Stems decumbent, compact. Petiole tan to reddish brown, often shorter than to rarely equaling blade, pubescent on both surfaces, scaly; scales narrowly deltate or lanceolate, 2–5 × 0.1–0.2 mm. Blade lanceolate to oblong, 1-pinnate-pinnatifid, 5–12 × 2.5–10 cm. Rachis and costae pubescent abaxially. Pinnae 1–8 pairs, margins crenate to pinnatifid, 1.2–5 cm, base rounded, often with proliferous buds in axils. Areoles lacking included veinlets. Indusia round-reniform, attached at sinus. 2n = 80 (Jamaica).


Habitat: Sinkholes, rock, ledges, crevices
Elevation: 0 m

Discussion

Tectaria coriandrifolia is known in North America only from southernmost Florida; it has not been seen there for several years and is perhaps extirpated. It hybridizes with Tectaria fimbriata to form T. × amesiana A. A. Eaton [Aspidium trifoliatum (Linnaeus) Swartz var. amesianum (A. A. Eaton) Clute], which may be distinguished by its misshapen spores, fewer pinnae pairs, and dense row of hairs on the adaxial surface of the petioles. The hybrid is known only from Florida.
