Delphinium hansenii
Delphinium sapellonis
Subspecies 3 (3 in the flora).
Although Delphinium hansenii has often been confused with D. hesperium, seeds will instantly allow identification. Seeds of Delphinium hansenii are, as far as known, unique, bearing numerous, elongate, prismlike raised structures (extensions of single cells or small groups of cells) over the entire seed coat. If seeds are absent, larger flowers, more open inflorescences (except in D. hesperium subsp. cuyamacae), and general absence of pubescence of long hairs in D. hesperium are apparent upon comparison of the two species. Separating D. hansenii from D. variegatum may also be difficult. Again, seeds leave no doubt. In addition, smaller flowers and greater number of flowers per plant of D. hansenii should serve to distinguish D. hansenii from D. variegatum. White-flowered D. hansenii has been confused with D. gypsophilum and with D. hesperium subsp. pallescens. Other than seeds, pubescence of long hairs and smaller flowers present in D. hansenii and absent in the others will distinguish them.

Delphinium sapellonis hybridizes with D. barbeyi and D. robustum. It replaces D. robustum and represents the southern Cordilleran complex at higher elevations of the southern Sangre de Cristo Mountains east of Santa Fe. It is not known elsewhere.

1. Sepals dark blue-purple to white. | → 2 |
2. Leaves primarily basal (although leaves may be dry at anthesis and thus lost in herbarium specimens, petiole base will be present); cauline leaves usually fewer than 3; sepals bright blue to white. | subsp. kernense |
2. Leaves primarily cauline, basal leaves usually absent at anthesis; cauline leaves 3 or more; sepals dark blue-purple to white or pink. | subsp. hansenii |
