Taxonomy

The species was first described by William Jackson Hooker in 1838 as Douglasia arctica.[3] Molecular phylogenetic studies showed that the genus Douglasia is nested within Androsace.[4][5] The name "Androsace artica" was published in 1826 for a different species (now regarded as a synonym of Androsace ochotensis), so the replacement name Androsace americana, published by Per Wendelbo in 1961,[6] is used instead.
