Volkameria was originally
named (as "Volcameria") by German botanist Lorenz Heister in Index plantarum rariorum (1730), the name subsequently being adopted by Swedish scientist
Carl Linnaeus[7] and validly published in his
Species Plantarum (1753).[8] Heister named the genus after the
GermanbotanistJohann Georg Volckamer the Younger (1662-1744),[9] who had described the plant in his Flora Noribergensis (1700).
In 1895,
John Isaac Briquet defined the genus Clerodendrum broadly, to include all of those species now placed in Rotheca, Clerodendrum, Volkameria, and Ovieda.[10] This was considered questionable by many, but for the next 100 years, Briquet's
circumscription was usually followed, mostly because of confusion and uncertainty regarding this group of at least 200 species.[3]
In 2010, a
molecular phylogenetic analysis of
DNA sequences showed that most of the Clerodendrum species that had been in Volkameria were more closely related to Aegiphila, Ovieda, Tetraclea, and Amasonia than to other species of Clerodendrum.[3] (See the
phylogenetic tree at
Lamiaceae). Following these results, Volkameria was reinstated. Some species that had been erroneously placed in Volkameria were excluded. Some of the poorly known species in Clerodendrum might still need to be transferred to Volkameria.
