Cryptogramma cascadensis is a species of fern known by the common names Cascade parsley fern and Cascade rockbrake. It is native to western North America from British Columbia to Montana to California, where it grows in the cracks and crevices of mountain talus slopes, especially in moist subalpine areas on volcanic or granite rocks. The plant forms a clump from a rhizome. It has two types of leaves. The sterile leaf is flat with lobed oval or diamond-shaped leaflets, and the fertile leaf is longer, with narrow, thick, fingerlike leaflets with edges curled under to cover the sporangia on the undersides.
