Purn Hill (

notified in 1990. The site is a small promontory of Carboniferous Limestone projecting southward from the main Mendip
ridge.

The SSSI citation sheet describes the site as having an "exceptionally diverse unimproved calcareous grassland flora". The richest grassland communities are situated on the thin and stony soils of the steeper west-facing flanks of the hill. Over 200 species occur in the sward, including Salad Burnet (

umbellifer species Honewort (Trinia glauca). White Rock-rose (Helianthemum apenninum) is found at the site and hybridises with Common Rock-rose (Helianthemum nummularium) to form the hybrid H. x sulphureum.[1] Forty species of grass occur at the site, including Somerset Hair-grass (Koeleria vallesiana) which in Britain is confined to the western Mendips. Musk Stork's-bill (Erodium moschatum) occurs here.[2]

The Mendip Way crosses the site.
