Lindsaea quadrangularis subsp. mexiae Mickel, Mem. New York Bot. Gard. 88: 367, f.173 A-C. 2004
Type. Mexico. Jalisco: West of San Sebastian, Hacienda del Ototal. Arroyo de Los Hornos, Mexia 1837 (holotype NY!; isotypes F!, G, GH!, MICH!, MO!, UC!, US!).

Ab varietatibus aliis L. quadrangularis segmentis arcuatis 5–6 mm abiens.
(Honoring Ynes Mexia, who made many important collections of Mexican ferns.)

Distribution. Shady streambanks; 1500 m. Known only from the type collection.

Kramer (1957) considered this to be L. stricta f. moritziana (Klotzsch) Kramer, but its characters match those of L. quadrangularis much more closely.

Lindsaea quadrangularis subsp. subalata K.U.Kramer, Acta Bot. Neerl. 6: 190, f.50. 1957
Type. Costa Rica. El General, Skutch 2241 (US!; isotypes GH, MO, NY!).

Distribution. Terrestrial in wet forests; 0–1000(–1400) m. Mexico; Guat, Bel, Hond, Nic, CR, Pan; Cuba; Col, Ven.

Specimens Examined. Chis (Breedlove 21891, DS). Oax (Hernández G. 1676, 2035, 2536, 2675, NY; Martínez C. 415, UC, US; Mickel 6517, NY). Ver (Nee et al. 25042, XAL; Smith 2078, MO p.p.).

Unverified, Doubtful, or Mistaken Reports. Gro (Campos 1692, FCME, cited by Lorea-Hernández & Velázquez M., 1998, but not verified).

Mickel and Beitel (1988) mistakenly reported subsp. antillensis Kramer from Mexico (Ver, Oax, Chis) and Central America, but these specimens belong to subsp. subalata.
