(Juglans cathayensis) is uninjured but some plants of J. regia raised 
here from nuts gathered by Wilson in western China have lost their 
buds, while others appear to be uninjured. Maples from western China, 
on the whole, are not promising. Acer griseum, A. fulvescens and A. 
pictum parvijiorum are still in good condition, but A. longifolia and A. 
Henryii, which have suifered before, are now killed; and A. Davidii, 
which once flourished in the Arboretum for several years, is again badly 
injured. The new Cherry-trees from western China are all in good con- 
dition with the exception of Prunus Conradinae. This tree has always 
been delicate in the Cherry Collection, and the large plants on Peter’s 
Hill have now all been killed. This handsome tree flowered two years 
ago on the grounds of the United States Agricultural Station at Chico, 
California. Neillia sinensis is uninjured and there appears no reason 
why this beautiful shrub should not become a popular ornament in 
northern gardens. The other Chinese species in the Arboretum, N. lon- 
giracemosa and N. ajffinis, have been killed to the ground but the roots 
are alive. The Chinese Spiraeas and Hydrangeas are uninjured, but 
some of the Deutzias like D. longifolia and the varieties of D. discolor 
have suffered as usual. Plants of all the Chinese Ash-trees are alive, 
although the winter has been too severe for a plant each of Fraxinus 
retusa var. Henryi and F. platypoda. Ligustrum Delavayanum has 
been killed to the ground, as has Daphne genkwa. The injury to this 
plant has been one of the serious results of the winter. The Chinese 
Buddleias are usually killed to the ground here; as they flower on the 
new shoots this is a matter of little importance, but the roots have 
now been killed. Styrax americana of the southern states has been 
killed and the Chinese S. dasyantha is so badly injured that it will not 
recover. Unfortunately the only species probably of this beautiful 
genus which can be successfully grown here are the Japanese S. japon- 
ioa and S. obassia, and in this region these do not always grow as 
well as they have in selected positions in the Arboretum. 
Forsythias. For the second time in three years many flower-buds 
have been killed on all the species and hybrids of this genus. On some 
plants, especially those in low positions, all the buds were injured but 
on high ground probably at least half the buds have opened. The hybrid 
F. intermedia and its varieties have suffered the most, and the Chinese 
F. suspensa and the Albanian F. europea have lost fewer buds than 
the others. 
All the Chinese Barberries with deciduous leaves are practically un- 
hurt with the exception of Berberis Wilsonae, which has always been 
rather tender here, its variety Stapfiana, which has always been con- 
sidered a hardier plant, and B. triacanthophora. Few Chinese Honey- 
suckles have suffered, but Lonicera pileata, which has flowered here 
for several years, is killed to the ground, and the beautiful climbing 
L. similis var. Delavayi has been killed. 
Hamamelis. All the winter-flowering Witch Hazel plants are unin- 
jured. Hamamelis vernalis was covered the middle of December with 
flower-buds which promised to open earlier than usual but the extreme
