Assessment rationale/justification
Previously known only from a record by A.R. Western, the species was recently refound at a single site in Fujairah Emirate (D. Aplin pers. comm. 2020). Although the area of occupancy (4 km<sup>2</sup>) is restricted and it occurs at a single location based on potential threats, data are lacking on habitat, distribution (AOO and EOO), and the population size and trends, and the species is considered Data Deficient Research is required to confirm the distribution of the species in the UAE, including review of the western locality, and conservation actions are required.

Taxon distribution as listed in assessment
Within the UAE, this species was considered to be known only from a record by A.R. Western, as the synonym Indigofera leptocarpa Hochst. & Steud. ex Balf.f., cited in Jongbloed et al. (2003; it was presumed that this record was based on Western (1989), however the species is not listed in that book). The locality of the record(s) is not known. The species was recently rediscovered at a single site in Fujairah Emirate (i.d. confirmation, B. Schrire and G.P. Lewis); a small population found on a hill on the western edge of Fujairah city (D. Aplin pers. comm. 2020). Globally, the native range of this species include the Sahara and northern Africa, in addition to Namibia, South Africa, Sudan, Socotra, and the Arabian Peninsula (Board of Trustees, RBG Kew 2019). Records in the Arabian Peninsula include Oman, Yemen, and KSA.
