460 WILSON EXPEDITION TO CHINA 



Western Szech'uan: Chiu-ting-shan, cliffs, rare, alt. 2600 m., 

 June 22, 1908 (No. 3012); Mupin, woods, alt. 2000-2600 m., June 

 and October 1908 (No. 1128). 



This species I have named at the request of Mr. Wilson in compliment of Dr. 

 Esserteau, bacteriologist, at one time attached to the Medical School at Chengtu, 

 to whom Mr. Wilson is indebted for much kindly service during the years 1908 

 and 1910.

The species is named for the wife of the author. It differs from S. Esserteauiana 

 Koehne in its broader leaflets with the veins deeply impressed above and strongly 

 elevated beneath, and in their snowy white, not greenish white, under surface.
