Balanites aegyptiaca
"Balanites aegyptiaca" has been cultivated in Egypt for more than 4000 years, and stones placed in tombs as votive offerings have been found as far back as the Twelfth Dynasty. The tree was described in 1592 by Prospero Alpini under the name 'agihalid'. Linnaeus regarded it as a species of "Ximenia", but Michel Adanson proposed the new genus of "Agialid". The genus "Balanites" was founded in 1813 by Delile.
