Poljakov (Fl. URSS 26: 596-597. 1961) recognized two further varieties of Artemisia sublessingiana: var. gorjaevii, with slender erect stems usually 20-30 cm tall and short narrowly linear leaf lobes, and var. polysthicha, with lower stem leaves not more than 2 cm and often 3 stigmatic lobes.

"Artemisia maritima Linnaeus [var.] sublessingiana" (Keller, Bot.-Geogr. Issledov. Zaisansk. Semipalatinsk. Obl. 2: 89. 1912) belongs here but is a nomen nudum and was therefore not validly published (Vienna Code, Art. 32.1(d)).
