    • Remarks
      Identifying the different species of Vachellia is often challenging in the field, as morphological characteristic used for identification can be variable between individuals, not always visible, and the species may be confused—especially since AlUla County lies in a contact zone where the ranges of several species overlap. Habitat characteristics and field experience can help identification, but these taxa remain difficult to distinguish (one single local species name can refer to several species).
