Swartz, Syn. Fil. 129, 332.—Rhizome very short, suberect, clothed with silky scales. Stipes 3–9 in. long, tufted, wiry, erect, dark red-brown, smooth and polished, glabrous or slightly scaly when young. Fronds 4–10 in. long, 2–4 in. broad, deltoid or ovate-deltoid, submembranous, yellowish-green, 3-pin-natifid; rhachis smooth, polished, glabrous or nearly so. Primary pinnæ 6–12 on each side, opposite or nearly so, ascending or spreading; the lowest pair sometimes 2½ in. long, deltoid; the upper smaller and narrower. Pinnules oblong or elliptic-oblong, deeply pinnatifid; ultimate segments entire or irregularly lobed or crenate; surfaces glabrous. Sori on the margins of the lobes, generally confluent and continuous all round the edge of the pinnules. Indusium narrow, elongated, usually crenate or denticulated, often transversely wrinkled.—
