This is the plant collected by Mr. George Forrest on dry- 

 rocky pastureland in the Yang-pi Valley, western slopes 

 of the Tali range, during his first exploration of Yunnan, 

 under the field number 4101, and assigned by him 2 to 

 P. Listeri, King. Upon his herbarium sheet Mr. Forrest 

 went further and named at first his plant P. obconica, 

 Hance, var. glabrescens, Franch. (see p. 312). In this 

 particular identification I believe that Mr. Forrest was 

 right for a portion of his specimens. That he did not 

 maintain Franchet's varietal name in his published account 

 of his Yunnan primulas was due in part, I think, to the 

 example of Pax (see p. 312), in part to the fact that he 

 associated specimens, collected under the field number 

 1815, "on moist moss-covered ledges of cliffs, open or shady 

 situations, in the side valleys on the eastern flank of the
