This species has long gone by the name Amphicarpum purshii which was based on Milium amphicarpon Pursh but the name A. amphicarpon has priority. When Kunth transferred M. amphicarpon to his new genus Amphicarpum he lists "Milium amphicarpum" as a synonym so it appears that Kunth was attempting to avoid the creation of the tautonym Amphicarpum amphicarpum when he created the substitute name A. purshii. Since the original spelling of the specific epithet is amphicarpon and not amphicarpum the correct name for this taxon is Amphicarpum amphicarpon and Kunth's A. purshii is superfluous and therefore illegitimate.
