Description:

  • A smaller, light green fern of cool, moist places.
  • Fronds monomorphic, deciduous, and solitary from creeping rhizome; leans backward; 4"-20" tall.
    • Petiole (leaf stalk) straw-colored, 6"-14", with light brown scales.

    • Pinnae nearly opposite and sessile (lacking stems), deeply cut but not all the way to the stem, with smooth edges.
  • Rootstalk long-creeping, slender, and branching.
    • Roots black, wiry, and branching; often quite numerous and growing deep into the soil.
  • Sori small, on underside of leaflet near edges; lacking indusium.

  • Unmistakeable due to its distinctive and easily observed drooping pair of lower leaflets.
