Heartwood is dark reddish brown. Sapwood is yellow. Uniform medium texture. So named for the seeds and pods that camels and giraffes (carefully) eat from this tree, despite its long thorns. Camelthorn was formerly placed in the Acacia genus (A. erioloba), but in the mid 2000s the massive genus was divided into five distinct genera (amid much debate), with most African species being reclassified into the Vachellia or Senegalia genera.
