222 BALFOUR—NEW SPECIES OF RHODODENDRON. 
Yunnan. Mountains in the N.E. of the Yangtze bend. 
Alt. 11,000-12,000 ft. Lat.27°45’N. Shrub of 3-5 ft. Foliage 
aromatic. Flowers white tube yellow. On ledges of limestone 
cliffs and rocky slopes. G. Forrest. No. 10,585. July 1913. 
A species not far removed from Rh. anthopogonoides, Maxim. 
but with smaller leaves and larger flowers, while the calyx in the 
two species is very different. In Rh. clivicolum the lobes are 
green, foliaceous not translucent, with large lepidote scales on 
the back and apparently increasing much in size after flowering 
is over. In Rh. anthopogonoides the calyx lobes are mem- 
branous translucent and elepidote outside. Rh. cremnophilum, 
Balf. f. et W. W. Sm. is also an ally, being one of the Fragrans 
series, but its smaller elliptic leaves and rose-coloured flowers 
separate it
