Pyrrosia Polydactyla

Description

Pyrrosia Polydactyla, commonly known as the ‘Finger Fern,’ is a unique fern species that belongs to the Polypodiaceae family. It is native to Japan, China, and Taiwan and can be found growing on trees or rocks in shaded areas. The fern produces elongated fronds that can grow up to 30 cm in length and 5 cm in width. Each frond has a slightly hairy texture and is divided into leaflets that resemble fingers, hence its common name. The fern is an epiphyte, meaning it grows on other plants, and does not have any roots that anchor it to the ground.

Taxonomic Information

Appearance

The Pyrrosia Polydactyla fern has a unique appearance that makes it easy to identify. Its elongated fronds have a slightly hairy texture and are divided into leaflets that resemble fingers, hence its common name. The fronds are a bright green color and can grow up to 30 cm in length and 5 cm in width.
