1. Erysimum

Erysimum is one of the largest genera of the Brassicaceae (Cruciferae) . It is well known for its taxonomic complexity due to tremendously overlapping morphological characters, and its diversity estimations range from 150 ( Zhou et al. 2001, Al-Shehbaz 2010) to 290–350 species ( Polatschek & Snogerup 2002). The diversity of Erysimum is centered in SW Asia and Eastern Mediterranean where new species are still being described (e. g., Polatschek 2008, 2011; Moazzeni et al., 2014).

According to the Flora Iranica account ( Polatschek & Rechinger 1968) and subsequent additions ( Polatschek 2008, 2010, 2011; German 2014), 31 Erysimum species occur in Iran. One more species described herein was discovered during the botanical investigation of Hezar (Hezar-Lalezar) mountains which formerly had been rarely studied by botanists. Taking this novelty into account, 32 Erysimum species are recorded at the moment from Iran, seven of which are endemics.
