Characteristic

A large perennial herb that the height is over 1 m and the leaf length is as large as 2 m. However, in the winter near the distribution area the ground portion withers.

Rhizomes stand short and obliquely, and sprinkle reddish brown scales sparsely. The petioles are almost upright, 1 m in length, reaching the thumb large in thickness, coloring from reddish brown to dark purple, glossy. There is scales at the base.

Is only in the leaf part and overpasses 1 m. It is divided into three at the tip of the petiole, and since it also branches out from the base of the side branch toward the base direction, the whole is pentagonal and it opens almost horizontally. Feather pieces in the form of feathered biloba are attached once to each branch, and those of the main axis are the largest, and those of the side branch branches are slightly small. Leaf quality is grassy and green.

The small pieces constituting the wing pieces are torn deeply like feathers, and the tip becomes a somewhat longer apical piece. Lateral fissures are linear lanceolid shapes and somewhat sickle shaped towards the tip, 1.2-2 cm in length and 2-4 mm in width. The edges of the sporangium-free part have fine serrations. The sporangia group grows long on the side of this lacunae, and it breaks at the base and the tip. It is wrapped in a false envelope consisting of entangled leaves. In addition, the vein connecting the midbrain base of the fissure has a characteristic of forming a mesh around the middle pulse of the small leaf.

It is known that it contains various substances as special ingredients.

Distribution and habitat environment

In Japan, it is distributed from Honshu, west of Chiba Prefecture, to the south of Shikoku, from the Kyushu to the Ryukyu Archipelago, from the tropical subtropics in Asia to the Samoa in the east.

It emerges in places with a lot of water in the mountains, often making big communities. It also appears quickly in places that have received ecological disturbances (cherries), often seen in roadside and collapsed places.

Classification

About 250 species are known worldwide in this genus, and 26 species are reported in Japan. In Japan, there is no other large species that will be pentagonal like this kind. Also, other types of ferns are few such forms, and are easy to distinguish because of their large size.

When only wing pieces are taken, they are similar to the same belongings, but can be distinguished by the characteristics of the leaf veins described above.

Use

There is an area to eat sprouts. But as it is edible, and cattle and deer do not eat this, make a large community along the valley of pasture land. This is common to several species of edible fern in this area, but since none eat because they contain toxic components, they grow well as fertilizer of livestock discharges around grazing land. Human beings can be edible by plucking their sprouts in a special way, and a system is established that can obtain good ingredients.

protection

It is known as warm ferns in the mainland of Japan. It is designated as a natural monument of the country as Natsushida native northern limit. However, in reality this is not a northern limit.

Although not listed on the Red List of the Ministry of the Environment, it is designated as endangered in the eight prefectures in the northern region, especially Kanagawa and Fukui prefectures are designated as endangered I class. Beyond that it is relatively normal.
