Abstract

Astragalus mokiacensis has been a problematic species since it was first described in 1877. Every major revision delimited this taxon differently. A principal components analysis of morphological data from herbarium specimens was used to determine the affinities between type specimens and extant populations ofA. mokiacensis. The taxon recently recognized asA. lentiginosus var.trumbullensis is morphologically similar to the lectotype ofAstragalus mokiacensis. Astragalus lentiginosus var.trumbullensis is herein recognized as a lowelevation minor variant and considered a synonym ofA. mokiacensis. A taxonomic key and complete synonymy are included.
