Assessment rationale/justification
This species occurs in the Wadi Wurayah National Park and across the northeast of the UAE. It is considered to be common and widespread within the UAE and, although it may be threatened by grazing, it is unclear what effect this currently has on the species. Therefore, this species is assessed as Least Concern.

Habitat details as listed in assessment
This perennial shrub species is found growing in gravel plains and sand dunes (El Aqamy 2004, Fawzi and Ksiksi 2012, Mahmoud et al. 2018). Within the Wadi Wurayah National Park, it is generally found growing on gentle wadi banks (Feulner 2016). The plant grows to between 90-100 cm in height and flowers between February and April (Jongbloed et al. 2003, Karim and Dakheel 2006). It is a moderately salt-tolerant species (Karim and Dakheel 2006). Crotalaria aegyptiaca is a crop wild relative of sunhemp, Crotalaria juncea (Kameswara Rao 2010).
Threats and conservation measures listed
Threats listed in assessment
Camels are able to graze on this species, meaning that this could pose a threat within this species' distribution (Karim and Dakheel 2006). However, it is not known to what extent this threat may impact the species.
