Status in Britain: Nationally Scarce
Additional: Biodiversity Key Species; Near endemic - outside British Isles known only from N.Spain.

This is an oceanic species, confined to the West and North of Britain. It occurs on acid rocks in a number of well-drained, humid situations in North Wales, including N-facing crags, crevices of shaded block scree, and in the spray zone of waterfalls.

In common with other species of Campylopus it has long, narrow leaves tapering to fine points, and a very thick nerve occupying most of the leaf width. The upper quarter of the leaf has spiny teeth at its margin, and the plant is mid- to dark green in colour.
