Leaves: Fronds 5-30 cm, on brown petiole, equal to or somewhat longer than blade, rounded above, glabrous except for a few scales at base, blade broadly pentagonal, deeply pinnatifid, but not fully pinnate above base, upper pinnae connected by narrow wing of green tissue, 1-2 times longer than wide, conspicuous yellowish powdery covering below, scales absent, glabrous above, basal pinnae much larger than adjacent pair, strongly unequal, upper pinnules greatly enlarged. Sporangia: Dark brown, dull, with 32 or 16 spores, sori continous along magins of weakly revolute segments. Ecology: Found in rocky canyons, along cliffs, and among rocks from 1,000-6,500 ft (305-1981 m); sporulating late spring to fall. Notes: Distinguished by the bipinnatifid blade that is not divided into separate segments.
