Species
Taxon distribution as listed in assessment
This species has been recorded in inland areas of the UAE (Shwayb and Al Ain) (Jongbloed et al. 2003, El-Keblawy 2012). A single specimen is held by RBGE Herbarium, <a href=""http://data.rbge.org.uk/herb/E00357808"">collected from near Shwayb</a>. The EOO is estimated at between 4,500 and 5,500 km<sup>2</sup>, however, the AOO cannot be estimated as detailed locality data are not available. The species is found across North Africa, from the western Sahara to northeast Africa, through the Arabian Peninsula, to southern Iran (Board of Trustees, RBG Kew 2019).

Habitat
Habitat details as listed in assessment
This is an annual species, recorded from inland sand areas and dunes in the UAE (Brown and Sakkir 2004), that grows up to 0.2-0.35 m (Jongbloed et al. 2003). MEW (2010) also reported the species from cultivated fields. Elsewhere in its range, it is also found in coastal dunes (Quattrocchi 2006).

Assessment rationale/justification
This species has been recorded from inland areas of the UAE in the areas around Shwayb and Al Ain. The distribution does not appear well known, and it may occur more widely in suitable habitat. Grazing by livestock and camels may impact the species, and its habitat is subject to conversion, especially urbanisation. The extent of occurrence (EOO) is restricted, estimated at between 4,500 and 5,500 km<sup>2</sup>, however, the species occurs in many more than ten locations, and it is suspected that any population decline is not approaching that required for a threatened category. As a result, the species is assessed as Least Concern, but the species should be reassessed if further data become available.

Threats listed in assessment
Grazing by livestock and camels may impact the species, but there is no information on the impact of this. MEW (2010) considered its habitat to be subject to change (presumably conversion to agriculture) and urbanisation.
