ASPLENIUM. Spleenworts and Wall-rue. [Aspleniaceae]

Eight species of Asplenium are native to Britain - Black Spleenwort agg. (A. adiantum-nigrum), Sea Spleenwort (A. marinum), Lanceolate Spleenwort (A. obovatum), Irish Spleenwort (A. onopteris), Wall-rue (A. ruta-muraria), Forked Spleenwort (A. septentrionale), Maidenhair Spleenwort (A. trichomanes) and Green Spleenwort (A. viride). A ninth species Smooth rock-spleenwort (A. fontanum) is introduced. Only one dipterous miner, the agromyzid Chromatomyia scolopendri, is recorded on Asplenium in Britain, and this also occurs on Phyllitis and Polypodium. See POLYPODIUM. Elsewhere the fern-feeding agromyzid Chromatomyia scolopendri and the fern-feeding anthomyiids Chirosia grossicauda and Chirosia histricina are recorded mining Asplenium. Two non-dipterous miners are recorded on Asplenium in Britain.
