  • Discussion

    Syntypes. Guadeloupe. “Ma-touba, Ravine Flore, Rivière Goyave,” 1861, l'Herminier s.n.; Martinique. Mile. Rivoire s.n. (P?). Hymenophyllum fucoides and H. ectocarpon belong to a complex in need of study. The latter is distinguished by the deeply laciniate indusial margins and stipe less than 2 cm long. Although specimens from Oaxaca fit the description for H. ectocarpon, both A. R. Smith (1981) and Stolze (1976) report the taxon from low elevations (3001200 m) whereas in Oaxaca it occurs at high elevations.

  • Distribution

    Epiphytic in cloud forests; Ixtlán, Teotitlán; 2150-2700 m. Mexico (Oax, Chis); Guat to Pan; L Antill.
