Ultimate segments 2–4 mm wide; margins ciliate. Veins 3–6 pairs per segment, unbranched or 1-forked.

Discussion

The names Ctenitis ampla (Humboldt & Bonpland ex Willdenow) Ching and Dryopteris ampla (Humboldt & Bonpland ex Willdenow) Kuntze have been misapplied to this taxon. Ctenitis sloanei and C. submarginalis both have numerous scales at the base of the petiole; in C. sloanei, however, the scales form a large, conspicuous, tangled tuft.
