Thelypteridaceae
Species Description - Rhizomes short-creeping, ca. 1 cm diam.; fronds monomorphic or nearly so, 50–100 cm long; stipes glabrescent, 15–50 cm x 2–5 mm; blades 20–40 x 18–30 cm, 1-pinnate; pinnae 2–6 lateral pairs plus a conform terminal pinna, 12–22 x 3–6 cm, subentire or crenate or coarsely serrate, rarely shallowly lobed, the proximal ones sometimes gemmiparous in the axil, proximal ones mostly short-stalked, subcuneate at the bases, distal ones sessile and truncate or rounded; segments absent, or the shallow lobes 4–6 mm wide; veins meniscioid, with 6–9 pairs of second ary veins, the lower 3–5 pairs upcurved and acutely united with a free excurrent veinlet, usually the next few pairs alternately united in a common veinlet running to the sinuses; indument abaxially of mostly acicular hairs ca. 0.3–0.5(–1) mm long on rachises, costae, veins, and tissue between veins, adaxially the blades with similar hairs; sori in a double row between the costules, exindusiate; sporangia with 4–6 acicular setae 0.1–0.3 mm long; 2n=144 (Jam, Oax, Trin).

Unverified, Doubtful, or Mistaken Reports. QR (Castillo R. & Tun G. 220, UADY, XAL, cited by Palacios-Rios, 2002c, but not verified). Thelypteris poiteana differs from T. ghiesbreghtii by the presence of buds at bases of proximal pinnae, fewer vein areoles between costae and pinna margins, somewhat shorter hairs on the blades abaxially, and setose sporangia. Castillo Rivero 94, the sole collection from Yucata´n, differs from most members of the species in having the costae and blades sparsely hairy; otherwise it is typical.
