I take the following two sheets to represent the same species ; 
the leaves are smaller and the flowers not well developed :— 
‘“* Shrub of 4-6 ft. Flowers pale yellow. In open situations 
on the margins of thickets in the mountains of the Chungtien 
plateau, S.E. of Chungtien, Yunnan. Lat. 27° 45’ N. Alt. 
to0,000 ft. July 1913.” G. Forrest. No. 10,527. 
“Shrub of 4-5 ft. Flowers dull green. In open scrub in 
the mountains in the N.E. of the Yangtze bend, Yunnan. Lat. 
27° 45’ N. Alt. 10,o00-11,000 ft. July 1913.” G. Forrest. 
No. 10,351. 
The calyx with lobes longer than the tube is rather remarkable 
for the genus. Closely allied are two other species from the 
same province. The calyx and fruit are much alike in all three, 
but there are considerable differences in the leaves and corolla. 
P. mekongensis, W. W. Sm. differs from P. yunnahensis in the 
more pilose leaves, deeper-cut calyx, and longer narrower corolla 
of a yellow colour. Its leaves are much affected by disease, and 
that may have had some influence on the hairiness. The third 
species, P. acutata, W. W. Sm., differs from the other two in the 
acuminate sharply-serrate leaves with a cuneate base and almost 
glabrous on both surfaces. Unfortunately flowers are lacking. 
The brief diagnosis above distinguishes it from P. yunnanensis,
