Abstract

Populations of Adiantum growing on serpentine barrens in Pennsylvania and Maryland have been identified as A. aleuticum (Rupr.) C.A.Paris ( = A. pedatum L. var. aleuticum Rupr.). This species, and the allopolyploid A. viridimontanum C.A.Paris, are known from serpentine in New England and Canada. A phylogenetic analysis based on two plastid markers showed that the Pennsylvania and Maryland populations are A. pedatum sensu stricto rather than A. aleuticum or A. viridimontanum.
