Sori very numerous, crowded, often encircling the whole of the margin of the frond. Indusium narrow cup-shaped or almost bell-shaped. Receptacle far-exserted, stout columnar, covered with sporangia.—''A. Rich. Fl. Nouv. Zel. 95; A. Cunn. Precur. n. 228; Raoul, Choix, 38; Hook. Sp. Fil. i. 115; Exot. Ferns, t. 2; Hook. and Grev. Ic.

Segments simple or dichotomously branched, linear, obtuse, flat, minutely denticulate; margins ciliated with branched rufous hairs. Sori few or many to a frond, deeply sunk in the tips of the segments. Indusium obconical, the width of the mouth about equalling the depth of the tube; margins ciliated, not dilated nor bordered.
