Tracheophyta MagnoliopsidaFabaceaeTrifoliumTrifolium scabrum


A winter-annual of thin, infertile, drought-prone soils over limestone, sand and gravel; by the sea also in summer-parched cliff-top grasslands. It grows in similar habitats to T. striatum, and frequently grows with it, but tends to occupy rockier, drier and more strongly leached (acidic) microsites. Inland, it is also found on road verges. Lowland.
