Yunnan: Tali range, G. Forrest (No. 4443, pro parte; ex Focke). 

 We have seen no specimens of this Rose, as Forrest's No. 4443 in the herbarium 

 of the Arnold Arboretum consists of branchlets of R. Banksiae, var. normalis only. 



To the section Synstylae probably belongs R. macrophylla, var. hypoleuca L^veille, 

 Fl. Kouy-Tchemi, 354 (nomen nudum) (1915), which according to the key has 

 exserted styles connate into a column, few-flowered corjTnbs and leaves glaucous 

 below.
