Species Seriei Triflori. 
S.E. Tibet. Tsarong. Ka-gwr-pw. Alt. 12,000 ft. For- 
rest 14,535. July 1917. 
Very distinct of that phylum in the Triflorum Series which is 
next to Rh. rigidum, Franch. with close-set scales on the under- 
leaf surface. It may be put in the phylum of Rh. rigidum if-we 
extend that which is a distant-scaled type to forms like this. But 
then the flowers here are different notably they lose their bract- 
seales early. This plant hinges on to the forms leading to Rh. 
stereophyllum, Balf. f. et W. W. Sm. but there again the flowers 
are different. Note this also runs into the forms with impressed 
underleaf scales like Rh. cardioeides, Rh. depile and the like— 
and thence to Rh. oreotrephes and its phylum with its raised 
cales. In its phylum characters marking it are: small rigid 
leaves cordate: at base. rounded at top elepidote epilose_ above, 
densely lepidote below, the scales with curious resin-punctula- 
tion on the umbo, midrib below without scales. Calyx scale- 
fringed and corolla puberulous inside. 8 stamens—have not seen 
a flower with ro.
