 shoot with extremely broad-based spines; in Herb. U. S. Dept. Agric); 

 "ad monasterium Altin" (ex Kanitz, 1. c). — See also Meyer, 1. c. 



Distribution: also Central Asia. 



It is remarkable that this Central Asiatic species should range as far 

 east as Shansi and Honan, but I am unable to find any character to dis- 

 tinguish the specimens cited above from those collected in Turkestan. 

 From the two other yellow-flowered species of northern China R. Ecae 

 is easily distinguished by the glandular dots on the under side of the leaflets 

 and their doubly serrate glandular margin.

 Chin. Ost.-Tib. 414 (1922). 



Shensi: Tsin ling shan, southeast slope of Tai pei shan (ex Pax & K. 



Hoffmann, 1. c). 



This species is said to be related to R. graciliflora Rehd. & Wils. and 

 seems to differ according to the description chiefly in its mostly 13-foliolate 

 leaves with reticulate leaflets and in the smaller white flowers.
