The species is widespread in the Hajar Mountains, with additional records from Jebel Hafeet (e.g, Wadi Tarabat; Fawzi and Ksiksi 2012), Wadi Al Ain (Mousa and Fawzi 2009), and from several farmed areas in Wadi Ghalilah, northern Ra's al-Khaimah. The species was not found in Wadi Wurayah National Park (although no attempt was made to specifically differentiate from Sisumbrium erysimoides; Feulner 2011). The species was recorded for Wadi Helo (El-Keblawy 2011) but not recorded for that area by the later El-Keblawy et al. (2016). Sharjah Seedbank & Herbarium hold specimens from Wadi Helo (Fujairah), Al Ain (Abu Dhabi), and Wadi Al Nahw, Oman. The global range of this species is around much of the Mediterranean basin, north-east Africa, through the Arabian Peninsula to Pakistan and Central Asia (Board of Trustees, RBG Kew 2019). The species has been very widely introduced and naturalised.

This species is widespread through the Hajar Mountains in the eastern UAE, with additional records from Jebel Hafeet (Jongbloed et al. 2003), north to R'as al-Khaimah, where it is found on the alluvial plain (Western 1983). The species occurs within the 'Olive Highlands' of the southern Hajar Mountains (Feulner 2014), within Wadi Wurayah National Park (WWNP; Judas 2016), and occurs throughout the UAE part of the Ru'us al-Jibal to at least 1,600 m (Feulner 2011). The global range of this species is around much of the southern Mediterranean basin to the north-east and east of Africa, through the Arabian Peninsula to Iran and Pakistan (Board of Trustees, RBG Kew 2019). The species has been widely introduced and naturalised.

In the UAE, this species is relatively widespread in the Hajar Mountains (Jongbloed et al. 2003) and also occurs on Jebel Hafeet (Sakkir and Brown 2013). The species occurs in the southern Ru'us al-Jibal to c. 1,150 m (Feulner 2011). The species occurs in Wado Helo (El-Keblawy et al. 2016) and is known from the Wadi Wurayah National Park (WWNP) from a single specimen in Wadi Zikt (Feulner 2016). The global range of this species is from Spain, across northern Africa, and through the Arabian Peninsula (Board of Trustees, RBG Kew 2019).

In the UAE, this species is widespread in the Hajar Mountains and also occurs on Jebel Hafeet (RGBE Herbarium (<a href=""http://data.rbge.org.uk/herb/E00377490"">lower slopes, coll. R.A. Western, 1982</a>), Jongbloed et al. 2003, Fawzi and Ksiksi 2012). The species occurs rarely in the Ru'us al-Jibal to c. 600 m (Feulner 2011) and in the Wadi Wurayah National Park (WWNP; Feulner 2016). The global range of this species is from Israel and Palestine in the eastern Mediterranean and through the Arabian Peninsula (Board of Trustees, RBG Kew 2019).

Within the UAE, this species is widespread in the Hajar Mountains and Ru'us al-Jibal (Jongbloed et al. 2003, Feulner 2011), and also occurs on Jebel Hafeet (<a href=""http://data.rbge.org.uk/herb/E00377085"">RBGE Herbarium</a>; coll. J.N.B. Brown, west side of the mountain, 1983). The global range of this species is across northern Africa, the eastern Mediterranean, and through the Arabian Peninsula (Board of Trustees, RBG Kew 2019).

Within the UAE, this species is widespread in the Hajar Mountains and Ru'us al-Jibal (Jongbloed et al. 2003, Feulner 2011), and also occurs on Jebel Hafeet (RBGE Herbarium; coll. J.N.B. Brown, west side of the mountain, 1983). It has been recorded at altitudes up to 1,350 m (Jongbloed et al. 2003, Feulner 2011). The global range of this species is the eastern Mediterranean to the Arabian Peninsula to Iran (Board of Trustees, RBG Kew 2019).

Within the UAE, this species is widespread throughout sand desert (Jongbloed et al. 2003). Globally, the native range of this species spans from the eastern Mediterranean to the Arabian Peninsula (Board of Trustees, RBG Kew 2019).

This species is widespread within the north of the Hajar Mountains, south to the Al Munay'i area (Jongbloed et al. 2003, Sharjah Seedbank & Herbarium; S. Gairola pers. comm. 2019), in addition to the Ru'us al-Jibal (Jongbloed et al. 2003, Feulner 2011). Globally, this species ranges from the Canary Islands to the Mediterranean basin, northeast tropical Africa and east to Pakistan and Transcaucasus (Board of Trustees, RBG Kew 2019).

Within the UAE this species is widespread within the northern Hajar Mountain range and in the southern part of the Ru'us al-Jibal (Jongbloed et al. 2003). This plant has been recorded from elevations up to 1600 m in the Ru'us al-Jibal (Feulner 2011). Globally, the native range of this species spans from Spain, across northern Africa and on to the Arabian Peninsula and Pakistan (Board of Trustees, RBG Kew 2019).

The species is common and widespread in the Hajar Mountains and the Ru'us al-Jibal (MEW 2010) in the UAE. In the Ru'us al-Jibal, the species occurs to at least 1,500 m elevation (Feulner 2011). The species is present in Wadi Wurayah National Park (Feulner 2016) and in the 'Olive Highlands' in the southern parts of the Hajar Mountains in the UAE (Feulner 2014). The global range of this species is uncertain as it has been widely introduced and naturalised; it appears to to have a circum-Mediterranean native distribution, extending as a native to parts of western, central and eastern Europe (Marhold 2011), but considered an archeophytic introduction in the UK (BSBI/BRC 2017) and some other countries, and through the Arabian Peninsula (Board of Trustees, RBG Kew 2019). Introduced to South and East Asia, southern Africa, and the Americas.
