Smith's and the chestnut-collared longspur were each other's closest relatives (sister taxa). [5] The Lapland longspur likely diverged from an ornatus/pictus ancestor near the beginning of the Pliocene (4.4–6.2 million years ago) and the snow and McKay's buntings diverged within the last 100,000–125,000 years.

Audubon named a species of bird as Smith's Lark-Bunting or Plectrophanes Smithii but this had already been described as Calcarius pictus by Swainson. The English name of Smith's longspur continues to be used. In 1848 he was reported to the Board of Medical Examiners for unprofessional conduct resulting in the end of his medical career. [2] [3]
