It looks like my Polypodium cambricum?

It has quite a leathery leaf and the new leaves are pinkish in colour. I have ordered the RHS Wisley Handbook on Ferns.

I'd have said p. cambricum, by the distinct triangle of the whole leaf. Great group of plants, the ferns, so useful where other plants struggle, and very attractive in their own right. Overlooked too often

Could it be Cyrtomium fortunei var. clivicola? The leaf is dark and as I said leathery. I saw it at Culzean Castle last week but it had no name.

Just joining in for more info please -I don't know Cambricum,( it's vulgare that grows round here) but the other polypodies are not so shiny, so toothed or leathery. Is this a variety limited to limestone? It isn't in my rather limited fern book.

I await my RHS book with anticipation Steragram. I wish I had found out its name at Culzean. The young leaves are a kind of terracotta colour, then the get greener as they mature. You can see a bit of it at the tip of the centre leaf.

Its certainly attractive .Let us know what the RHS says.

There is a gallery of 40 named ferns on Wikipaedia.

I did look Diane but couldn't decide which one. My book has been dispatched so not long now.
