Within the UAE, this species was known from the southern Hajar Mountains and from near Al Ain (Jongbloed et al. 2003, G.R. Feulner in litt. MEW 2010), in addition to Jebel Hafeet (Fawzi and Ksiksi 2012), although it appears that many of these literature locality records occur in Oman rather than in the UAE (G.R. Feulner in litt. MEW 2010); in support of this, most of the localities shown in Jongbloed et al. (2003) for the species occur within Oman rather than the UAE). EAD (S. Sakkir pers. comm. 2019) hold records from several areas on Jebel Hafeet, including Wadi Tarabat. However, the species appears to be expanding its range northwards, perhaps partly due to its apparent ability to colonise silt behind dams (G.R. Feulner pers. comm. 2019). In recent years it has been confirmed from the outskirts of Fujairah city (G.R. Feulner pers. comm. 2019), from southeast of Shawka, just off the Sharjah-Kalba Road (D. Aplin pers. comm. 2019, i.d. G.R. Feulner) and from Wadi Shawka, Wadi Ham, Al-Qowr, Al Munay, Hatta and Masfut (Sharjah Seedbank & Herbarium; S. Gairola pers. comm. 2019). Globally, this species occurs from the Sahara to Kenya and on to the Arabian Peninsula (Board of Trustees, RBG Kew 2019).

Within the UAE, it has been recorded from the Wadi Wurayah National Park, the Hajar Mountains and Jebel Hafeet (Stuart and Stuart 1998, Jongbloed et al. 2003, Judas 2016).

Within the UAE, it has been recorded from both Al Ain and Abu Dhabi (Jongbloed et al. 2003). Globally, the native range of this species includes northern Africa, Macaronesia, the Mediterranean and through to Iran, according to Plants of the World online (Board of Trustees, RBG Kew 2019). GRIN (2019) exclude the Arabian Peninsula from the natural range of this species. G.R. Feulner (in litt., MEW 2010) suggests that the species may be a recent introduction to the UAE.

Within the UAE, this species occurs in the north of the country (Jongbloed et al. 2003). It is also known to occur in the Ru'us al-Jibal (Feulner 2011). Globally, this species' native range spans across both the Tropics and the Subtropics (Board of Trustees, RBG Kew 2019).

Within the UAE, it is known to occur in sandy coastal areas from Ajman to Ras al Khaimah (Weston 1983) and in Dubai (Jongbloed et al. 2003). Globally, the native range of this species spans from Macaronesia and Mauritania, across northern Africa to the Arabian Peninsula, Turkey and Iran (Board of Trustees, RBG Kew 2019).

Within the UAE, it is considered to be widespread in coastal areas along the Arabian Gulf (Jongbloed et al. 2003, Brown et al. 2007). Globally, this species occurs from northern Africa and the Mediterranean to the Arabian Peninsula and Iran (Board of Trustees, RBG Kew 2019).

Within the UAE, this species is known to be widespread throughout the north of the country (MEW 2010). It has also been recorded from offshore islands of the UAE (Jongbloed et al. 2003, Sakkir et al. 2017). Globally, the native range of this species encompasses Africa, the eastern Mediterranean, the Arabian Peninsula and Pakistan (Board of Trustees, RBG Kew 2019).

This species occurs along the eastern coast of the UAE (Jongbloed et al. 2003, MEW 2010). The estimated EOO for this species is 887 km². Globally, this species occurs from western tropical Africa to the Arabian Peninsula and the Indian subcontinent (Board of Trustees, RBG Kew 2019).

Within the UAE, this species occurs in Ras al-Khaimah, within Wadi Sal, Hatta and Masafi (UAE National Red List Workshop, 15th-19th September 2019, Dubai). Globally, this species occurs from the Sahara to Pakistan (Board of Trustees, RBG Kew 2019).

Within the UAE, this species has been recorded from the Ru'us al-Jibal (Jongbloed et al. 2003), at altitudes between c. 700 m and c. 1,400 m (Feulner 2011). Globally, this species is known to occur from the Mediterranean to Iran and the Arabian Peninsula (Board of Trustees, RBG Kew 2019).
