Assessment rationale/justification
Confirmation of the distribution and population status of this species in the UAE is needed. The species is found along the northern Gulf coast (MEW 2010), but without specific localities, from the east coast (RGBE Herbarium; Khor Fakkan and Kalba), and from Shwayb (RGBE Herbarium). The species is assessed as Least Concern. The species seems to be associated with anthropogenic habitats (plantations, gardens, by roadsides etc.), but perhaps just favours distributed areas.

Taxon distribution as listed in assessment
The species is found along the northern Gulf coast; in plantations, gardens, and by roadsides (MEW 2010). RBG Edinburgh Herbarium holds specimens from; 1. <a href=""http://data.rbge.org.uk/herb/E00358081"">Khor Fakkan</a> (Fujairah) in sandy soil, c. 1 km from coast; 2. <a href=""http://data.rbge.org.uk/herb/E00358082"">3 km north of Shwayb</a>, in fixed dunes, and 3. <a href=""http://data.rbge.org.uk/herb/E00358092"">Kalba date gardens</a>, 1 km west of Kalba, in a shallow archaeological pit in sandy soil within a former agricultural field. Feulner (2011) did not record the species from UAE parts of the Ru'us al-Jibal. The species has a wide native distribution, from much of Africa, through the Arabian Peninsula to Pakistan, and from China (Board of Trustees, RBG Kew 2019). It has been very widely introduced throughout the Americas. It is considered introduced and naturalised in Taiwan (Jung and Cheng 2016), and the origin of the species in mainland China perhaps requires confirmation.
