ABSTRACT

Sometimes interpreted as subspecies P. marítima L. subsp. ciliata Printz [Veg. Sib.- Mong. Front, 1921: 397], P. marítima subsp. salsa (Pallas) Sojak [Preslia, 1962, 34, 4: 414]. However, morphological characteristics (leaf with spines on margin and generally beneath and generally more or less ciliate lobes of corolla) and difference in the distribution range, according to this author, suggest treating the Siberian plants as a species.
