OF THE GENUS ARENARIA. 411 
incrassato-induratus ; sepala lanceolata acuminata uninervia, late 
scarloso-marginata, apice recurva. Petala ovalia acuta ungui- 
culata, sepalis breviora. Glandule quadrate. Capsula ovoideo- 
globosa eoriacea, valvis 3 bidentatis dehiscens, apice attenuata 
obtusa. Semina pauca compressa pallida subauriformia. 
The quadrate glands at the base of 5 stamens determine the 
systematie position of the plant in the genus. Among Hima- 
layan species, it is nearest to A. oreophila, but it is readily 
distinguished from this, as from the other four species in this 
small group, by the petals being shorter than the sepals and by 
its habit. 
Hab. Kumaon: Kali Valley, on rocks near Byans, at 2800- 
3000 metres.
