| 1. | Sori are round and covered in a bladder-like indusium.
|
| 2. | Sori may be covered by a structure called an indusium.
|
| 3. | Initially, indusium and scale molecular phylogeny of the Cyatheaceae is refined.
|
| 4. | The distribution, size, color, and indusium length.
|
| 5. | The sori are covered in a kidney shaped indusium which is smooth.
|
| 6. | The presence or absence of indusium is also used to identify fern taxa.
|
| 7. | As the sporongia mature, the indusium shrivels so that spore release is unimpeded.
|
| 8. | Receptacle protrudes from the indusium as in all " Trichomanes " species.
|
| 9. | They are covered by a prominently whitish to brown reniform ( kidney-shaped ) indusium.
|
| 10. | The sori, which lack a true indusium, within the inrolled margins of the pinnae.
