Sterile leaves are without stalks, nearly circular and about 1 cm across, fleshy and have a smooth surface. Fertile leaves have a stalk of about 1 cm in length and are elongated, 3 - 12 cm by 5 - 8 mm.
      Reproductive Parts (non-flowering plant): The sori are arranged in a broad band along the edge of the leaf and may be about 2.5 mm wide when mature.
