ARBORETUM NOTES. 59 
MAGNOLIACEAS. 
There are two trees (of slightly different va- Macnola 
rieties), against the arboretum wall; both flourish- 
ing; flowered well this spring (1871). They seem 
not to suffer from the most severe winter frosts, 
but the flower buds are very lable to be killed 
by the late frosts 1n spring. 
MAGNOLIA PURPUREA. 
Loudon, v. 1, 282. 
Several good plants of this in the arboretum and eer 
American Garden. It seems quite hardy here, 
and flowers well, but, though some of the plants 
(I believe), are as much as 35 years old, none of 
them have grown to more than about eight feet in 
height. 
Loudon’s description of this Magnolia is very 
good. 
I observe in the two Chinese species— 
Magnolia purpurea and Magnolia conspicua—that 
the flower buds are readily distinguishable from 
the leaf buds, both by size and shape, quite early 
in the season, long before any of them have begun 
to expand. This is not so apparent in the 
American Magnolias. 
The proper season for its flowering is May, but 
sometimes it flowers again, partially, in July or 
August.
