This species is recorded from the plains at the foot of Jebel Hafeet and along the east coast of the UAE (Jongbloed et al. 2003). This species tends to occur at lower altitudes and on gentler slopes (Ghazanfar and Fisher 1998, Feulner 2011). The estimated EOO is 7,369 km², however the AOO and the current number of locations is unknown. Its native range is from Macaronesia to India (Board of Trustees, RBG Kew 2019).

Within the UAE, this species only been recorded from Wadi Siji, in the northeast of the country (Jongbloed et al. 2003). Globally, this species occurs from central and north-east Africa, to the Arabian Peninsula, Iran and India (Board of Trustees, RBG Kew 2019).

In the UAE, the species occurs in the Hajar Mountains and east of Al Ain (Jongbloed et al. 2003). It has been recorded from Wadi Wurayah National Park (Judas 2016) and the park buffer zone (upper Wadi Ghulayyil Khun; Feulner 2016), Wadi Tarabat on Jebel Hafeet (Fawzi and Ksiksi 2012) and from the ""Olive Highlands"", although much less common there than at lower elevations in the mountains (Feulner 2014). MEW (2010) also reports the species from coastal wadis. The global range of this species is the eastern Arabian Peninsula to Iran and Pakistan (Board of Trustees, RBG Kew 2019).

This species appears to be known from a small number of isolated records in eastern Abu Dhabi Emirate (Jongbloed et al. 2003), including records from Al Ain city and from northwest of Abu Dhabi city (Sharjah Seedbank & Herbarium) and from Wadi Al Ain (Mousa and Fawzi 2009). Mahmoud et al. (2018) reported this species from gravel plains below the western slopes of the Hajar Mountains, but without specific localities. The draft Red Data Book for the UAE (MEW 2010) excluded this species on the basis that no confirmed specimens had been seen. Convolvulus pilosellifolius is easily confused with C. prostratus in the Arabian Peninsula (Wood et al. 2015) which may impact the known distribution of this species. The native range of this species is from eastern parts of North Africa, the eastern Mediterranean to Central Asia and Pakistan (Board of Trustees, RBG Kew 2019).

Within the UAE, this species is considered to be widespread within the Hajar Mountains (Jongbloed et al. 2003). Globally, the native range of this species spans across the Sahara, through to the Arabian Peninsula and on to India (Board of Trustees, RBG Kew 2019).

It is widespread throughout the northern UAE (Jongbloed et al. 2003). The native range of this species spans from Cape Verde to India (Board of Trustees, RBG Kew 2019).

This species is found in coastal areas and inland low dunes from Abu Dhabi northward to Ras al Khaimah (Jongbloed et al. 2003). Herbarium records (Sharjah Seedbank & Herbarium) indicate a more inland distribution in the northern Emirates, but these records might be the result of anthropogenic transport along road networks. The native range is through the Arabian Peninsula, to Iraq, Iran, and Pakistan (Board of Trustees, RBG Kew 2019).

Feulner (2014) reported this species from the ridgetops, ravines, cliffs and slopes in the Olive Highlands in the Hajar Mountains, and from the Ru'us al-Jibal (Feulner 2011). The species is found at higher altitudes from c. 650 m to c.1,880 asl (Feulner 2011, 2016; D. Aplin pers. comm. 2019). The native global distribution of this species is from the Arabian Peninsula to Iran and Pakistan (Board of Trustees, RBG Kew 2019).

Within the UAE, this species has been recorded from north of Masafi (A.R. Western, in Jongbloed et al. 2003; G.R. Feulner pers. comm. 2019). MEW (2010) considered it to occur in the foothills of the mountains. D. Aplin recently found the species in a narrow, steep-sided, north-facing wadi in metamorphic rocks c.1 km north of Al Khulaybiyah, north of Masafi, in the Emirate of Fujairah (D. Aplin pers. comm. 2019). Further investigations would be needed to determine if this is an isolated population. Globally, this species is native from Eastern Africa (Somalia), through the eastern Arabian Peninsula, to Iran, Pakistan and India (Board of Trustees, RBG Kew 2019).

Within the UAE this species has been recorded as a weed species from traditional agricultural plantations on the Gulf of Oman coast, both at the coast (Mirbah) and within the mountains (Wadi Safad) (G.R. Feulner pers. comm. 2019). It is also considered to grow at foothills of mountains (MEW 2010). Globally, this species is native to Socotra, Sinai, the Arabian Peninsula, Pakistan and India (Board of Trustees, RBG Kew 2019).
