*1: Lizard Downs, 1961,
JAP (BBSUK) (Paton 1969a: 708). [An earlier
record (Clodgy Moor, W. of Mousehole, in Curnow 1884) is not
supported by specimen: Paton 1969a: 708].
*2: Halgavor Moor, S.
of Bodmin, 1879, RVT (B) (Paton 1969a:
708).
Forms dense lawns and low rounded hummocks (height
5 cm or less). Characteristic of damp acid soils or peaty
slopes with very low, closely grazed vegetation. Occurs only
in fully insolated sites, on wet heathland (including heaths
over serpentinite on Lizard pen.), at edges of mires and in
grassland at base of slopes adjoining mires and acidic
flushes. It disappears when heathland vegetation is left
ungrazed or unburnt, since the resulting tall growth shades
its low hummocks. Associates recorded were Agrostis curtisii, Calluna vulgaris, low
Carex spp., Erica tetralix, Juncus effusus, Molinia caerulea and
Ulex
gallii.
