An exceedingly common species throughout central and western China, grow- 

 ing in thickets and margins of woods. The leaves vary considerably in size. The 

 young shoots, more especially the nodes, and the flower-buds are viscid. The 

 flowers vary in color from nearly white to dark red-purple. Maximowicz (Act. 

 Hort. Petrop. XI. 7) was disposed to regard the Chinese plant as distinct from the 

 Japanese. With the large series of specimens before us we can find no characters 

 on which to separate them. The color of the flowers is variable even in the Japa- 

 nese plant, and although the type has white flowers a specimen before us from 

 Nanokawa, Tosa, Japan, has obviously pale red-purple flowers.
