This large fern grows in clumps on limestone cliffs. Its leaves can reach lengths of over 1 m and exhibit a distinctive feather-like appearance with numerous branches. As suggested by its Japanese name, "Taiwan-amakusashida," it is found in Taiwan, with Tokunoshima being its only habitat in Japan.

While there are also high mountains in Tokunoshima Island, there are also plateaus formed by raised coral reefs surrounding such mountains. These plateaus, with base rock made of Ryukyu limestone, formed a complicated terrain as a result of erosion. Forests growing on such plateau are made of plants preferring limestone soil, and this is one of the important factors characterizing the nature of Tokunoshima Island.
