This medium to large fern is commonly found in the forests of Tokunoshima. Its leaves can reach approximately 70 cm in length, and true to its name "Katsumou" (meaning "brown hair"), the leaf stalks are covered with brownish, hair-like scales. In slightly drier areas of the forest, it can sometimes form large clumps, making it difficult to see the ground beneath, which can be unnerving as habu vipers may be present.

Habitat of This Animal:
A:Forest along the valley - A3:Deep forest
Along the mountain valleys grows a high humidity forest. In such an environment, Quercus miyagii, a species of oak often grows in clusters. Some of these grow more than 20m tall and with trunk diameters exceeding 1m, with largely developed buttress roots. Also, there are many animals and plants preferring humid environments, supporting the abundant biota of Tokunoshima Island together with the forest along mountain ridges.
