Willow); often forming large patches or sometimes extensive
carpets. All six records from vc1 were associated with old
mining areas or drainage from metalliferous mine-spoil, in wet
heath, hollows with heathy vegetation, among Juncus effusus in
marshy area, on peaty soil of damp bank, on floor of young
birch woodland, alongside stream and beside a small spring.
Eight vc2 records were associated with old china-clay workings
or other excavations (including very old gravel pits): under
or close to edges or young growths of Grey Willow scrub at wet
heathland edges or among Molinia caerulea tussocks or
in mature Grey Willow carr. One vc2 record in shallow water of
hollow of old mine working near stream, well shaded inside
grove of deciduous trees. Two vc2 records on wet heaths in
areas formerly much disturbed by tin-streaming. Associates

var. commune, Sphagnum denticulatum,

Juncus effusus,
