SAPINDALES. 
THE SAPINDUS, ^SCULUS AND RHUS ALLIANCE. 
This is a large alliance of trees, shrubs, climbers, 
and more rarely herbs, largely tropical, but 
well represented in temperate regions. Several 
of our finest flowering and foliage trees and 
shrubs are included within it. I shall mention but few 
of the tropical species. There are 24 tribes, 195 
genera, and 1550 species in the alliance and many of 
them are beautiful greenhouse and sub-tropical 
garden plants. 
Sapindus, “soap berry” has 10 species in the 
tropics and sub-tropics of Asia and America. We 
have one species, S. marginatus, found from Kan- 
sas through the South, and in Mexico. In the 
latter country it is a large tree, but in Georgia, 
etc , it is smaller, with pinnate leaves, racemes of 
whitish flowers, and globose yellow fruit. The 
genus is the foundation of the alliance. 
Kolreuteria has 2 species, both Chinese. K. 
paniculata is well-known in gardens, it is an ele- 
gant small tree with yellowish flowers, which ap- 
pear towards the end of summer, K. bipinnata, 
with brighter flowers, is less common. 
Stocksia has i spe- 
cies, a native of Belu- 
chistan. 
Xanthoceras has 
but j[ species, a beau- 
tiful flowering small 
tree or shrub intro- 
duced to American 
gardens about 1873. 
It does not appear to 
succeed very well at 
Washington where I 
first saw it. At Phil- 
adelphia it is a shrub. 
At Wilburtha, New 
Jersey, there is the 
largest and tallest 
plant known to me 
in the country. It 
measured ii ft. 5 in. 
in height in 1895. It 
is the property of W. 
P. Perry, Esq., and 
was obtained by him 
from Washington, It 
flowers beautifully, 
but does not perfect 
seeds. Further north 
on Long Island there 
are six feet plants 
which perfect good crops nearly every year. 
yEsciilus has 14 species of trees and shrubs from 
North America, North India, Persia, and China. 
The American kinds are trees and shrubs, the trees 
with dull red, pink, or yellow flowers, and the 
shrubs (often called Pavia) with white, pink, or 
dark red flowers. It is a little strange that these 
pink flowered dwarfs are so seldom seen in 
gardens. The Asiatic Horse chestnut is a 
finer tree and more familiar than the American 
ones. It varies a good deal, even in the ordi- 
nary type, and there are double flowered forms 
both in white and red. The beautiful little tree 
known as XL., rubicunda in several varieties, differ- 
ing in the intensity of their color, has been 
referred in name at least to AL. glabra, an 
American form, and to AL. hippo-castanum an 
Asiatic form. It seems strange that a full series of 
specimens should fail to determine this variety. I 
suppose there is no doubt about the double red form 
of the Asiatic species? The finest specimens I have 
seen considered as to height alone, were examples 
of 2E. rubicunda then known as R. carnea, in the 
old Capitol grounds at Washington — since im- 
proved.
