The distinctive characteristic of this species from Deutzia grandi- 

 tiota is the form of hairs on the lower surface of the leaves. In this 

 species they are bigger and only 4-8 radiated, while in D. grandiffora 

 often 10-12 radiated and covers fully the lower surface of the leaves 

 giving glaucous appearance to them. Even in var. glabrata the size 

 and form is different from those of D. primitolia. The length of the 

 petioles, peduncles and pedicells ai'e too variable individually.
