Species
Taxon distribution as listed in assessment
The species is widespread within the Hajar Mountains (Jongbloed et al. 2003) at elevations up to c. 1100 m (Feulner 2011). It has also been recorded on off-shore islands of Abu Dhabi (Sakkir et al. 2017). Its native range is from western Africa through the Arabian Peninsula to India (Board of Trustees, RBG Kew 2019).

Habitat
Habitat details as listed in assessment
It generally inhabits gravel plains and wadis (Jongbloed et al. 2003), but has also been reported from abandoned fields (Western 1991). Euphorbia granulata is also considered a weed in urban areas (Norton et al. 2009). However, it seems to thrive in montane habitats (G.R. Feulner, in litt, MEW 2010). An annual herb species, it produces white, solitary flowers which are present from February to June, in addition to a three-lobed fruit (Jongbloed et al. 2003, Mahmoud et al. 2018).

Assessment rationale/justification
This species is widespread at lower altitudes and montane habitats within the UAE. In addition, it is known to occur on offshore islands which is likely to cause its distribution to exceed the thresholds for threatened categories. Although data are lacking on the population size, the trend is inferred to be stable and therefore the species is assessed as Least Concern. Confirmation of the species' origin within the UAE (i.e. native or introduced) would be beneficial, as it has been known to be introduced to nearby countries.
