ENUMERATION OF THE CHINESE AND KOREAN SPECIES. 



Sect. L NEMEXIA. A. De C. 



The section Nemexia has been used by De CandoUe 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 Nemexia and Eusmilax because of the variable number of ovules. 

 De Candolle recognized the apparent relationship of S. ferox Walhch 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.
