Varieties 2 (2 in the flora).

The varieties of Dalea pogonathera are geographically mostly separated with a broad transitional zone where intermediate individuals occur. Variety pogonathera is the more westerly distributed and upland form; var. walkerae has a more easterly range and occurs in more lowland situations. The region of intermediacy occurs in the Rio Grande valley from roughly Val Verde County to Zapata County.
