China. The European and the American smoke-trees 
(Cotinus) are relatives of the sumacs; the former is some- 
times called the wig-tree, on account of the flower-clusters 
which become white and feathery in fruit; a dye is obtained 
from it which is called young fustic. 
Crossing the transverse path to the triangle, the holly 
family is on the nearest point, shown by the serrate holly 
and the crenate holly, both from Japan, and the American 
holly; the European holly is grown in the conservatories. 
The Virginia winter-berry, of the eastern United States, 
bears its bright red berries far into the winter. On the 
opposite corner of the triangle is the staff-tree family, 
illustrated by many forms of Euonymus; the European 
staff-tree, the burning-bush of the eastern United States, 
the winged spindle-tree of eastern Asia and Bunge’s 
spindle-tree of the Amur region are shown. Pachistima 
Myrsinites, from the northwestern United States, is also 
represented. Crossing the path to the north of the triangle 
we come to the maple family; most of the maples are trees, 
so they must be looked for in the arboretum, but here are 
specimens of the Ginnala maple, from northern China and 
Japan. Immediately beyond this is the bladder-nut 
family, represented by species of the bladder-nut (Sta- 
phylea), both from the New and the Old World. Fol- 
lowing the path to the west, we come to the buckeye family, 
represented here by the small-flowered buckeye, from the 
southeastern United States; many of the buckeyes and 
horse-chestnuts are trees, and are grown in the arboretum. 
Following this is the soapberry family, with the genus 
Xanthoceras, a native of China, as a representative. At 
some distance from the path to the left is the buckthorn 
family; the most familiar plant here is the New Jersey tea, 
or red root, of eastern North America; its leaves were 
formerly used as a substitute for tea; the jujube-tree, an in- 
habitant of the Mediterranean region and temperate Asia, 
is of this family, its edible fruit oval in shape and about 
the size of a plum, with an acid taste when fresh; the
