Taxon distribution as listed in assessment
This species appears to have a scattered distribution in the UAE. Jongbloed et al. (2003) show records in the west (Sabkhat Matti), at Jebel Hafeet, and in the northwest, in the Musandam Peninsula. It has also been found in Taweelah, Umm al-Qaiwain, Ra's al-Khaimah and the Sweihan-Al Hayer area, and is possibly distributed along the entire near-coastal region west of Abu Dhabi Island (Brown et al. 2007). More recent surveys confirm that the species is abundant in deserts in the northern Gulf (G. Brown pers. comm. 2019). Globally, this species occurs in southern Africa, across much of northern Africa, Spain, France, the Middle East and various parts of Central Asia (Board of Trustees, RBG Kew 2018). It has been widely introduced to the Americas, parts of western Europe, and to Australia.

Habitat
Habitat details as listed in assessment
This species is an annual grass that grows up to 0.2 m in height, flowering from February to March. It grows in sand and silt between rocks (Jongbloed et al. (2003). MEW (2010) have the habitat as stable sand sheets often overlaying limestone. As a desert annual, it can be absent for many years and only appear, or are more conspicuous, in particularly wet seasons (Sakkir and Brown 2014).

Assessment rationale/justification
This species has a poorly known distribution in the UAE, from Sabkhat Matti in the west, possibly along near-coastal areas to Abu Dhabi Island, and from Taweelah to Ra's al-Khaimah, and from inland areas such as Jebel Hafeet and the Sweihan-Al Hayer area. Although the species is likely to have been impacted by, especially, coastal development, it is considered Least Concern.
