BALFOUR—NEW SPECIES OF RHODODENDRON. 69 
Yunnan, Rh. Clementinae, Forrest et W. W. Sm., a large-leaved 
form with 7 corolla-lobes and 14 stamens. In the same year 
Kingdon Ward discovered Rh. aganniphum, Balf. f. et Ward, 
on Ka-gwr-pw and Doker-la in the Tsarong of S.E. Tibet. 
Now Forrest’s exploration of S.E. Tibet and the adjacent area 
of Western North-West Yunnan shows that the series is repre- 
sented by other Eber in that region, and Rh. flavorufum is 
one of them. On p. 131 will be found a description of Rh. 
schizopeplum, Balf. f. zt Forrest, from the Mekong-Salween 
ivide, a form with splitting indumentum but on different me 
from that of Rh. flavorufum. And there are others yet to 
described. The series is widespread apparently, but of all oe 
orms known no one exhibits features of indumentum so re- 
markable as those from which Rh. favorufum takes its name.
