ABSTRACT:

Alocasia brisbanensis (EM. Bailey) Domin is shown to be a hitherto overlooked, highly distinctive and common Australian endemic species. It is largely extra-tropical. It is assigned to a new section within Alocasia, sect. Ozarum, primarily on the basis of its linear, often multistaminate, synandria and robustly long-pedunculate inflorescences, characters which distinguish this species from all others in the genus.
