*1: Lizard Downs, 1924,
WEN (BBSUK) (Paton 1969a:
On Lizard pen. it grows on acid soil over
serpentinite near rocks and on a little-used path, at unshaded
edge of heathland, plentiful in small area with slight
flushing. Also on thin soil, partly bare, over serpentinite
rock on exposed unshaded slope high on sea cliff (with Trichostomum
brachydontium), and among T. brachydontium on thin
unshaded soil over serpentinite rock in small old quarry above
sea-cliff. Malloch (1972) gives fuller ecological notes on the
species from the Lizard pen.
Several records from Isles of Scilly were on on
acidic unshaded substrates on open coastal heathland and cliff
tops; found growing on damp peat exposed in hollow in
heathland, on thin compressed stony soil by path on cliff top
and among other low plants on thin soil over edge of
near-horizontal granitic rocks (near Ophioglossum
lusitanicum) on heath.
