calcareous sand of slopes and flat areas with very short
vegetation in dune grassland. Single record of small amount at
Sennen Cove in similar habitat, in very short grassland on
steep hillslope above beach with cover of calcareous blown
sand. Scattered records from several other mostly basic
habitats: At Kynance in thin short grassland growing unshaded
on shallow soil layer over low outcrop of serpentinite on
heathland near sea. Small amount in short vegetation near
pathway on damp heath over gabbro (NW. edge of Crousa Downs).
Twice on old concrete of ruins of china-clay dries, almost
