Taxonomy

In 1853 Eriogonum alatum was scientifically described and named by John Torrey, placing it in the Eriogonum genus. Hugo Gross proposed moving it to Pterogonum in 1913, but this has not become the accepted classification. Together with its genus it is part of the Polygonaceae family and the species has two accepted varieties.[2]

  • Eriogonum alatum var. alatum – Widespread from Wyoming to Chihuahua[4]
  • Eriogonum alatum var. glabriusculum – Native to New Mexico, Texas, and Oklahoma[5]

Eriogonum alatum has eight synonyms, two of the species and six of variety alatum.[3]
