Polypodium cambricum 'Hornet'

This unusual form of the Welsh polypody is one funky little dude. Pinnate fronds marked by pinnae of irregular length make it look as if it has undergone a friendly nibble from time to time, and each pinna is made yet more bizarre by a midrib that extends past its natural end to form a barb-like appendage akin to the stinger of its less amiable namesake. For the lover of botanical oddities (don't worry you are in good company) this is no doubt an absolute must have!
