produces fruit here. The only objection to it is that the leaves unfold 
so late that the plants appear dead when other Barberries are covered 
with nearly fully grown leaves. Among the new Chinese species the 
most beautiful Barberry in the autumn is B. circumserrata, a small 
round-topped shrub with large solitary flowers and leaves which in an- 
other week will be of as brilliant shades of scarlet as those of any 
plant in the Arboretum. Other species which are particularly attractive 
this week are B. koreana, B. lucida, B. amurenais, and B. dictyophylla.
