Tahoma; \colortbl ;\red35\green31lue32;\red0\green0lue255; Range & Status
Native; A Submediterranean-Subatlantic species. Found in extreme south-west Wales, central-southern England, south-west Ireland, the Channel Islands and Cornwall, with very few sites elsewhere in southern England.
It is locally frequent on The Lizard (SW61 and SW71), and found more rarely on Goss Moor (SW96) and near Carrine Common (SW74). It has disappeared from most of its former sites except on The Lizard. It was once known from 93 1km squares.
Habitat & Ecology
Heathland, especially open habitats along damp winter-wet tracks and in short, damp turf, often associated with rock outcrops.
Loss of suitable habitat, often due to scrub encroachment, as well as by the re-surfacing of heathland tracks.
The management of suitable sites that maintain a regime of reduced competition from more vigorous plants is needed. Most of the remaining sites are protected.
