Orthiopteris

Description

Orthiopteris, commonly known as the shield fern, is a genus of ferns in the family Dryopteridaceae. They are native to Asia, Africa, and the Americas. The name Orthiopteris is derived from the Greek words “ortho,” meaning straight, and “pteron,” meaning wing, which refers to the straight-edged shape of the leaves.

Taxonomic Information

Appearance

Orthiopteris has evergreen fronds that grow in a symmetrical pattern. The leaves are lance-shaped and have pointed tips, with a glossy green color on the upper surface and a lighter green on the underside. The fronds can grow up to 3 feet long and 1 foot wide, and they have a distinctive straight edge that gives them a shield-like appearance. The leaves are arranged in a rosette formation at the base of the plant, and the spores grow on the undersides of the fronds in small clusters.
