Botany
Dryopteris heterocarpa is a terrestrial fern with short, stout, creeping rhizomes clothed with brown scales. Stipes are tufted, scaly at the base and 30 to 50 centimeters long. Fronds are large, 30 to 90centimeters long. Pinnae are linear-lanceolate, sessile, and 1 to 2 centimeters wide. Rachis and lower surface of the leaves are hairy, particularly on the veins, and are densely covered with yellow glands. Sori are medial, few or 6 to 9 on a side. Indusium is small.
