164 WILSON EXPEDITION TO CHINA 



those of Cotoneasier bullata and the fruits are jet black. Franchet does not give the 

 color of the fruits in his original description of Cotoneaster moupinensis, but from 

 fragments we have, kindly communicated from Paris, they appear to us as if they 

 would be black when mature. Since the leaves and flowers of this black-fruited 

 variety agree exactly with Franchet's original description, and, since this is the 

 common plant of the region Franchet's type came from, we have referred hia 

 name to this plant and accepted Bois' name of bullata for the red-fruited form, 

 which differs besides in the smaller flowers and decidedly more wrinkled leaves; 

 it is, too, a comparatively rare plant, though scattered over a wide area in western 

 Szech'uan. 



Our specimens exhibit considerable variation both in foliage and in size of the 

 corymb. No. 857, from Mupin, has rugose leaves, but this character varies con- 

 siderably even on the same shoots.
