usually 6 rays and in the longer teeth of the filaments. Deutzia Fargesii Franchet 
is easily distinguished by the broader less finely serrate leaves with the stellate 
hairs beneath having generally 6 to 7 rays and by the many-flowered inflorescence.

Most nearly related to D. coriacea Rehder, which is easily distinguished by its 
spinosely dentate leaves glabrous and smooth above and borne on longer petioles.
