346 WILSON EXPEDITION TO CHINA 
Western Szech’uan: Wén-chuan Hsien, dry and rocky valleys, 
alt. 1300-2300 m., June and November 1908 (No. 1239, type; climber 
1.2-1.8 m., flowers purple; with flowers and ripe fruits). 
According to the description and figures given by Maximowicz in Bull. Acad. 
Sci. St. Pétersbourg, XXIII. 372 (1877), this species seems to be closely related to 
C. acutum Linnaeus, var. longifolium Ledebour, of which I have not been able to 
see good material. It also resembles the Chinese species of the sect. Endotropis, 
but these have a different corona, which in our species looks somewhat like that 
represented in Maximowicz's fig. 10.

Western Hupeh: Changyang Hsien, thickets, alt. 650-900 m., 
August 1907 (No. 2249; climber 3 m. tall, flowers white); Ichang, A. 
Henry (No. 2481); without precise locality, A. Henry (Nos. 2196,

(No. 1533; climber 1.8 m. tall, perianth green, corona waxy-white). 
In the plant from Kuling the flowers are a little smaller than in the other 
specimens.
