Effects of the Severe Winter. The condition of the new Chinese 
Roses in the Shrub Collection is not as bad as might have been ex- 
pected and will perhaps interest persons who are beginning to culti- 
vate these plants. The yellow-flowered species, Rosa Hugonis, the 
single and double-flowered forms of R. xanthina and R. Ecae from 
Chinese Turkestan are uninjured. The last has been considered rather 
a tender plant here. The least beautiful, perhaps, of yellow-flowered 
Roses it has considerable geographical interest. The following are also 
uninjured: R. davurica, R. sertata, R. Helenae, R. Sweginzowii, R. 
banksiopsis, R. saturata, R. setipoda, R. bella, R. omeiensis, and R. 
multiflora cathayensis. The stems of the following have been killed 
to the ground or nearly to the ground, but the roots are probably 
alive: R. oorymbulosa, R. Davidii, R. Prattii, R. filipes, R. Moyesii, 
R. Moyesii rosea, R. Gentiliana, and R. multibracteata. R. Willmottae, 
which grows well at Rochester, N. Y., but has always been tender in 
the Arboretum, appears to be dead. Additions to the number of Chin- 
ese Maples mentioned in the last Bulletin which have been killed are 
Acer sinense and A. tetramerum. The latter flowered in the Arbore- 
tum a year ago. Other Chinese plants which have been killed are 
Stachyurus chinensis, Sophora viciifolia, Viburnum ovatifolium, Sta- 
phylea holocarpa, Sorbus pallescens, Poliothyrsis sinensis, Fortunearia 
sinensis, Sycopsis sinensis, Liquidambar formosana monticola, and 
the Chinese form of Symplocos paniculata. The Sophora has been 
growing in the Arboretum since 1906, and as it has for several years 
flowered and produced great crops of seeds here it was believed to be 
one of the hardiest as it is one of the most beautiful shrubs of recent
