| Thus it is proper to describe the shape of the indusium as peltate. |
| The latter is covered by the indusium griseum, a thin sheet of rudimentary cortex containing the delicate medial and lateral longitudinal striae. |
| Loss of indusium, dimorphism, areolate venation, and reduced blade dissection have occurred repeatedly along many evolutionary lines in Dryopteridaceae. |
| The indusium is orbicular-reniform, and almost always smooth. |
| Yesilyurt segregated this species based on its filiform segments, pinnate division, and crenulate indusium margins. |
| The sori are quickly confluent, and all trace of the indusium is soon lost. |
