VIVERO-BARON, Janet; ARREGUIN-SANCHEZ, María de la Luz; QUIROZ-GARCIA, David Leonor  and  FERNANDEZ-NAVA, Rafael. Athyrium palmense (Christ) Lellinger and Athyrium skinneri (Baker) Diels (Athyriaceae-Pteridophyta), new proposal for their delimitation. Polibotánica [online]. 2010, n.30, pp.43-54. ISSN 1405-2768.

Athyrium palmense (Christ) Lellinger and A. skinneri (Baker) Diels were studied in detail in an attempt to clear up long-standing confusion in their taxonomic delimitation. A study was undertaken of the external morphology of the sporophyte, anatomy of the rhizome and frond, and spore morphology of 60 specimens preserved in Mexican herbaria. Because the characters purporting to distinguish the two species were considered insufficient, A. palmense was placed in synonymy under A. skinneri, the name having priority.

Keywords : Athyriaceae; Athyrium palmense; Athyrium skinnneri; delimitation; pteridophyta.
