Arabidopsis lyrata consists of several closely related species or subspecies. The number of units historically recognised has varied and the most recent taxonomic revision (Al-Shehbaz & O’Kane 2002) recognises one species and three subspecies:

  • A. lyrata ssp. lyrata (North America)
  • A. lyrata ssp. kamchatica (North America, Kamchatica (Russia), Japan, Taiwan)
  • A. lyrata ssp. petraea (Europe, Siberia)

A detailed taxonomic account is provided in Al-Shehbaz & O’Kane 2002, including a full list of synonyms.
