Two of the three selected species [Macrothelypteris torresiana and
Thelypteris dentata) belong to the 22 species introduced into Mexico (Tejero-Diez and Torres-Diaz, 2012), and both are weedy and more abundant in ruderal habitats than the native species (Blechnum appendiculatum).

This high generic species richness is surpassed only by Asplenium and
Thelypteris (44 each), which both include only one new record in addition to Mickel and Smith (2004), just like Polypodium (30) and Selaginella (28), the latter being another genus with four doubtful species.
