Abstract
Taxonomy and distribution of the poorly known Erysimum
vassilczenkoi (Syrenia macrocarpa) (Brassicaceae)
is revised on the basis of herbarium material and field studies. The
presence of the species in the flora of Mongolia is not confirmed;
instead, a new species, E. mongolicum, is
described from the Mongolian Altai, and E. kotuchovii
is reported for Mongolia for the first time. The distinguishing
characters and relationships of the three species are discussed. A map
of their distribution and a key to their identification also including
the closely related E. siliculosum are given. Some
comments on the status of Syrenia are added.
