Yunnan. Mountains of the Chungtien plateau. Lat. 27° 30’N. 
Alt. 13,000-14,000 ft. Matted shrub of 12-20 inches. Flowers 
deep rose purple, throat white. Open situations on cliffs and 
humus-covered boulders. G. Forrest. No. 12,614. July 1914. 
A bright floriferous species of the Lapponicum series. It is 
one of the plants which, like Rh. drumonium, Balf. f. et Ward 
and Rh. telmateium, Balf. f. et W. W. Sm., has punctulate under- 
leaf indumentum and also a lepidote corolla. Its floriferousness 
as seen on dried specimens is remarkable. A small shrublet 
with very thin erect twigs, it resembles in that both the species 
named, being likest Rh. telmateium in its hoary appearance but 
differing in its oblong or oblong elliptic not narrowly lanceolate 
leaves. Rh. drumonium is readily separated by its shorter style 
only about equalling not longer than the stamens.
