  • Discussion

    Specimens examined: Mpio. Othon P. Blanco, Kohunlich, in 1988, G. Cortes s.n. (XAL).

    Previously known from Mexico (Veracruz, Oaxaca, Chiapas, and Tabasco), Guatemala, and Belize to Costa Rica, Antilles, Trinidad, Tobago, Venezuela, and Colombia to Peru and Brazil.

    Adiantum villosum is very similar to A. latifolium Lam. The former has a stout, short-creeping rhizome, and the latter a long-creeping rhizome. Specimens without rhizomes are sometimes difficult to distinguish; however, A. latifolium is glabrous on the pinnules abaxially, often more glaucous, and the sterile pinnules are evenly serrulate (Smith, 1981).
