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.
Range & Status
Native; an annual, Mediterranean-Atlantic species, extending north to the Channel Islands (Jersey) and Cornwall.
Principally a coastal plant of the southern half of The Lizard (SW61 and SW71), where it has been recorded in just 23 1km squares, but only five since 1999.
Habitat & Ecology
Maritime and sub-maritime, it grows both on the serpentine and schists, on cliff slopes and edges. It may be found further inland around rocky outcrops, in pockets where the soil is shallow and the vegetation short and more open. A southerly aspect is favoured and plants tend to occur singly.
Habitat destruction would seem to be its only threat.
Some degree of grazing is beneficial as this helps to maintain a dwarf, open herb-rich turf. Much of the southern part of The Lizard is SSSI and managed by the National Trust and Natural England.
