Scolopéndrium. Phyllìtis
Sori linear, a row on either side of the midvein, and at right angles to it, the indusium appearing to be double. (Scolopendrium is the Greek for centipede, whose feet the sori were thought to resemble. Phyllitis is the ancient Greek name for a fern.) Only one species in the United States.
