Anacardium, the cashews, are a genus of flowering plants in the family Anacardiaceae, native to tropical regions of the Americas. The best known species is Anacardium occidentale, which is commercially cultivated for its cashew nuts and cashew apples.
Etymology
The name Anacardium, originally from the Greek, actually refers to the nut, core or heart of the fruit, which is outwardly located (ana means "upwards" and -cardium means "heart").
Taxonomy
The oldest species of the genus Anacardium is Anacardium germanicum from the Eocene aged Messel Pit of Germany, well outside the current range of the genus.{{Cite journal |last1=Manchester |first1=Steven R. |last2=Wilde |first2=Volker |last3=Collinson |first3=Margaret E. |date=October 2007 |title=Fossil Cashew Nuts from the Eocene of Europe: Biogeographic Links between Africa and South America |url=http://www.journals.uchicago.edu/doi/10.1086/520728 |journal=International Journal of Plant Sciences |language=en |volume=168 |issue=8 |pages=1199–1206 |doi=10.1086/520728 |s2cid=84629334 |issn=1058-5893}} They were present in the Americas by the Oligocene-Miocene, as evidenced by the species Anacardium gassonii from Panama.{{Cite journal |last1=Rodríguez-Reyes |first1=Oris |last2=Estrada-Ruiz |first2=Emilio |last3=Monje Dussán |first3=Camila |last4=de Andrade Brito |first4=Lilian |last5=Terrazas |first5=Teresa |date=2021-06-02 |editor-last=Vermeij |editor-first=Geerat J. |title=A new Oligocene-Miocene tree from Panama and historical Anacardium migration patterns |journal=PLOS ONE |language=en |volume=16 |issue=6 |pages=e0250721 |doi=10.1371/journal.pone.0250721 |issn=1932-6203 |pmc=8171895 |pmid=34077439|bibcode=2021PLoSO..1650721R |doi-access=free }}
