4 WILSON EXPEDITION TO CHINA 



locality, alt. 1600-2000 m., October 1910 (No. 4182; 2-3 m., fruits 

 black); same locality, alt. 2000 m., October 1908 (No. 1051; 2-3 m., 

 fruits blue-black, seeds orange-red) ; same locality, alt. 2000 m., July 

 1908 (No. 3250; climber 2 m., flowers green); Wa-shan, thickets, alt. 

 1300-1600 m., June 1908 (No. 3251, in part; bush 1 m., flowers 

 greenish). 



Closely related to S. vaginata Decaisne from which it is easily distinguished by 

 its larger size and by the most peculiar papillate pubescence of the petiole and 

 leaf ribs. Some of the flowers on Wilson's No. 3242 are abnormal in possessing 

 both stamens and pistil.

Western Hupeh: Hsmg-shan Hsien, alt. 1000-1300 m.. May 8, 

 1907 (No. 3234; climber 3-5 m., flowers greenish yellow). Eastern 

 Szech'uan: Wushan Hsien, thickets, alt. 1300 m., October 1907 

 (No. 448; climber 2-4 m., fruit red). Chekiang : vicinity of Ningpo, 

 1908, D. Macgregor (six sheets). Korea: Quelpaert, "in sylvis Hal- 

 laisan," June and July 1909, Taquet (No. 3306, co-type of S. Taquetii 

 Leveill^); Hongno, May and August 1909, Taquet (Nos. 3307 and 

 3308). 



Although this species is credited by most writers as the source of " China root," 

 there is Uttle doubt that some of its relatives are also used for this purpose. The 

 Korean forms agree closely with the typical Japanese plants, having the same or- 

 bicular leaves and zigzag stems; the leaves of Wilson's No. 3234 from Hupeh also 

 resemble closely the Japanese type, while the leaves of his No. 448 are like those 

 of the Hongkong plant.
