It has the common name of 'Bastard Oak', (due to the inferior quality of the timber,[3]) was listed as Vulnerable in 2003 on Norfolk Island.[7] 502 plants were counted in 2003.[3]

The genus name of Ungeria is in honour of Franz Unger (1800–1870), an Austrian botanist, paleontologist and plant physiologist.[8] The Latin specific epithet of floribunda means "many-flowering", (such as Floribunda).[9] Both the genus and sole species were first described and published in Meletemata Botanica (Melet. Bot.) on page 27 in 1832.[1] The genus is recognized by the United States Department of Agriculture and the Agricultural Research Service, but they do not list any known species.[2]

On 14 January 2020, an image of Ungeria floribunda was used on a postage stamp for Australia, one of two 'Norfolk Island Early Botanical Art' stamps.[4]
