- The Ryukyu Islands(south of Tokunoshima), Taiwan, China, Southeast Asia, India, Sri lanka, and south Pacific islands
In the diorama, it grows along with other limestone-favoring plants.
This fern is found in regions south of Tokunoshima. Its Japanese name, "Nanabake-shida," meaning "seven changes," refers to the variety in its leaf shapes. The vegetative (trophic) leaves appear flat and smooth, while the fertile leaves are noticeably textured, with bumps where the spore clusters are located, making them visible from the upper side.
Habitat of This Animal:
A:Forest along the valley - A1:Accessible forest
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.
