324 WILSON EXPEDITION TO CHINA 
Western Hupeh: Hsing-shan Hsien, thickets, alt. 1300-1600 m., 
June and October 1907 (No. 367; climber 2-2.5 m., flowers dark); 
Chienshi Hsien, thickets, alt. 1300-1600 m., June and October, 1900 
(Veitch Exped. No. 925, Seed No. 538); without locality, A. Henry 
(No. 6417). Eastern Szech'uan: Taning Hsien, thickets, alt. 
1600 m., June 1910 (No. 4564; climber 2-3 m., flowers chocolate and 
gold); Wushan Hsien, A. Henry (No. 5620). 
This species is common in western Hupeh and eastern Szech'uan in thickets 
on mountain slopes, but has not yet been reported from other parts of China. 
The leaves are extraordinarily variable in size and shape, but the nature and 
degree of pubescence are very constant and the species is a well-marked one. 
The capsule is conspicuously 6-costate, as Henry's No. 6417 clearly shows, and 
we suppose Hemsley's description of the capsule as “ inconspicue 6-costata " is a 
slip of the pen.

Western Szech'uan: Mupin, thickets, alt. 2000-2500 m., July 
1908 (No. 1982; climber 3-4 m., flowers brownish); Chiuting-shan, 
alt. 1600 m., May 22, 1908 (No. 1983; climber 2.5-3 m., flowers brown- 
ish); Wa-shan, thickets, alt. 2000-2600 m., July and October 1903 
(Veitch Exped. No. 4481; Seed No. 1423); same locality, A. E. Pratt 
(No. 3). 
This is à very common climber in thickets and on the margins of woods in 
extreme western Szech'uan. Wright suggests that this and A. Kaempferi Willde- 
now may be the same, but the flowers and fruit of the latter species are very 
much smaller and the two plants are dissimilar in appearance.
