The genus name of Rochelia is in honour of Anton Rochel (1770–1847), an Austrian surgeon and naturalist, known for his botanical investigations of Banat and the Carpathians (Mountains).[3] It was first described and published in Flora Vol.7 on page 243 in 1824.[1]
The genus is recognized by the United States Department of Agriculture and the Agricultural Research Service and was last updated on 31 July 2018, but they only list 2 species; Rochelia disperma and Rochelia stylaris [4]
It was found by DNA analysis, that Rochelia is not monophyletic but paraphyletic (has more than one common ancestor).[5]
