 Shensi: Ki-fon-shan, near Pao-ki-scen, G. Giraldi 'ex Engler). 

 I have seen no specimens of this species from China, and it seems doubtful 

 whether the specimen from Shensi really belongs here. 



Deutzia corymbosa, var. yunnanensis Franchet in Jour, de Bot. X. 283 (1896), 



Yunnan (ex Franchet). 



This variety, incompletely described by Franchet without citation of specimens, 

 probably does not belong to D. corymbosa} it is possibly closely related to D. rubens 

 Render.

 of Harbin, August 31, 1903, C. S. Sargent. Korea: Fusan, May 1906, U. Faurie 

 (No. 361). 



Franchet's variety /3 mongolica does not seem sufficiently distinct to be separated 

 as a variety; of the specimens named above only Purdom's No. 40 with simple 

 hairs along the midrib beneath would belong to this variety; all the others must 

 be referred to his var. a Bungei, though I never saw a specimen with perfectly 

 glabrous leaves; they all have at least a few hairs, sometimes nearly imperceptible, 

 on the lower surface. 



Deutzia parviflora, var. musaei Lemoine in Jour. Hort. Soc. France, se"r. 4, 



III. 303 (1902). 



This variety, described from specimens cultivated at the Jardin des PI antes at 

 Paris, differs from the type chiefly in the larger more pointed leaves and denser 

 inflorescence with fewer creamy white flowers. 



30. Deutzia micrantha Engler in Bot. Jahrb. XXXVI. Beibl. No. LXXXII. 

 51 (1905). 



Shensi: Tsin-ling-shan, July 1900, G. Giraldi (No. 7179); In-kia-p'u, G. Giraldi 

 (No. 2526, ex Engler). 



Closely related to D. parviflora Bunge, from which it differs in the much smaller 

 flowers, in the shape of the inflorescence, and in the stellate hairs of the under 

 side of the leaves being more numerous and having generally 8-10 rays. 'The 

 inflorescence much resembles in its mode of branching that of D. mollis Duthie, 

 the partial inflorescence being rather dense and borne on elongated and remote 

 branchlets.
