Abstract

The morphology of the Purpureae Group of North AmericanAristida is assessed by principal components and statistical analyses. Long considered a complex of about eight species, a mosaic of intergrading phenetic forms is revealed and the complex is reduced to one species with seven varieties. The taxa that are recognized areAristida purpurea var.purpurea, var.nealleyi (comb. nov.), var.curvifolia (comb. nov.), var.parishii (comb. nov.), var.wrightii (comb. nov.), var.fendleriana, and var.longiseta. A key and synopses for the varieties are provided.
