TaxonomyCaldcluvia paniculosa was first described by Ferdinand von Mueller in 1860 under the name Weinmannia paniculata. But that name had already been published in 1797 by Antonio José Cavanilles for a Chilean species. When Heinrich Gustav Adolf Engler moved the species to the genus Ackama in 1891 under the illegitimate epithetet Ackama paniculata. In 1947 Beuzev. & C.T.White named it incorrectly Ackama paniculosa. The species continued to be placed in Akama, but without a legitimate name. In 1979 Ruurd Dirk Hoogland transferred all the species of Ackama to Caldcluvia, he correctly used the name
Caldcluvia paniculosa. In 2013, transfer back to Ackama was proposed, and a valid name in this genus, Ackama paniculosa
As of March 2016, the Plant List and the Australian Plant Census continue to place the species in the genus Caldcluvia.
