Rosa Hugonis. Few plants sent from China to our northern gardens 
equal this Rose in grace and beauty. The long arching branchlets are 
so equally covered with flowers from end to end that the petals touch 
and make a continuous band of pale yellow. Individual flowers are 
about two and a half inches in diameter and have a delicate perfume. 
The leaves are small and pale green. Perhaps no other single-flowered 
rose is so beautiful, although the Cherokee Rose {R. laevigata) another 
Chinese Rose naturalized in the southern states, has handsomer foliage 
and larger flowers, but the flowers of the Cherokee Rose are white and 
not produced in such profusion. Rosa Hugonis has become popular in 
this country in a surprisingly short time and can now be found in quan- 
tity in many nurseries. 
Rosa omeiensis is also in flower. It is a vigorous shrub with stems 
covered with prickles and pure white fragrant flowers hardly more than 
an inch in diameter, borne at the ends of short lateral spikes, and 
bright red ellipsoidal fruit on stout, elongated, yellow, fleshy stalks and 
very showy. This Rose is common on the mountains of western China 
at altitudes of six thousand to eleven thousand feet above the sea, and 
sometimes grows twenty feet tall and forms great thickets. The name 
is derived from that of one of the sacred mountains of China, Mt. 
Omei, where it is common. The largest plant in the Arboretum is in 
the collectioh of Chinese shrubs on the southern slope of Bussey Hill 
with other Roses raised from seed collected by Wilson in western China. 
Horsechestnuts and Buckeyes. This is a good time to visit the col- 
lection of these trees which are grouped on the right hand side of the 
Meadow Road. The collection is nearly a complete one and contains 
all the American species and hybrids but the red-flowered Aesculus 
Pavia from the southeastern states and the Californian species which 
are not hardy, the two Chinese species and the species from the Him- 
alayas. The original Horsechestnut, Aesculus Hippocastanum, is the 
handsomest of the whole genus and one of the most beautiful trees in 
the world. It was brought to America at least one hundred years ago 
and there are many noble specimens in cities and towns of the eastern 
states. The Himalayan Horsechestnut and the species of central China 
are not hardy here, and the Arboretum has not succeeded in obtaining 
seeds of the north China species, Aesculus chinensis, which will prob- 
ably flourish in this latitude. 
A new Crabapple. One of the most beautiful when in flower of all 
the trees which have ever bloomed in the Arboretum is now flowering 
in the Peter’s Hill Group where several species of the American Malus 
are found. It is a double or semi-double form of the American Malus 
coronaria which was found a few years ago in the woods near Wau- 
kegan, Illinois, and was named the Charlotte Apple in honor of the 
wife of the discoverer. The Arboretum plant is still very small but 
would have been larger if it had not been broken down by boys two 
years ago. The flowers are fragrant, about two inches in diameter, 
with two rows of pale pink petals and far handsomer than those of 
the now well known Bechtel Crab, the double-flowered variety of 
another American species now in full bloom.
