Silaum silaus (Pepper-saxifrage)
S. silaus is found in damp, unimproved neutral grassland, usually on clay soils. Its habitats include hay- and water-meadows, species-rich pastures and roadsides; it is occasionally found on chalk downs, railway banks and vegetated shingle. Lowland.
The 1962 Atlas indicated little change in the distribution of S. silaus before 1930. Since the 1962 Atlas there is evidence of a small but distinct decline throughout its range, e.g. in Somerset (Green et al., 1997) and Oxfordshire (Killick et al., 1998).
Eurosiberian Temperate element.
