Happy Fern Friday!

Two fabulous ferns from James Britten's European Ferns (1879-81). On the left is the Hart's Tongue Fern (Asplenium scolopendrium), and on the right is another spleenwort (Asplenium sagittatum).

These ferns were commonly called "spleenworts" because they were thought to treat disorders of the spleen based on the "Doctrine of Signatures", which held that plants that resembled the shapes of body parts were meant to treat ailments of those body parts.
