Vachellia flava, synonym Acacia ehrenbergiana,[2] is a species of drought-resistant bush or small tree, commonly known as salam in Arabic.

[3][4] This shrub resembles the red acacia (Vachellia seyal) but that species lives in habitats with higher precipitation and has thorns that are shorter than its leaves.

[3] It is typically found growing in shallow depressions and gullies, positions where water can be expected to seep into the ground on the rare occasions when rain falls.

[3] It is an important fodder plant for camels, goats and sheep and the flowers are visited by bees which make "acacia honey" from the nectar.

[3] The timber is used for charcoal and firewood, the bark for fibre to be wound into ropes, and the sap produces a low quality gum which oozes from damaged parts of the trunk.
