Maiden’s hair, Asplenium trichomanes.
Both the scientific name and another common name “spleenwort” are derived from an old belief, based on the doctrine of signatures, that the fern was useful for ailments of the spleen, due to the spleen-shaped sori on the backs of the fronds. “wort” is an ancient English term that simply means “plant”.
