This fern, as can be seen from the 1st photo, colonized a shadecloth canopy. (The canopy collapsed a few years ago and a substantial amount of leaf litter has accumulated in the depression formed in the top, with several ferns & other plants colonizing the underside).
The 1st photo, (2025-01-09) provides context. The 4 other photos were taken on 2024-10-23, 2025-01-01 (2 of), and 2025-01-26, respectively.
