ex Kunth[1] Anacardium, the cashews, are a genus of flowering plants in the family Anacardiaceae, native to tropical regions of the Americas.

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").

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.

[2] They were present in the Americas by the Oligocene-Miocene, as evidenced by the species Anacardium gassonii from Panama.

[3] As of July 2020[update], the PoWO (Plants of the World Online) accepts 13 species:[4] Data related to Anacardium at Wikispecies Media related to Anacardium at Wikimedia Commons
