Phylogenetic placement and characterization of Adiantopsis alata Prantl, a neotropical fern with a murky taxonomic history.

The fern species Adiantopsis alata was named and described by Karl Anton Eugen Prantl in 1883. He based his definition of the species on two plant specimens, one collected by Bernhard Luschnath in Brazil and one collected by Sir Robert Hermann Schomburgk in Guyana. Research in the Link-Pérez lab has confirmed that the Luschnath and Schomburgk specimens actually represent two different species. Currently, the Link-Pérez lab is describing several new species of Adiantopsis from the Guyana Shield, one of which includes the Schomburgk specimen. Therefore, our research group will be selecting the Luschnath specimen as the lectotype for A. alata. Morphological studies and molecular phylogenetic analysis of two chloroplast genes indicate that A. alata is distinct from A. radiata and other palmate species in the genus. This presentation will explore the morphological distinctions of A. alata and its evolutionary relationships with other member of Adiantopsis.
