Discussion
In the field, Delphinium bicolor subsp. calcicola is readily separated from D. bicolor subsp. bicolor on the basis of its brighter colored, slightly larger flowers and its edaphic preference. Delphinium bicolor subsp. calcicola usually flowers somewhat later where the two are sympatric. These differences are often not apparent from herbarium specimens. Specimens of this taxon misidentified as D. geyeri account for most reports of that species from Montana.
