The specimens collected by Sir J. D. Hooker have been 80 
well examined that little more can be made out of them, nor can 
all the characters given be satisfactorily verified. Though 
included in the flora, the plant does not occur in British India, 
but was collected on the Tibetan side of the Himalayas at an 
elevation of 5350 metres. This is interesting as being the 
highest altitude at which a species of Arenaria had been found 
until last year, though Mr. C. B. Clarke had collected specimens 
of A. densissima at 5100 metres. 
Hab. Tibetan Himalayas, in the Sikkim region.
