This is a common and widespread species in the Hajar Mountains (Jongbloed et al. 2003) and also is recorded south to Jebel Hafeet (Sakkir and Brown 2014). Al Meharibi et al. (2019) show presence of this throughout the east coast. The species is recorded from the Ru'us al-Jibal, although uncertain if from parts of the mountains within the UAE, and confusion is possible with other members of the genus (Feulner 2011). Feulner (2016) considers only this species of Cymbopogon to present in Wadi Wurayah. The native range of this species is in Africa from the Sahara and the Sahel to Kenya, east through the Arabian Peninsula to Iran (Board of Trustees, RBG Kew 2019).

This species was recorded in the Ru'us al-Jibal under the name, Cymbopogon jwarancuse (Jongbloed et al. 2003). It is thought to prefer high elevations (Patzelt 2015), having been recorded from the summit of Ra's Mintera, c. 1880 m asl, in the Ru'us al-Jibal (Feulner 2011). Globally, the native range of this species spans from Turkey to Socotra and on to China (Board of Trustees, RBG Kew 2019). Plants of the World Online lists the UAE as a native country of occurrence for this species (Board of Trustees, RBG Kew 2019).

This species is known from Jebel Ali (Jongbloed et al. 2003), in addition to Jebel Hafeet, Hamriyah, Sharjah, Ras al-Khaimah and Sila in the western UAE. It was also found from Wadi Siji in 2017. Crotalaria persica is known considered to have possibly been lost from Jebel Ali, in addition to subpopulations being lost due to development. In particular, a subpopulation was lost due to construction of a radio mast (G.R. Feulner pers. comm. 2019) and the occurrence in Taweela no longer exists (G. Brown pers. comm. 2019). The estimated EOO for this species is 10,500-15,000 km²and the number of threat-based locations is considered to be close to ten, according to the threat of development. Globally, this species is found from north-east tropical Africa to Pakistan (Board of Trustees, RBG Kew 2019).

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).
