The rusty-back fern gets its name from the rust-coloured scales which completely hide the underside of the leaf. Each leaf is about 2 - 4 inches long. The plant is usually found growing in the joints of mortared stone walls, old buildings or bridges. It is fairly common.
All names: Ceterach officinarum DC.; Asplenium ceterach L.; Ceterach ceterach (L.) Newm.
