I was down at Dawlish Warren yesterday – in one of the dune slacks close to the visitor centre I found an Adder’s Tongue Fern – once I got my eye I could see hundreds of them. Never seen so many before anywhere!
To those people who have never seen an Adder’s Tongue Fern before I suspect most would not recognise it as a fern at all.
Adder’s Tongue Ferns are plants of unimproved grassland and are usually pretty difficult to find as they blend into the similarly coloured grassland. There are three species in the UK – two very rare and this one which is more abundant but not at all common. The Latin name for the genus is Ophioglossum. It comes from the Greek ophis which is a snake and glossa which is the tongue.
I’ve always found this description rather baffling as snakes (and adders in particular) have forked tongues…..
I guess the spore bearing stalk resembles a snake tongue before the fork!
