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: Hsing-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, T'aquet (No. 3306, co-type of S. Taquetii 
Léveillé); 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 little 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.
