This plant, one of the lead of the genus Arenaria, is very common on walls, among rubbifh, and in dry and 
barren places. It flowers in June. . 
There is a neatnefs in it fufficient to recommend it as an ornamental plant for walls, rocks, &c. on which it will 
grow mod readily. 
The rigidity of its dalks, and thyme-like form of its leaves, readily didinguilh it from all its congener?.
