''Cryptogramma crispa'', the parsley fern, is an Arctic–alpine species of fern. It produces separate sterile and fertile fronds, up to tall, and is a pioneer species on acidic screes. ==Description== The fronds of ''C. crispa'' are long and appear in two distinct forms. Sterile leaves are 2–3-pinnate with the pinnules long by wide, while fertile leaves are 3–4-pinnate, and with narrower pinnules. The fertile leaves have sori scattered along the veins, each with a strongly enrolled false indusium. The sporangia are yellow and mature around midsummer.〔
