description
The French striped fern is a perennial herbaceous plant and reaches heights of 10 to 20 centimeters. The fronds are divided into a petiole and a leaf blade. The leaf stalk is shorter than the leaf blade and the stalk is brown up to the rachis . The rachis is green. The double to triple pinnate leaf blade is linear-lanceolate in outline and hardly or not at all narrowed towards the base. The lowest pair of plumage is often directed downwards and backwards. The leaflets are angularly serrated. The sori stand away from the edge.
The spores are ripe from July to September.
The number of chromosomes is 2n = 144.
