OCHRADENUS ARABICUS (RESEDACEAE), A NEW RECORD FOR THE FLORA OF IRAN

The study of herbarium specimens of family Resedaceae from Iran (IRAN herbarium) resulted in the finding of a new species for the flora of Iran, Ochradenus arabicus. The specimens were collected in Chabahar (Sistan and Baluchestan province), in the SE part of the country. This new record constitutes an interesting disjunction for the range of this species, which was previously considered an endemic from the Arabian Peninsula. A brief description of this species and identification keys of the taxa of genus Ochradenus in Iran are provided, together with comments about their taxonomy and distribution.
