The Female Fern

The female fern (Athyrium filix-femina) is a sail boat from the female family (Athyriaceae). The plant is found in the northern hemisphere. The plant is also used in the ornamental garden.

The pale yellow-green leaves are 30-50 cm long. The length of the foot purple-brown leaf stalk is one fourth that of the leaf. The leaf blade is elliptical in outline and tapering about two to three times or suspension parts. The leaves die in winter. In the spring from the rootstock (rhizome), the new leaves.

Like the male fern are the spores (sori), which consist of sporangiƫn in two rows. The dekvlies (indusium) is usually hooked. In July and August are the spores mature.

The female fly has no close relatives of the same sex in Belgium and the Netherlands.

There is potential for confusion with the equally widespread male fern (Athyrium filix-mas) and the rare fern dotted (Oreopteris limbo semen) is. All three have similar habitat and similar characteristics. The female fly is both distinguished by the shared triple blades and the comma-shaped hook or spores. The other two have shared double blades and tapeworms.
