Coombe, N. of Bude, Mar. 1963, JAP (BBSUK) (Warburg 1964:

Perhaps just an extreme form of P. cuspidatum with
leaves having consistently long hair-points, but unlike the
other forms of the species all of the older Cornish records
and both of the two recent records are from coastal
localities. The recent records are from free-draining
substrates in sunny S.-facing locations, as follows: W. of
Marazion: sandy soil on slope and top of Cornish 'hedge'
beside road, unshaded or lightly shaded by herbs. Black Head:
on small patches of compressed, partly bare soil on
little-used path on top of serpentinite sea-cliff, slightly
shaded by low Festuca (with Trichostomum
brachydontium, Weissia sp., Riccia
subbifurca).
Cfr: capsules immature 1, 2, dehiscing
2.
