Tracheophyta MagnoliopsidaUmbelliferaePimpinellaPimpinella saxifraga


A perennial herb of grassy habitats on well-drained soils, favouring those which are calcareous or otherwise base-rich, but also on acidic sands. It occurs on grazed and ungrazed chalk and limestone downs, in rough pasture and other grassland, in woodland edges and open rides; less frequently on roadsides and rough ground. Generally lowland, but reaching 810 m on Snowdon (Caerns.) and Dollywagon Pike (Westmorland).
