It is singular that no good figure should exist of so beau- 
tiful and well known a tree as this, and one introduced before 
1758, which can only be accounted for by its being usually 
confounded with the P. baccata (Tab. nost. 6112), which was 
not introduced till 1784, and from which its connate styles and 
totally different fruit, crowned by the persistent calyx, at 
once distinguish it. I have seen no native specimens, and 
though stated by the earlier authors, including De Candolle, 
to be a native of Siberia, Ledebour does not seem to have 
known it, for he quotes De Candolle and Willdenow’s de- 
scription, giving Siberia with a query as its habitat; and, 
though described by Miller in 1760, is a native of Dahuria, 
whence it was introduced into the St. Petersburgh Gardens, it 
is not included in Turczaninov’s Flora Baical-Dahurica. 
Regel, however, gives Dahuria and the Baikal as its native 
countries ; and Karl Koch says North China, Tartary, and 
Southern Siberia. De Candolle, Ledebour, and Lowdon all 
describe the calyx as glabrous, but it is decidedly woolly,
