The Japanese Cherry here figured is most nearly related 
to PP. serrulata, Lindl., from which it may be readily 
distinguished by its few-flowered, sessile or subsessile 
umbels and its broader and more coarsely serrated leaves, 
the teeth of which are hardly pointed. P. serrulata has 
long been in cultivation in European collections under the 
name P. Pseudo-cerasus, and has been figured at t. 8012 
of this work under that name. This error we have been 
enabled to detect and remedy through the kindness of 
Protessor Seward, who has permitted us to study the types of 
Lindley’s two species which are preserved in the University 
herbarium at Cambridge. P. Sargentii, the subject of our 
late, was first raised in the Arnold Arboretum from seeds 
collected in Japan in 1890 by Dr. Bigelow, and was again 
introduced to the same collection in 1892 by Professor 
Sargent who, in 1893, preseuted seeds to Kew. Sargent
