The specimen from Mupin is glabrous, and the leaves glaucescent beneath and 

 so approaches the var. Fortunei. The specimen from Wen-ch'uan Hsien is only 

 slightly pubescent on the veins, while all the other specimens are more densely 

 pubescent beneath, but green, not glaucescent as described by Franchet. 



Here may be added a new variety from Yunnan collected by A. Henry: 



Spiraea japonica, var. stellaris Rehder, n. var. 



A typo recedit foliis dense et argute duplicato-serratis subtus ad venas pilosis 

 4-5 cm. longis, folliculis stellatim erecto-patentibus minoribus 2 mm. longis.
