Discussion

Dalea albiflora is a complex and variable species that could use further morphological and cytological studies. While herbarium specimens cannot be sorted into varieties in any consistent way, in the field, delicate plants with slender, creeping rootstocks may grow with, and appear quite distinct from, plants with a stout caudex; such plants have been called D. ordiae. There are few chromosome counts available; preliminary study suggests that the former plants are tetraploid and the latter diploid (D. E. Ward et al. 1993).

Dalea ornata is nearly endemic to the Columbia-Snake river basin. In California, the species is known only from the Shaffer Mountain region in Lassen County.
