Discussion

Variety rickardii was once thought to be confined to the Hanford Atomic Energy Site, Benton County, Washington, but has more recently been documented in Wasco County, Oregon. Although plants of var. rickardii contrast in features relative to other members of the complex, it appears to be most closely related to var. conjunctus despite its strigulose fruits, shorter fruiting pedicels, and smaller floral parts.
