stigma planum 5-lobatum. 
Species ex affinitate Rh. anthopogonoidis, Maxim. sed foliis 
minoribus ad 1.5 cm. longis, bracteis interioribus lepidotis et 
puberulis haud sericeis, calyce minore lepidoto, corolla rosea haud

Yunnan. Mountains of the Chungtien plateau. Alt. 13,000 
ft. Lat. 27° 30’ N. Matted shrub of 2 ft. Flowers pale rose. 
Ledges of cliffs and boulders. G. Forrest. No. 12,631. July 1914. 
A dwarf species this, belonging to a small series including 
Rh. anthopogonoides, Maxim., Rh. clivicolum, Balf. f. et W. W. 
Sm., Rh. fragrans, Maxim. and Rh. primulaeflorum, Franch. 
They resemble both the Cephalanthum series and the Antho- 
pogon series in many characters, but they have not the 
loose indumentum of Cephalanthum nor the rufescent agglu- 
tinate indumentum of Anthopogon. Rh. cremnophilum, 
is marked out from its fellows by the small elliptic or 
slightly oblong-elliptic leaves and its short twisted branches, 
and is in all its parts smaller than either Rh. antho- 
pogonoides and Rh. clivicolum. Then its flowers are rose 
coloured, as they are in Rh. fragrans. I may add that the 
cuticle on the epidermal cells is very thick, exceeding the 
lumen of the cells, and the epidermal papillae are conoid or 
even ovoid and set very close together.
