Cerastium glomeratum

Tracheophyta MagnoliopsidaCaryophyllaceaeCerastiumCerastium glomeratum


C. glomeratum grows in disturbed areas, often in places where there is some nutrient enrichment. It is fairly tolerant of trampling and is particularly common around farms, in gateways, on field edges, in bare patches in improved grassland, beside tracks and in waste places. It is also frequent on sand dunes and shingle. 0-610 m (Black`s Hope, Dumfriess.).
