Morphologic and Taxonomic Study Based on Wild Selected Plant Species Belonged to Genus <i>Acacia</i>—Al Baha Region (Saudi Arabia)

Abstract

This work is a taxonomic study on the genus Acacia in the Tehama area, Al Baha region—Saudi Arabia. It depended on a brief description of the Climate, Topography, and Geology of the study area. The total numbers of species identified were seven species, classified into two major groups depending on their differences in the vegetative, floral, and fruit characteristics. Scientific classification of the genus Acacia was provided. Botanical description and distribution of species on habitats were determined for all seven species. Medicinal properties and local uses for some species were obtained. All identified species have been illustrated by photos of their habitats. A taxonomic key was constructed to show the differences among the seven wild selected species. Botanical names and synonyms were updated and vernacular names have been presented.
