Descripción
Roots wiry, fibrous, not proliferous; rhizomes erect; rhizome scales brown, clathrate, tips long-attenuate, 3–6 X 0.5–0.8 mm, entire; fronds clumped, 30–60 cm long; stipes gray-green to graybrown, 4–12 cm X 1–2 mm, 1⁄5–1⁄3 of frond length, glabrous, with green wings 0.5 mm wide, at least distally; blades 25–45 X 4–10 cm, 1-pinnate with pinnatifid, nonproliferous apices, 2–3 pinna pairs slightly reduced proximally; rachises gray-green to gray-brown, glabrous, with greenish wings 0.5–0.8 mm wide; pinnae oblong to lanceolate, 14–25 pairs, 2–3 X 0.8–1.5 cm, bases of basiscopic margins excavate, bases of acroscopic margins usually curved, often overlapping the rachises, apices obtuse to subacute, margins serrate to biserrate with obtuse to subacute teeth, sinuses mostly 1–3(–5) mm deep, deepest sinuses separating acroscopic basal lobe; veins evident, 1-forked on acroscopic sides of pinnae, distal and basiscopic veins simple, tips evident adaxially; indument absent, blades essentially glabrous; sori 2–6(–14) on basiscopic sides, 4–10(–17) on acroscopic sides, (0–)1 or 2 diplazioid sori on basal vein; indusia 3–5(–8) X 0.5–0.8 mm, margins entire to subentire; spores reniform.A

Discusión taxonómica
Both specimens of A. williamsii cited by Palacios-Rios (1992) from Veracruz are other species in this complex: Finck 50 (NY) is A. miradorense, and Bourgeau 2369 (NY) is A. potosinum. Several of the collections cited as A. williamsii by Mickel and Beitel (1988) are also A. miradorense: Mickel 1535 (NY, US); Mickel 7306 (NY); Hallberg 1551 (NY). The stated elevation for A. williamsii in both references is consequently too low.
Mexican specimens of A. barbaense generally have less attenuate, shorter pinnae than most specimens from Costa Rica and Panama, and it is slightly uncertain whether plants from the two areas are conspecific. Adams (in Davidse et al., 1995), was the first person to unite them. Asplenium barbaense is distinguishable from the closely related A. miradorense by the dull gray-green stipes that are alate to the bases, broadly alate rachises (wings 0.5–0.8 mm wide), longer rhizome scales (4–6 mm), longer sori (3–5 mm), and acroscopic bases of pinnae strongly overlapping the rachises. The two species may grow together (compare, e.g., Mickel 6582, 6719 (NY), both A. miradorense in Oaxaca). See discussion under A. potosinum for comparison with that species.
Asplenium diplosceum Hieron. (Hedwigia 60: 232. 1918; Cuba, Wright 849, B, isotype BM!) of Cuba, Hispaniola, and Jamaica resembles A. barbaense closely. If they prove to be conspecific, A. diplosceum has priority; Adams (in Davidse et al., 1995: 399) regarded them as distinct, but did not elaborate as to his reasons.
