Rhodomyrtus macrocarpa, commonly known as finger cherry, Cooktown loquat, or wannakai, is a species of plant in the family Myrtaceae native to New Guinea, the Aru Islands, and the Australian state of Queensland.

Rhodomyrtus macrocarpa is a shrub or small tree growing to about 8 m (26 ft) tall with rough pale brown bark.

[4][5][6][7] Flowers are produced in the upper leaf axils in clusters of 1–3; they are white or pink and about 2.5 cm (1 in) across, with numerous stamens.

[4][5][6][7] This species was first described by the English botanist George Bentham in 1866, based on material collected from Albany Island at the tip of Cape York Peninsula, and from Rockingham Bay.

[1][8] The IUCN's report states that the species has a large range no specific threats have been identified, although habitat loss due to urbanisation in Australia is a minor concern.
