164 WILSON EXPEDITION TO CHINA 



Von Seemen in his sect. Subviminales names first S. Pierotii Miquel and adds S. 

 gracilistyla (or S. Thunbergiana Blume). According to my opinion *S. Pierotii is 

 much more closely related to the species of sect. Purpureas than to S. gracilistyla 

 Miquel, which widely differs in its long thin styles, in the long narrow gland and in 

 the narrow acute bracts. A taxonomic arrangement of sections or even groups of 

 higher value with regard to the length of the style seems to me an artificial one.
