Western Szech'uan: Wa-ssu country, Wen-chuan Hsien, among 

 rocks, alt. 2300 m., July 1908 (No. 1866, young fruits only); eastern 

 Szech'uan, Tchen-keou, R. P. Farges (flowers). 



Lonicera trichogyne is closely allied to L. stenosiphon Franchet from Yunnan, 

 which differs in its smaller narrow, oblong, acute leaves, pubescent on both sides, 

 longer glabrous peduncles, larger distinctly toothed calyx and shorter stamens with 

 the anthers reaching only to the base of the limb. The description of the flowers 

 given above is taken from Farges' specimens, which differ from Wilson's No. 1866 

 in the leaves being only 12-18 mm. long.
