Its difficult to know where to start but I’ve always been interested in ferns and as there seems to be a lot fewer species than flowering plants I somehow hope they might be a bit easier to identify. So I am starting literally at home, in this case just outside my front door where there is a single plant of Maidenhair Spleenwort growing out of the front garden wall. This is a common fern found not only throughout Britain but the World.
Maidenhair Spleenwort (Asplenium trichomanes) is commonly found growing in older mortared walls along with Wall Rue (Asplenium ruta-muraria).
‘Throughout much of Britain and Ireland, the usual form of Asplenium trichomanes to be found in these habitats is its subspecies quadrivalens…’ (Page, p 142).
So straight away its not quite so simple, I presume my fern is ssp quadrivalens but I suppose I should really find out!
