Description:
Species Description - Rhizome suberect; rhizome scales brown, clathrate, 5-9 mm long, 1.5-3 mm wide, with occasional teeth fronds clumped; stipe 25-30 cm long, ½ the frond length, brown, dull, with numerous narrow, twisted clathrate scales, 3-4 mm long; blade once-pinnate, not reduced at base, 25-35(-60) cm long, 10-25 cm wide, apex subconform, non-proliferous; rachis green to brown, dull, with scattered scales (often three-parted; 1.52 mm long), narrowly winged; pinnae 6-14 pairs, petiolulate, lanceolate, 6-12 cm long, 1.5-2.5 cm wide, attenuate, base inequilateral, excavate ba-siscopically, roundish auriculate, crenate, serrate or biserrate; veins 1-2-forked, not reaching margin, hydathodes present; sori 10-12 pairs, short, oblique; indusia 3-5 mm long, 1.5-2 mm wide, vaulted, whitish.

Discussion:
Type. Mexico. Galeotti s.n. (P, not found). Asplenium sanguinolentum Kunze ex Mettenius, Abh. Senckenberg. Naturf. Ges. 3: 186, t. 4, f. 10. 1859. Lectotype (chosen by Morton & Lellinger, 1966: 10). Brazil. Beyrich s.n. (L). Asplenium feei is not known from any Oaxacan collections specifically, but the type collection (Galeotti) only says “Mexico,” which could mean Oaxaca, Veracruz, México or Puebla. Thus, it is known from both sides of Oaxaca, if not Oaxaca itself. The larger frond size, numerous scales on the stipe and rachis, long and common rhizome scales (5-9 mm long), and short and wide indusia (35 mm long, 1.5-2 mm wide), will distinguish A. feei from A. tuerckheimii and A. repandulum, both of which have subconform terminal pinnae. Asplenium repandulum has a creeping rhizome, veins to the leaf margin and a smaller (6-8) number of pairs of sori, whereas A. tuerckheimii has fewer pinnae (3-6), each with an equilateral base. Asplenium anisophyllum Kunze (Linnaea 10: 511. 1836) from tropical Africa resembles this species closely, and may well be conspecific. If this is the case, then the name A. anisophyllum has priority.
