The frondlets have their points turned down to form spore cases.

On the return of moisture, the spore cases softened, become mucilaginous, and discharge their contents to form a fresh crop of plants.

After the water dries up, the plants die, and leave the spore cases on, in many instances quite covering the surface of the dried mud.
