The type of the Fulvum series, Rh. fuluum, Balf. f. et W. 
W. Sm. is a plant of the Shweli-Salween divide in latitudes from 
25° 20’ N. to 25° 30’ N. as we know of it up till now. This 
new species Rh. fulvoides we must look on as a geographical 
form of the Fulvum type from the Mekong-Salween divide 
having a wider range over areas between latitudes 28° 10’ N. 
and 28° 4o’ N. From the Kari Pass on the Mekong-Yangtze 
divide in lat. 27° 40’ N. Forrest has brought specimens in 
immature fruit which I do not separate from Rh. fulvoides, 
and on the mountains N.E. of Chungtien in lat. 28° N. close 
to the Eastern boundary of N.W. Yunnan Forrest found a 
plant of this phylum which seems to be also this Rh. fulvoides. 
These extensions of the distribution out of the Mekong-Salween 
divide find a parallel in species of other phyla of Rhododendron 
and also in other genera.
