After a frustrating few years of looking for it, the enigmatic Adder's Tongue Fern (Ophioglossum vulgatum) has finally revealed itself! Having always looked for it on the less populated parts of the Marshes over the years, it's dumbfounding how it has recently been found so close to where many people drop their trash, scar the earth it grows on with bbqs, 'professionally' walk their army of dogs and almost definitely and routinely trample over it. Uncommon and an indicator of ancient meadows; its discovery on Walthamstow Marshes contributed to helping save the Marshes from redevelopment in the 70s and also forms part of the basis for the Marshes' SSSI status. It’s tiny and delicate - the size of your thumbnail. Currently, there are quite a number of them.
