Frond rhomboid, 4-pinuate, 6 in. long; pinnæ and pinnules ascending, rhomboid, stalked, the lowest the largest, cuneate-truncate on the lower side at the base; final segments ligulate-cuneate, 2–4 lines long, under ½ line broad; texture subcoriaceous; surfaces naked; sori minute, terminal, with the lamina produced on each side as a border."—Bak.

3. D. novæ-zealandiæ, ''Col. in Tasmanian Journ. Nat. Sci.'' (1845) 22.—Rhizome long, branched, wide-creeping, as thick as a quill, clothed with yellowish-brown linear scales. Stipes 6–18 in. long, red-brown, firm, erect, rough and bristly at the base, smooth and polished above. Fronds 1–2 ft. long, 6–12 in. broad, ovate-oblong to deltoid, acuminate, firm but scarcely coriaceous, tripinnate; rhachis flexuose, channelled above, glabrous or pubescent at the axils. Primary pinnæ oblong-lanceolate, acuminate; secondary about the same shape, pinnate below, pinnatifid at the tips. Pinnules about ½ in. long, ovate-lanceolate, deeply pinnatifid; ultimate segments or lobes very narrow, acute. Sori very numerous, placed at the tip of a short lateral veinlet on the lobes of the pinnules. Indusium broadly ovate or almost orbicular, membranous, jagged, attached to the tip of the vein under the sorus, its sides quite free.—''Hook. Sp. Fil. i. 158, t. 51b; Garden Ferns, t. 51; Hook. f.
