Ophioglossum vulgatum - Adders Tongue


Population 3 - Hutton Roof
(fertile)

This is the most prolific population, and is found to the North West side of Hutton Roof, and at the side of a well trodden footpath. Their are hundreds if not a thousand or so, covering an area of about a metre wide and over a distance of 18 metre (20 yards) intermittent. The plants are well shielded by emerging bracken. I found the population on 14th May 2020.

Population 2 - Burton Fell
(infertile)

Now we have another fern from yesterday and showing nice emergence photographs, this time the Ophioglossum vulgatum (Adders Tongue Fern).  To my knowledge so far this is only the 2nd population so far found on Hutton Roof Crags. I have checked out this population in both 2019 and 2020 and although you get the shoots and growth of the large leaves you do not get the column, so obviously I have taken it that these plants are infertile.
