RANUNCULACEAE. — CLEMATIS 333 



This variable species is abundant on the mountains of central and western 

 China. Of the specimens we have referred to the typical form that from Szech'uan 

 has small and often entire leaflets. The varieties ruhens Wilson and Wilsonii 

 Sprague show a greater divergence from the type than any of the Himalayan 

 specimens we have seen.

Western Hup eh: north and south of Ichang, thickets, alt. 1300- 

 2300 m., May and October 1907 (No. 587, in part; climber 2-4 m., 

 flowers rose-pink); Changyang Hsien, alt. 1300-1600 m., June 1907 

 (No. 587, in part; flowers rose-pink); Hsing-shan Hsien, thickets, alt. 

 1300-2300 m.. May 25, 1907 (No. 587, in part; cHmber 2-4 m., flowers 

 rose-pink) ; Fang Hsien, thickets and rocky places, alt. 2000-2600 m., 

 May 27, 1907 (No. 2465; climber 2-3 m., flowers white with rose- 

 pink reverse); without locality, May and June 1900 (Veitch Exped. 

 Nos. 633, 889); without locahty, A. Henry (Nos. 5437, 5437^). 

 Western Szech'uan: west of Kuan Hsien, Niu-tou-shan, thickets, 

 alt. 2600-3000 m., June 20, 1908 (No. 2463; climber 4 m., flowers 

 white with rose-pink reverse); Chiu-ting-shan, alt. 1600 m., May 22, 

 1908 (No. 2466; climber 4 m., flowers rose-pink). 



The foliage of this variety is very dark coloured and readily distinguishes the 

 plant when out of flower. As Sprague (Bot. Mag. sub t. 8365) has pointed out, 

 there is considerable doubt as to this Chinese plant being the same as the Indian 

 plant to which Kuntze applied his name rubens, basing it upon a statement of 

 Hooker & Thomson. By the Chinese in Hupeh this plant is called Ta-huai-t'ung.
