which has proved to be one of the best additions to garden plants 
which has ever been made. The first plant obtained by this cross was 
called P. Lemoinei; it is a perfectly hardy shrub from four to six feet 
high and broad, with slender stems which bend under the weight of the 
countless flowers which are intermediate in size between those of the 
parents and retain the fragrance of those of P. microphyllus. There 
are at least a dozen distinct forms of this hybrid made by Lemoine, 
varying considerably in the size of the flowers and in the time of flow- 
ering. One of the handsomest of these plants, perhaps, is called 
Candelabre, which is a dwarf with flowers larger than those of either 
of its parents, an inch and a half wide, with petals notched on the 
margins and without the fragrance of its parents. Other distinct forms 
equally hardy and handsome are Avalanche, Boule d* Argent, Bouquet 
Blanc, Erectus, Fantasie, Gerbe de Neige and Mont Blanc. 
Neillia sinensis. This is the only member of a genus of the Rose 
Family related to Spiraea which has flowered in the Arboretum. It is 
a native of western China where it was collected by Wilson and intro- 
duced into cultivation through the Arboretum. It is a tall hardy shrub 
with gracefully spreading and drooping branches, light green, incisely 
cut, pointed leaves from an inch and a half to two inches long, and 
clear pink flowers about half an inch in length, in short terminal ra- 
cemes. It is one of the handsomest and most interesting of the hardy 
shrubs introduced by Wilson from western China. 
Rosa Marretii is blooming remarkably this year. It is a tall, broad 
shrub with arching stems, pale green leaves and large pink flowers. 
It is a native of northern Hokkaido and of Saghalin where it was dis- 
covered by the late Abbe Faurie who sent seeds to the Arboretum 
in 1908. This plant, which is still rare in cultivation, promises to be 
a good addition to the single-flowered Roses which can be successfully 
grown in this climate. One of the hardiest and best growing of the 
new Roses, Rosa bella, was raised at the Arboretum from seeds col- 
lected by Purdom in northern China, and is a plant which when better 
known will be popular. It is a large shrub with bright red flowers an 
inch and a half in diameter, and bright red fruit. It is with the other 
Chinese plants on Bussey Hill. 
Rosa multiflora cathayensis is again covered with its great clusters 
of pink flowers and expanding flower-buds. The Chinese representive 
of the white-flowered R. multijiora of Japan, it is one of the most 
beautiful Roses and interesting as the wild type from which the Chi- 
nese derived the now well known Crimson Rambler Rose and another 
old-fashioned garden Rose, the Seven Sisters Rose (R. multiflora pla- 
typhylla).
