ENUMERATION OF THE CHINESE AND KOREAN SPECIES. 
Sect. I. NEMEXIA. A. DeC. 
The section Nemezia has been used by De Candolle and later writers as a de- 
pository for a large number of species that have no immediate relationship to the 
American members of the section. Smilax china Linnaeus and its relatives were 
placed in both Nemezia and Eusmilax because of the variable number of ovules. 
De Candolle recognized the apparent relationship of S. feroz Wallich to the S. 
china group and the absolute similarity between S. stans Maximowicz and S. 
vaginata Decaisne, but still placed them in different sections. Neither is it possible 
to allow S. lanceaefolia Roxburgh and its relatives to remain in this section, as the 
habit of the inflorescence in this genus is plainly a better indicator of relationship 
than the presence of one or two ovules, which is often a variable character even in 
the same ovary.
