not otherwise different from the common form and flowers with it in 
the rear of the Horsechestnut Group. Near this is another form of 
this tree (var. leucodermis ) from southern Missouri and Arkansas, with 
pale bark which blooms about two weeks later than the type and is 
just coming into flower. 
The other yellow-flowered arborescent Horsechestnut of the eastern 
states ( A . octandra) differs from the Ohio Buckeye in the absence of 
prickles from the fruit. It is a larger tree, growing sometimes on the 
slopes of the southern Appalachian Mountains to the height of eighty 
feet, and blooms a week or ten days later. This is a valuable orna- 
mental tree which is now rarely found in collections. The other arbor- 
escent species of the southern states, the red-flowered A. Pavia , is not 
yet established in the Arboretum, although some garden forms of this 
tree (var. atrosanguinea and var. Whittleyi), flower here freely. 
From a race of hybrids between A. octandra and A. Pavia some 
valuable garden plants have been obtained. This hybrid appeared in 
Paris at the beginning of the last century and the correct name for it 
is A. hybrida, although in recent European publications it is sometimes 
called A. versicolor. The flowers are of different shades of red, and 
individuals differ in foliage, in the size and color of the flowers, and in 
their time of opening. There are two large bushy specimens of this 
hybrid quite different from each other in appearance in front of the 
Horsechestnut Group and next to A. glabra on the Meadow Road, and 
other forms can be found in the rear of this group. Of recently de- 
scribed species from the southeastern states only A. georgiana from 
central Georgia will flower this year. This is a broad, round-topped 
shrub, growing sometimes to the height of five or six feet, with large 
red and yellow flowers in long compact clusters, and a plant of much 
promise as a garden ornament. A large bed of this shrub will be 
found on the path in the rear of the Horsechestnut Group and opposite 
the mass of A. parviflora. This well known shrub is the last of the 
Horsechestnuts to flower and its tall narrow spikes of white flowers 
will not open before midsummer. Near this bed are beds of young 
plants of the yellow-flowered A. arguta , a small shrub from eastern 
Texas, and of the beautiful red-flowered shrub or small tree from the 
southern and southwestern states usually called A. austrina. Much 
attention has been paid to the formation of the Arboretum collection 
of Horsechestnuts and it will well repay the attention of persons inter- 
ested in a beautiful genus of now too little known trees and shrubs 
well suited for the decoration of northern parks and gardens. 
Among the American Magnolias in the group on the right-hand side 
of the Jamaica Plain entrance M. Fraseri is already opening its large 
cream-colored flowers which are conspicuous on the ends of the 
branches. This small tree is a native of the southern Appalachian 
Mountains and is perfectly hardy in the Arboretum. The small, bright 
canary yellow flowers of M. cordata open almost at the same time. 
This Magnolia was sent from the United States to France more than 
a hundred years ago and is now only known in the descendants of the 
trees cultivated in France, all attempts to find the wild trees in recent 
years having proved unsuccessful. This is a shapely, desirable and 
perfectly hardy ornamental tree. The leaves are dark rich green; the 
abundant flowers are of an unusual color for those of a Magnolia, and 
the second crop of flowers which these trees usually produce in sum- 
mer adds to its value. The cultivated trees produce no seeds, and as
