Taxonomy
Vachellia planifrons was scientifically described in 1834 by Robert Wight and George Arnott Walker Arnott and named Acacia planifrons.[1] Prior to its first valid description Mimosa eburnea was described in 1805,[1] but this name had already been used in 1782.[5] In 2014 it was moved to Vachellia by Subramanyam Ragupathy, David Stanley Seigler, John Edwin Ebinger, and Bruce Maslin. It has no accepted subspecies and six synonyms.[1]
