Prunus Maximowiczii belongs to the Mahaleb section of 
the cherries, but is distinguished from the other cultivated 
species of that group by the conspicuous foliaceous bracts 
on theinflorescence. Jt is closely allied to P. szechuanieca, 
Batalin, a species probably not in cultivation, which 
differs by its subumbellate inflorescence, its much shorter 
peduncle but longer pedicels and by its conspicuously 
glandular bracts very villous beneath. Originally 
discovered in Eastern Manchuria and described by 
Ruprecht in 1857, P. Mazximowiczu has since been found 
in Japan, Sachalin and Corea. It did not reach this 
country until 1895 when it was sent to Kew by Prof. 
Sargent from the Arnold Arboretum, to which establish- 
December, 1915.
