Honan: (ex Hers, 1. c). 



I am unable to separate from P. humilis, which agrees in the shape and 

 in the conspicuous reticulation of the leaves, Koehne's P. glandulosa var. 

 Purdomii of which I have before me besides Purdom's flowering specimen, 

 specimens with flowers and leaves from a cultivated plant determined by 

 Koehne himself as var. Purdomii. 



From Shantung and from Honan I have seen no specimens and it is 

 possible that these references belong to P. glandulosa to which I refer 

 the only specimen of this group I have seen from Shantung. 



1 Walpers changed Bunge's name to P. Bungei on account of Cerasus humilis Mori- 

 son of 1827, but the combination under Prunus was not made until 1834 by Colla, one 

 year after the publication of Prunus humilis Bunge.
