Discussion
Variety curtiflorus is known from Gilliam, Wasco, and Wheeler counties in north-central Oregon. D. D. Keck and A. Cronquist (1957) cited a specimen from Wheeler County (L. F. Henderson 5503, CAS) as probably this taxon, noting the flowers were immature. A duplicate specimen at MO clearly is var. curtiflorus, with corollas 15–18 mm and staminodes with one or two hairs near their tips. An anomalous specimen at MO (E. A. Purer 7811) collected in Yakima County, Washington, appears close to var. curtiflorus, with corollas 18–20 mm, staminodes sparsely lanate, and leaf margins dentate. This collection was made about 120 km north of the northernmost collections of the variety.
