of the plants flowered but they are all in good condition. All the plants 
of the new Chinese genus of the Witch Hazel Family {Sinowilsonii) 
appeared to be uninjured in May but many of the branches died after 
the leaves were fully grown, and although these plants may recover 
their present condition is not satisfactory. 
Evergreen Barberries. It is a satisfaction to be able to report that 
the four species of evergreen Barberries from western China in the 
collection, Berberis Julianae, B. Sargentiana, B. Gagnepainii and B. 
verruculosa, are now in good condition, although the leaves of all but 
the last species were killed and many of those of B. verruculosa were 
injured. It may be expected therefore that these beautiful plants may 
continue to live in eastern Massachusetts if suitable positions can be 
found for them. 
Corylopsis. The two species of western China which were covered 
with flowers in the spring of 1917, C, Willmottiae and C. Veitchiana^ 
were killed to the ground by the cold of the winter and are now rep- 
resented by feeble stump-shoots, and it is doubtful if these plants can 
be sucessfully and permanently grown in this climate. The Japanese 
C. pauciflora and C. spicata, which lost their flower-buds and some 
branches have not looked well through the summer but are recovering. 
Another Japanese species, C. Gotoana, which was uninjured in bud and 
leaf, seems destined to become a popular garden plant in the northern 
states. 
Several other shrubs which were injured by the winter and in May 
and June gave little promise of recovery, are now alive and will prob- 
ably entirely recover. Among them is a plant of the Japanese Lindera 
obtusiloba which, although it has been growing in the Arboretum for 
twenty-five years, is still one of the rarest plants in the collection as 
it has not borne seeds and has proved difficult to propagate. This plant 
is most beautiful in the autumn when the leaves during the first week 
in November are the color of gold. Another Japanese Benzoin, B. 
sericea, which was injured by the winter will probably recover, although 
this plant has suffered in less severe winters and will probably never 
be valuable in this climate. The two Dipeltas, a Chinese genus related 
to Weigela, which were killed to the ground have produced shoots from 
the roots. These plants, although they have flowered sparingly in the 
Arboretum, have suffered from cold before and it is doubtful if they 
can be successfully grown in Massachusetts. Rhus Potaninii, Cornus 
paucinerviSy Salix Bockii, Osmaronia cerasiformis and Ceanothus 
Wrightii have recovered, as was predicted in the Bulletin issued on 
the 16th of May. The most important of these for the garden is Cor- 
nus paucinervis for it flowers here late in July when comparatively few 
shrubs are in bloom. It is a narrow shrub with numerous upright stems 
five or six feet high, small narrow pointed leaves with only two or 
three pairs of veins, small flat clusters of white flowers and small black 
shining fruits. If this plant proves as hardy in eastern Massachusetts 
as it has at Rochester, New York, it will be one of the most valuable 
of Wilson’s introductions from western China. Coluteas bloom on the 
branches of the year and all the species, although they had been killed
