twelve or eighteen inches high, first noticed on a hill near Rutland, 
Vermont, but now known to grow in many places in southern New 
England and to range into eastern Pennsylvania, and conspicuous in 
the autumn with its bright scarlet leaves and green, yellow or orange 
and red fruits. Two species of the group in the southern Appalachian 
Mountain region, C. Buckleyi and C. Boyntonii, are small trees and 
have grown in the Arboretum into dense pyramids now eight or ten feet 
tall, and still covered with dark green leaves which later turn to 
shades of orange and scarlet. 
The Tulip-tree (Liriodendron) is unfortunately not a native of eastern 
Massachusetts, although it occurs in the western part of the state and 
in Rhode Island. It is perfectly hardy here, and has grown to a large 
size in the neighborhood of Boston. It is therefore surprising that this 
tree is not more generally planted here for the American Liriodendron 
is one of the most magnificent trees of the northern hemisphere, grow- 
ing as it does when all the conditions of soil and climate favor it, as 
in the rich “coves” of the southern Appalachian Mountains, to the 
height of two hundred feet and forming a trunk eight or ten feet in 
diameter and free of branches for half its height. The tulip-shaped 
flowers and the leaves, which are of unusual shape, are beautiful and 
interesting, but attention is now called to this tree on account of the 
beautiful color of the autumn foliage. This when the leaves first lose 
their green color is bright clear yellow but later as they begin to fall 
becomes darker and the color of old gold. In October in those parts 
of the country like Delaware County in eastern Pennsylvania, and on 
the slopes of the southern mountains where the Tulip-tree forms a con- 
siderable part of the forest and often raises its head high above its 
humbler companions, its spire-like bright golden crowns produce a 
beauty which can be found in no other part of the world. The Chin- 
ese Tulip-tree of recent discovery has not proved hardy in the Arbor- 
etum. It is a much smaller tree than the American species with 
smaller flowers but larger and handsomer leaves. 
Pyrus Calleryana, This Pear-tree, which was raised here from seeds 
collected by Wilson in western China, has less beautiful flowers than 
many other Pear-trees, and the russet-colored fruit is not more than 
half an inch long. It may, however, prove to be one of the most val- 
uable plants introduced into the United States by the Arboretum, for 
it is now believed by American pomologists that it will prove to be a 
blight-resisting stock on which to graft the varieties of garden pears. 
The Arboretum trees appear to be the only ones in the United States 
large enough to flower and this year they have produced a good crop 
of fruit which will be sent to the Department of Agriculture for dis- 
tribution.
