Cornish Red Data (2009)

The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.

Linaria supina - Prostrate Toadflax

b> Range & Status

Possibly native (Stace, 1991); an annual that has been recorded in east & west Cornwall and south Devon, and in south-west Europe.

Regional Distribution

Very local and rare, often occurring as a casual, it has been noted in 24 1km. squares since the first record in 1848. It has undergone a dramatic decline and persists at only three railway sites.

Habitat & Ecology

Dry sandy or gravelly open ground, often by railway lines, growing with such plants as Silver Hair-grass Aira caryophyllea , Common Centaury Centaurium erythraea , Common Bird's-foot-trefoil Lotus corniculatus and Rat's-tail Fescue Vulpia myuros .


Very threatened by the loss of open habitat, tidying up of marginal habitats by weed-spraying, changes in land use and building development.
