Sterile fronds erect, 15-30 cm. long; stipes pilose, dull-stramineous from a darkish base, concavemarginate along the anterior face, convex below ; lamina orbicular (the divisions spreading), 10-12 cm. broad, in drying conduplicate and broadly obdeltoid, 5-8 times dichotomous, the ultimate divisions linear, 1-2 mm. broad, acutish, unicostate, the costa elevated above, scarcely so below, the margins thickened and conspicuously scabrous at the upper surface. Fertile fronds stouter, 30-50 cm. long, 3 or 4 times dichotomous, the ultimate divisions slender; sporangiophores strongly incurved (straight at first), 1.5-2 cm. long, conduplicate, the segments (15-25 pairs) slender, the middle ones distinctly the longest, the margins and costae pilose ; spores delicately and very minutely verrucose.
