 Appleyard's Feather-moss "Brachythecium appleyardiae" was described as new to science from this site in 1981, although doubt has been cast on the validity of the species as a result of genetic evidence published in 2005 which suggests that this moss is in fact a member of the widespread moss species "Scleropodium cespitans".Grassy clearings within the combe are the only site in Avon where the nationally scarce Spreading Bellflower "Campanula patula" is found.The species was first found here in 1829.
