164 WILSON EXPEDITION TO CHINA 
Von Seemen in his sect. Subviminales names first S. Pierotii Miquel and adds 8. 
gracilistyla (or S. Thunbergiana Blume). According to my opinion S. Pierotii 1s 
much more closely related to the species of sect. Purpureae 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.
