tendency to the formation ofa fruit. The Wistaria ~ 
is certainly one of the most beautiful climbers 
that we have in cultivation. 
Mr. Bentham tells me (November, 1875), that

England, but he has specimens of the pods from 
China. He suggests that its barrenness in this 
country may be owing to the absence of some 
insect which may be necessary to its fertilization.

Two fine specimens, one in the arboretum, the 
other on the east side of the pleasure ground, 
both planted by my father in 1826; several 
smaller and younger ones in various parts of the 
erounds. The two largest plants both of them 
divide near the ground into several stems, which 
rise up like trees, but in oblique and crooked 
or tortuous directions, branching out into leafy 
heads at some height from the ground. In the 
gardens of France and Italy, where the Judas 
tree is now very much cultivated, I have generally 
seen it take more decidedly the form of a tree, 
with a single trunk, and (as Loudon says), a 
flat spreading head. On the other hand, where 
[ have seen it growing wild (as near Tivoli and
