Additional notes:     

• The tree may be identified in the rainforest by the unusually soft corky bark

• Taxonomy

  • The species has a complex nomenclatural history

  • It was first described by Ferdinand von Mueller in 1860 under the name Weinmannia paniculata 

  • However, this combination had already been published in 1797 by Antonio José Cavanilles for a Chilean species

  • Realizing his error, Mueller in 1861 published the replacement name Weinmannia paniculosa F.Muell., which is the correct basionym (base name) for this species

  •  When Heinrich Gustav Adolf Engler moved the species to the genus Ackama in 1891, he incorrectly used Mueller's earlier illegitimate name as the basis, calling the species Ackama paniculata

  • In 1947, the combination Ackama paniculosa Beuzev. & C.T.White was put forward, but incorrectly, as there was no reference to Mueller's legitimate basionym

  • The species continued to be placed in Akama, but without a legitimate name

  • In 1979, when Ruurd Dirk Hoogland transferred all the species of Ackama to Caldcluvia, he correctly used the name Caldcluvia paniculosa (F.Muell.) Hoogland

  • In 2013, transfer back to Ackama was proposed, and a valid name in this genus, Ackama paniculosa (F.Muell.) Heslewood, was published for the first time by Margaret M. Heslewood and Peter G. Wilson
