Yunnan: 10 miles to south-west of Mengtsze, alt. 1600 m., November 1899, 

 seeds collected in Veitch Expedition; specimens from Hort. Veitch, June 1911, 

 No. 1315, type; mountains north of Mengtze, A. Henry (No. 10785). 



A handsome species most closely allied to C. coriacea Franchet, which has obo- 

 vate, rounded more coriaceous leaves. In Henry's specimen the leaves are rather 

 smaller, more obtuse, and the calyx shows a tendency towards becoming glabrescent. 

 From C. pannosa Franchet, with which it has been confounded in cultivation, 

 its larger, more coriaceous, shining green leaves and larger corymbs readily dis- 

 tinguish it.
