Distribution Maps of Bryophytes in Britain

Abstract

Flask-shaped gemmae of British Leptodontium flexifolium (With.) Hampe are discussed in the context of previously described ellipsoidal and oboyoid gemmae and point to the need for taxonomic reappraisal of the two closely related species, L. flexifolium and L. styriacum (Jur.) Limpr.. Scabrous leaves in the former are associated with mamillae rather than papillae.
