Assessment rationale/justification
This species is found across the UAE in scattered localities. Although it is generally described as not common, it is thought to be overlooked and therefore more common than initially thought. In addition, it is known to occur in at least one protected area within the UAE. However, it is currently assessed as Data Deficient because the origin in the UAE of this globally introduced ruderal weed requires confirmation.

Taxon distribution as listed in assessment
This halophytic species is found in scattered locations throughout the UAE (Jongbloed et al. 2003). The origin of the species in the UAE requires confirmation; whilst GRIN (2019) considers it to be native to the UAE, others consider (Anum et al. 2018, Xu 2019) it to be native to Africa. The global distribution of this species is from Africa to Israel and the Arabian Peninsula, and from Pakistan to India (Board of Trustees, RBG Kew 2019). Globally, it is a widespread introduced ruderal invasive weed of crops and cultivated areas.
