Taxonomic Notes
This species is widely placed with the genus Emex, however, we follow Schuster et al. (2015) in retaining this species within Rumex.
Taxon distribution as listed in assessment
Widespread within the central desert of the UAE (Jongbloed et al. 2003). It has been recorded from a range of altitudes, up to c. 1,200 m (Feulner 2011). Also recorded in moist, disturbed grounds (MEW 2010). Its native range is Macaronesia, through the Mediterranean to the Arabian Peninsula (Board of Trustees, RBG Kew 2019).

Habitat
Habitat details as listed in assessment
It is found in sandy habitats including compacted sand, disturbed soils, wadis and the silt of plantations (Jongbloed et al. 2003, Norton et al. 2009). However, it is also recorded from agricultural areas (Perry 2008) and has been described as a weed in cultivated and abandoned fields (Feulner 2011). This annual herb species has a thick taproot, fleshy branches and rosette leaves (Ghazanfar and Fisher 1998, Jongbloed et al. 2003, Mahmoud et al. 2018). It can grow up to 30 cm in height, produces small green flowers between February to April in addition to both an above ground fruit and a below ground fruit (Jongbloed et al. 2003). It is a salt tolerant plant (Karim and Dakheel 2006) and is an important contributor to biomass in dune and stabilised sand environments (Ghazanfar and Fisher 1998).

Assessment rationale/justification
This species is widespread at lower altitudes in the UAE. Although data are lacking on the population size and trend, the species is assessed as Least Concern as it is thought unlikely that it will approach the thresholds for a threatened category.
