RANUNCULACEAE. — CLEMATIS 337 



1600-2300 m., June and August, 1907 (No. 1233=^); Ichang, A. Henry 

 (No. 1556). 



The broader and larger, more pubescent leaflets usually truncate or subcordate 

 at the base, less deeply incised, with obtuse and broader teeth generally distin- 

 guish this variety from the type. The specimens before us strongly suggest that 

 they belong to C. grata Wallich, but we have referred them to C. apiifolia D. C., 

 chiefly on account of their 3-foliolate leaves. The Vitnlba group is extremely 

 puzzling and none of the species have clearly defined limits. 



No. 1233^* has the under surface of the leaves densely clothed with soft, gray 

 villose pubescence.

The typical form as represented by Wallich's figure quoted above, apparently 

 does not occur in China.

Western Hupeh: vicinity of Ichang, A. Henry (No. 4330, type); 

 Patung Hsien, thickets and stony places, alt. 1000-1600 m., August 

 and December 1907 (No. 665) ; Ichang and immediate neighbourhood, 

 A.Henry (No. 2721). Szech'uan: without locahty, A. Henry (No. 

 7230). Formosa: 1864, Richard Oldham; South Cape, A. Henry 

 (Nos. 904, 904'*). 



This is a fairly common low-level plant ip western Hupeh being usually found 

 in stony places by the side of streams or roads fully exposed to the sun. It differs 

 from Wallich's figure in its more acuminate, often trifid or sometimes 3-foliolate 

 leaflets, with fewer, much coarser teeth. From C. grata, var. grandidentata Rehder 

 & Wilson it is readily distinguished by its smaller, often trifid or 3-foliolate, more 

 acuminate leaflets, usually 5-6 cm. long and 3-5 cm. broad and generally cordate 

 at the base, by the more numerous flowered cymes and small, green, leaf-like 

 bracts. It is also a more hairy and much less ornamental plant.
