in eastern Asia which was raised here in 1893, and seems perfectly at 
home in the Arboretum where it has grown to be thirty feet high and 
forms a shapely pyramidal head densely clothed in dark green leaves which 
turn orange and red in the autumn; the white flowers are produced in 
many-flowered clusters and are followed by small red or red and yellow 
fruits. This is one of the most successful of the deciduous-leafed trees 
introduced into the Arboretum from Japan. There is a specimen close 
to the Wisteria trellis on the right hand side of the Forest Hills Road, 
and a larger one in the mixed plantation near the summit of Peter’s 
Hill. Handsomer is Sorbus Folgneri, one of Wilson’s introductions from 
western China which is now in flower in the collection of Chinese trees 
on the southern slope of Bussey Hill. It is a tree which Wilson saw 
in China sixty feet high with a trunk girth of twelve feet. The leaves, 
which taper to the ends, are green and lustrous above and covered 
below with white tomentum which is also found on the young branches. 
The flowers in lax clusters are white and from a quarter to o. half of an 
inch across, and are followed by egg-shaped, bright red fruit about half 
an inch long. In the Arboretum Sorbus Folgr^eri is now only about 
twelve feet high, with gracefully spreading and arching branches and 
a clean stem only a few inches in diameter. Although Sorbus Aria 
is not in the Arboretum, the interesting hybrid of that tree and the 
North American Aronia arbutifolia is established in the Shrub Collec- 
tion where it is named Sorburonia althia; it is also known as Sorbus 
alpina and is a plant of more interest to botanists than to gardeners. 
Beutzia liypoglauca. Many of the Deutzias recently introduced from 
western China give little promise of value in this climate, and some 
of the handsomest of these plants, like D. longifolia, D. Vilmorinae 
and D. discolor, are usually killed to the ground every year in the 
Arboretum. The specim.en, however, found by Purdom in northern 
China to which the name hypoglauca has been given has been growing 
and flowering here for several years and is a good addition to the short 
list of the entirely hardy species and hybrids of Deutzia which are suit- 
able for New England gardens. Another north China species D. 
graudiflora, is also hardy here. It is a dwarf shrub with larger flowers 
than those of other Deutzias. Unlike those of other species they are 
solitary or in two- or three-flowered clusters, and open as the leaves 
unfold and before the flowers of other Deutzias appear. More satis- 
factory, however, for New England gardens than any of the species 
of Deutzia are plants of the Lemoinei hybrids raised by Lemoine at 
Nancy by crossing D. gracilis and D. parviflora, another north China 
plant. The original hybrid is a vigorous shrub often four or five feet 
tall and broad. It never fails to cover itself every May with pure 
white flowers, and, like all the Lemoinei hybrid Deutzias, is easily in- 
creased by cuttings. There are several compact forms of this hybrid 
in the collection. Of these the most beautiful perhaps is called Boule 
e Neige. Not quite as hardy is Lemoine’s hybrid called D. rosea, ob- 
tained by crossing D. gracilis with the Chinese D. purpurea. There 
are several named varieties of this hybrid; they are small compact 
plants with white flowers more or less tinged with rose.
