Taxon distribution as listed in assessment
In the UAE, the species has been recorded in wadi beds in the Wadi Wurayah National Park (G. Brown pers. comm. 2019) and a ravine on the slopes of Jebel Qitab in the UAE (Feulner 2016), in addition to being recorded once from Jebel Masafi (Jongbloed et al. 2003). These records are from a range of elevations (Feulner 2014). The species is likely to be present in all wadi areas south of the Ru'us al-Jibal (G.R. Feulner pers. comm. 2019), but has been overlooked. Globally, this species occurs in North Africa, southern Europe, the Middle East, Pakistan and India (Board of Trustees, RBG Kew 2018).

Habitat details as listed in assessment
This species appears to grow best in stony beds (Feulner 2016). It is an annual grass and is probably overlooked due to its similarity to Lolium species (Jongbloed et al. 2003).
