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).
