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