Mount Everest EXpEpDITION, 1921: Under boulders, 
17,500 ft., white; A. F. R. Wollaston, 197, September. 
Dr. Wollaston writes to me about this species.—It “‘ was the 
highest species found. It grows up to 18,000 ft. and above. 
The flowers are white but they fade into a poor kind of pale 
mauve. The plant is very scarce and was only found on the 
Kast (shaded) side of large boulders in the Kharta Valley. I got 
a small quantity of seed.” It belongs to a section of the genus 
that is purely Himalayan, the species grouping round the 
Nepalese P. rotundifolia of Wallich—not the Sikkim plant in 
cultivation under that name, which is P. cardiophylla, Ball. f. 
Other species of the series are P. cana, Balf. f., and P. Littledalei; 
Balf. f. The epidermal protective devices in this Mt. Everest 
species are very conspicuous. The plant is everywhere covered 
with remarkable long-stalked glands often tortuous and inter- 
locking, secreting white meal.
