Asplenium trichomanes, Maidenhair Spleenwort: Mystery Fern Appears on Limestone wall in Fern Valley

There are no records, and Joan has no memory of them. They must have been there all along (translate to 20-50 years) and just passed as small Ebony Spleenworts. The abundant moisture of the last 18 months has allowed them to grow to a size where their true identity is unmistakable. It's a nice little fern that grows on rock faces and is native throughout the US excepting the prairie states.
