H2, around 1875; it has not been found since. The plants are more like A .trichomanes with stouter rachides and thicker leaf tissue, the upper pinnae being confluent. (See A.G.H.Alston, Proc.Linn.Soc.Lond., 152: 139; 1940 and J.D.Lovis in C.A.Stace (ed.), Hybridisation and the Flora of the British Isles: 105; 1975). 3 3 4 9 4 5 Ni 7 5 HX HW ASPLENIACEAE 21.5 x 1 Asplenium X microdon (T.Moore) Lovis & Vida (A .billotii x scolopendrium; x Asplenophyllitis microdon (T.Moore) Alston) This hybrid, intermediate between parents, is likely to be confused only with A. x jacksonii: the latter has a triangular frond-shape instead of a tapered one as in A. x microdon.

A southern sub-Atlantic species widespread throughout Britain and Ireland. A rock plant with some base (possibly calcium and/or magnesium) requirement, tolerating medium exposure; it is frequently found in man-made habitats (e.g. mortared walls) in lowland Britain. This is a species which can tolerate considerable shade and it will remain as a terrestrial plant in climax woodland established over calcium-bearing rock scree. 4 6 0 6 51 5 4 3 2 1 0
