The Snowberries ( Symphoricarpos ) generally retain 
their fruit late in the autumn, and on many of the plants 
the leaves are still green and fresh, increasing the beauty 
of the snowy white berries. There are several species 
and forms in the Shrub Collection but the handsomest is 
the common Snowberry of all old gardens, S. racemosus 
var. laevigatas, a plant now becoming naturalized in New 
'England. The type of the species is a much smaller 
plant with small fruits and therefore of less ornamental 
value. 
The so-called French Mulberry, Callicarpa Americana, 
with its axillary clusters of violet-colored fruits, is one 
of the handsome autumn shrubs of southern woodlands. 
Unfortunately it is not hardy here, and the only really 
satisfactory species of this genus which has yet been 
grown in the Arboretum is the Japanese Callicarpa 
The branches of many other trees and shrubs in die 
Arboretum are still covered with showy fruits and ma iy 
of them have great decorative value in addition to their 
value as garden plants. The branches 01 the common 
Barberry, Berberis vulgaris, with its drooping clusters of 
red fruits are very ornamental in the house, as are those 
of its allies, B. Canadensis, B. Amurensis, and B. Reget- 
iana. Berberis Canadensis, which is a native of the 
southern Appalachian Mountains and southern Missouri, 
is a smaller plant than the European Barberry with smal¬ 
ler leaves and fruit and is still rare in cultivation. It 
retains its leaves later in the season than most of the Bar¬ 
berries of this group. 
Showy fruits still cover the branches of several Haw¬ 
thorns ( Crataegus ), especially those of C. nitida, one of 
the most ornamental species of the entire genus, and of 
Peach Seedlings, ready {or budding. August 5, 1915, Washington Nursery Co., Toppenish, Wash. 
Japonica. This is a smaller ulant than the American 
species but the fruit, although smaller, is of the same 
color and is now conspicuous on the branches from which 
the leaves have mostly disappeared. There are a num¬ 
ber of plants of this small shrub on the left hand side of 
Azalea Path near its entrance from the Bussey Hill Road. 
The silvery white tails of the fruit of a Japanese 
Clematis (C. apiifolia ), now make a brilliant show on the 
right hand side of the Jamaica Plain entrance where this 
vine has rambled over a number of large shrubs; there 
is a plant, too, on the trellis at the east side of the Shrub 
Collection. It is one of the small flowered species, the 
white flowers appearing after those of the native C. Vir- 
giniana and before those of the Japanese C. paniculata. 
It is hardy, fast-growing and blooms freely every year, 
and as a decorative plant its value is increased by the late 
persistence of the fruit, which now forms one of the 
handsome objects in the Arboretum. 
C. aprica, a southern species which is perfectly hardy 
here. The best Hawthorn, however, for winter decora¬ 
tion is Crataegus cordata, the so-called Washington 
Thorn, a slender tree of the southern states which is still 
covered with its leaves now turning orange and scarlet 
and making a handsome contrast with the small bright 
red fruits which remain on the branches until spring 
without change of color. 
Among the Cornels or Dogwoods the latest to hold its 
fruits is Cornus racemosa, sometimes called C. paniculata 
and C. candidissima, a common and widely distributed 
native shrub. The leaves have now fallen but the 
bushes are completely covered with clusters of dull white 
berries borne on bright red stalks. This Dogwood has 
been largely used in the Arboretum shrubberies where it 
is now one of the most conspicuous and interesting 
objects.— Bulletin 35.
