Species
Taxon distribution as listed in assessment
The species is mentioned by Jongbloed et al. (2003) without details. The species has been recorded from Jebel Hafeet (Sakkir and Brown 2014) and from Fujairah (RBG Edinburgh Herbarium; Jebal Ruwaydah at the head of Wadi Sidakh). More recent surveys confirm that the species is abundant in deserts in the northern Gulf (G. Brown pers. comm. 2019). The native range of this species is along Mediterranean coastal countries of North Africa to Ethiopia, and the eastern Mediterranean (from Greece eastwards), through the Arabian Peninsula, to Mongolia (Board of Trustees, RBG Kew 2019). The species has become widespread and invasive in arid and semi-arid regions of North America and Australia (CABI 2019).

Habitat
Habitat details as listed in assessment
This is a small, tufted annual grass that grows up to 0.2 m in height (CABI 2019). 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). MEW (2010) recorded the habitat as dry wadi banks and beds, whilst the RBG Edinburgh record was from a north-facing limestone hillside.

Assessment rationale/justification
The distribution of this species in the UAE is apparently not well documented, possibly as a result of confusion with Schismus barbatus, and it appears to be known from a very small number of records in the Hajar Mountains and Jebel Hafeet. This almost certainly does not represent its full range in the UAE, and recent surveys confirm that the species is abundant in deserts in the northern Gulf (G. Brown pers. comm. 2019). It is considered Data Deficient pending further information on its distribution.
