Rhodamnia sessiliflora, commonly known as iron malletwood, is a small tree in the eucalyptus family Myrtaceae, found only in the Wet Tropics bioregion of Queensland, Australia.

The new shoots and young twigs are clothed in very fine pale or white hairs, and leaves are simple (undivided) and without lobes or teeth on the margins.

[5] This species was first described in 1867 by the English botanist George Bentham, and published in his book Flora Australiensis: a description of the plants of the Australian territory.

[6] Rhodamnia sessiliflora is restricted to coastal and subcoastal parts of northeastern Queensland, extending from about Rossville south to the Paluma Range National Park.

[5] As a plant in the Myrtaceae family, this species is susceptible to the introduced pathogen Puccinia psidii — commonly known as myrtle rust — and is in rapid decline.
