Within the UAE, it is described as occurring along the Arabian Gulf coastline (Brown et al. 2007). Jongbloed et al. (2003) shows a wide distribution from gravel plains west of the Hajar Mountains, south and west into Dubai Emirate. Globally, the native range of this species encompasses temperate Asia and the Arabian Peninsula (Board of Trustees, RBG Kew 2019).

Within the UAE, it is known to occur in the Hajar Mountain range and in the south of the Ru'us al-Jibal (Jongbloed et al. 2003). In the Ru'us al-Jibal it is recorded at elevations of up to 1600 m (G.R. Feulner, in litt, MEW 2010, Feulner 2011), while in the Hajar Mountains it is found at lower altitudes (MEW 2010). Globally, the native range of this species encompasses the Mediterranean, northern Africa and the Arabian Peninsula (Board of Trustees, RBG Kew 2019).

Within the UAE, this species is known from the Liwa region and towards the far west of the country, along the Arabian Gulf coast (Jongbloed et al. 2003). This species is native to Egypt, the Arabian Peninsula and through to Afghanistan (Board of Trustees, RBG Kew 2019).

Within the UAE, this species is widespread throughout sandy and coastal areas in the north of the country and down to Al Ain (Jongbloed et al. 2003). It is also thought to occur on some islands within the UAE (MEW 2010). Globally, the native range of this species spans from northern Africa and the Sahara to the Arabian Peninsula (Board of Trustees, RBG Kew 2019).

Within the UAE, this species is thought to occur along a specific stretch of the Arabian Gulf Coast, between Abu Dhabi island and Ras al-Khaimah (Brown et al. 2007). It was also recently reported from Jebel Hafeet (Sakkir and Brown 2014) and is considered to grow within the non-saline coralline sands which stretch northeast of Taweela and into the Ras al-Khaimah (G. Brown pers. comm. 2019). Globally, the native range of this species spans from northern Africa to the Arabian Peninsula (Board of Trustees, RBG Kew 2019).

Within the UAE, this species occurs along the western slopes of the Hajar Mountains from Shawka, south to the border with Oman (Jongbloed et al. 2003, Feulner 2011). The species also occurs on Jebel Hafeet (Perry 2008) on the northern summit wadi on Jebel Hafeet (at almost 1,000 m asl; G.R. Feulner, in lit. MEW 2010), where it persists (S. Sakkir and G. Brown pers. comm. 2018). According to G.R. Feulner (in lit. MEW 2010), this species ""is consistently present as one or a few clumps/groves in almost every wadi from Shawka south [to the Oman border], normally at places where the wadi broadens for one reason or another and silt accumulates. It is relatively common in the wadis in the greater Juwaif area, about half-way between the Hatta Road and Mahdhah."" The Sharjah Seedbank & Herbarium (SSBH) recorded the species from the Al Dhaid-Masafi road (Thaoban), and found four new clumps of the plant in Al-Bardy and Al-Wishah (in gravelly area east of Dhaid); these clumps are located inside farms, and local people reported that ""...they planted it"" a long time ago (T. Mahmoud pers. comm. 2019). The EOO is estimated at between 1,500 and 2,000 km², whilst the AOO is less than 500 km²and is likely to be as little as 300 km². The species also occurs in adjacent areas of Oman (G.R. Feulner in lit. MEW 2010). Globally, the species is native from the southern Arabian Peninsula to Iran and Pakistan (Board of Trustees, RGB Kew 2018).

In the UAE, this species is distributed along the north-eastern coast (Jongbloed et al. 2003, Al Mehairbi et al. 2019), probably including the Wadi Wurayah National Park (Feulner 2016), as well as Al Ain and just south of the Dubai-Abu Dhabi border near the coast (Jongbloed et al. 2003). It has also recently been recorded from Jebel Hafeet (Sakkir and Brown 2014). Al Mehairbi et al. (2019) also record the species from the Ru's al-Jibal, although the species is absent from Feulner (2011). Globally this species occurs in the north and east Africa, the Arabian Peninsula, Iran, Pakistan, India and Thailand (Board of Trustees, RBG Kew 2018).

This species is widespread across northern parts of the UAE (Jongbloed et al. 2003). It is known from the Ru'us al-Jibal (Feulner 2011) and in Wadi Wurayah National Park (Feulner 2016). G.R. Feulner (in lit., MEW 2010) comments that this species is difficult to distinguish in the wild and that it has been widely cultivated as a landscape plant. Al Mehairbi et al. (2019) show it to be absent from parts of the western coast of Abu Dhabi Emirate. Globally, this species occurs in North and East Africa, the Arabian Peninsula, Central Asia, India and Thailand (Board of Trustees, RBG Kew 2018).

This species seems to be recently recorded for the UAE and appears to be scattered and widespread throughout the country. Sakkir et al. (2017) note that the species is known from offshore islands in Abu Dhabi Emirate, but without details. Mahmoud et al. (2018) recorded the species from eastern parts of the UAE, again without locality details. The native range of this species spans from north-east tropical Africa, through the Arabian Peninsula, to southern Iran and south-central China, Southeast Asia, and Japan (Board of Trustees, RBG Kew 2019).

Within the UAE, it is known to be widespread across the Hajar Mountains and within the Ru'us al-Jibal (Jongbloed et al. 2003). It seems to grow between low to medium elevations and has been recorded up to 1250 m in the Ru'us al-Jibal (Feulner 2011). Globally, this species is native to the Gulf States and Oman (Board of Trustees, RBG Kew 2019).
