671003-04 The Erysimum strictum aggregate E. marschallianum, E. strictum
Geography: European - Asian.
Notes: Petrovsky: Asian records should be transferred to Erysimum marschallianum.
Elven: Erysimum marschallianum is suggested to be diploid (see below), whereas European E. strictum is counted as tetraploid and Asian and North American E. strictum as hexaploid. Diploids, tetraploids, and hexaploids are very similar and may belong within one polymorphic species.
