Skye Botany Group – Ferns and Fern Allies

Skye Botany Group is undertaking a project with the Darwin Tree of Life project. We will be recording Polypodium (Polypody) species and a hybrid (we hope) plus two species of Ophioglossum (Adder’s-tongues). On Wednesday we had a day with pteridologist James Merryweather to look at his local polypodies and also Dryopteris species on the nearby Scottish mainland, including D. lacunosa.

We were able to see Polypodium interjectum (Intermediate Polypody), P. vulgare (Polypody) and their hybrid P. x mantoniae.

Later: Having examined the spores microscopically, we are not certain that we saw the hybrid.

Polypodium x mantoniae (Maybe)

There are only two records of the hybrid in VC104, one on Rum that we were unable to confirm during the Flora of Rum project and one near Struan on Skye. We feel there must be more and expect that our project will allow us to assess this properly.

The principal objectives regarding Ophoioglossum are to see if it can be found on Skye north of Portree and to seek more sites for O. azoricum. The latter is quite widespread on Raasay but only four sites are known on Skye of which three are on the north coast of Sleat.
