164 WILSON EXPEDITION TO CHINA 
those of Cotoneaster bullata and the fruits are jet black. Franchet does not give the 
color of the fruits in his original description of Cot t pi is, 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 his 
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.
