perfection are often of a deep rich vinous red color. The other Amer- 
ican White Oaks which are hardy here, the Bur Oak (Q. macrocarpa), 
the Swamp White Oak (Q. bicolor), the southern Overcup Oak (Q. lyr- 
ata), the Post Oak (Q. minor) and the three Chestnut Oaks (Q. mon- 
tana, Q. Muehlenbergii and Q. prinoides) turn yellow in part or en- 
tirely in the autumn, and from most of these the leaves fall earlier 
than those of Q. alba. Among the White Oaks the leaves of which 
turn yellow in the autumn a single individual of the Swamp White Oak 
with large, bright scarlet autumn leaves is a remarkable exception to 
the general autumn color scheme of these trees. This is one of the 
most remarkable and interesting trees in the Arboretum collection of 
Oaks. It is growing in the mixed plantation by the road at the sum- 
mit of Peter’s Hill and was probably raised in the Arboretum, although 
unfortunately no record of its origin has been kept. 
Among the smaller trees with scarlet or crimson autumn foliage none 
is more beautiful now than the so-called Flowering Dogwood {Cornus 
Horida) which is unusually brilliant this year in its shades of crimson, 
scarlet and green. Its autumn beauty is increased by the contrast of 
of the color on the upper and lower surface of the leaves for only the 
upper surface changes color, the lower surface retaining the pale some 
times nearly white color of the summer. Another tree with leaves red 
or scarlet on the upper surface and pale on the lower surface, Acer 
nikkoense, is well worth the attention of persons interested in the 
autumn color of tree leaves. Acer nikkoense is a native of the moun- 
tain forests of central Japan and is one of the species with compound 
leaves related to the Ash-leaved Maple or Box Elder {Acer Negundo) of 
the United States. There are several good specimens of this handsome 
tree in the mixed plantation on the road near the top of Peter’s Hill 
where the leaves of these trees are now beginning to change color. 
Another small Maple from northern Japan, A. Sieboldianum, has been 
conspicuous this year in the intense scarlet of its leaves which are now 
beginning to fall. The best plants in the Arboretum of this tree are 
also in the mixed plantation on Peter’s Hill. 
Several plants are interesting now from the dark purple color of 
their autumn leaves. Among these is a variety of Prunus serrulata 
(var. pubescens), a large pink-flowered Cherry raised from seeds col- 
lected by Wilson in western China. One of the Japanese species of 
Stuartia (S. pseudocamellia) has autumn leaves even darker than those 
of this Cherry. This Stuartia is a hardy little tree with pale smooth 
bark exfoliating in large thin scales and white flowers which look like 
those of a single-flowered Camellia, and open in summer. There are good 
specimens of this tree on the left-hand side of Azalea Path. Akebia 
quinata, the Japanese species with leaves composed of five leaflets and 
small dark purple flowers, is well known in American gardens. The 
leaves fall late in the autumn without having changed color. The 
other Japanese species, A. lohata, is less well known in this country. 
From the other species it differs chiefly in the three, not five, rather 
larger leaflets which turn late in the autumn to a handsome dark bronze 
color. In this country the Akebias rarely produce fruit, which re- 
sembles in shape a short thick banana and is pale violet in color. It
