Stems horizontal, short-creeping. Petiole straw-colored, 1–3 times length of blade, hairs absent abaxially, pubescent adaxially, base scaly; scales lanceolate to linear, 1–3 × 0.3–0.5 mm. Blade deltate to pentagonal, 1-pinnate or ternately lobed, 5–10 × 3–7 cm. Rachis and costae pubescent abaxially. Pinnae absent or 1(–2) pair, or blade shallowly pinnatifid, 4–7 cm, base rounded, without proliferous buds in axils. Areoles rarely with included veinlets. Indusia peltate. 2n = 80.
Habitat: Sinkholes, on shaded ledges or occasionally in sun
Elevation: 0 m
Distribution
Fla., Mexico in Yucatán, West Indies in Bahamas, Greater Antilles.
Discussion
The hybrid between Tectaria fimbriata and T. coriandrifolia is T. × amesiana A. A. Eaton. Although intermediate between the two parents, the hybrid will lead to T. fimbriata in the key. The hybrid may be distinguished from T. fimbriata by scattered hairs on abaxial surface of petioles and misshapen spores.
