Appearance
Arachniodes ferns have fronds that are pinnate or bipinnate, with a glossy texture and a dark green color. The fronds are typically 20 to 60 cm long and 10 to 30 cm wide. The spore-bearing structures called sori are located on the underside of the fronds and are covered by a protective flap of tissue called an indusium. The sori are arranged in a circular or linear pattern and are often grouped in clusters. Arachniodes ferns can be distinguished from other ferns by their unique sori and indusia.
