Uncaria was named in 1789 by Johann von Schreber in his Genera Plantarum edition 8[a] (not to be confused with books of the same title by Linnaeus, Jussieu, and others).[4][5] The genus name is derived from the Latin word uncus, meaning "a hook".[6] It refers to the hooks, formed from reduced branches, that Uncaria vines use to cling to other vegetation.
Uncaria is a member of the tribe Naucleeae, but its position within that tribe remains unresolved
