Description
The plants are unusual in being ferns with simple, undivided fronds. The plants grow on neutral and lime-rich substrates, including Prefers Wet Soil and damp crevices in old walls, most commonly in shaded situations but occasionally in full sun; plants in full sun are usually stunted and yellowish in color, while those in full shade are dark green and luxuriant. The tongue-shaped leaves have given rise to the common name “Hart’s tongue fern”. The sori pattern is reminiscent of a centipede’s legs, and scolopendrium is Latin for “centipede”.
