“A species of the Lapponicum series. This the Yunnan 
form of the Szechwan Rh. flavidum, Franch. is readily distin- 
guishable from that species. The indumentum of the under side 
of the leaf has many more scales which are set much closer upon 
the greyish surface, and the scales are bicolour, about one-half 
dark brown, one-half pale green, equally intermixed ; the inflor- 
escence is larger and so are the flowers ; the corolla is copiously 
lepidote outside, not sparingly so or not at all as in Rh. favidum, 
and then there are only 5 stamens—apparently constantly. The 
style is shorter and is puberulous at the base. Rehder and Wilson 
describe Rh. flaviduwm, Franch. var. pstlostylum, which they 
separate from Rh. flavidum, Franch. by its duller green leaves, 
lepidote flowers, smaller calyx, glabrous style, smaller and more 
_ globose fruits. Ward’s plant is not this variety, two of the given 
characters of which seem not valid—the lepidote flower and the 
glabrous style—both of these I find in Franchet’s type.
