Assessment rationale/justification
This species is widespread in the Hajar Mountains in the eastern UAE, where it generally occurs at higher altitudes. The identity of the species present in the UAE requires confirmation, and the draft Red Data Book for Plants (MEW 2010) notes that the photograph presented for Trichodesma enetotrichum in Jongbloed et al. (2003) actually shows T. africanum. The species is assessed as Data Deficient.
