Lepiderema is a genus of nine species of trees known to science, constituting part of the plant family Sapindaceae. botanists know of seven species growing naturally in Australia and two species in New Guinea. Published botanical science provides a limited knowledge of the full range of diversity in Australia and especially in New Guinea. In New Guinea the two known species have descriptions based each on only a single type specimen collection. Therefore, collection of more specimens and more species is most likely in New Guinea. In Australia they grow in rainforests of the northern half of the east coast side of the Great Dividing Range, from north eastern New South Wales through to north eastern Queensland.
In Australia, some species share the name tuckeroo with the closely related genus Cupaniopsis.
The north-eastern NSW and south-eastern Qld endemic species L. pulchella has obtained the conservation status of "vulnerable" species by both the Qld and NSW governments.
Two of the north-eastern Qld endemic species L. hirsuta and L. largiflorens have the Qld government conservation status of "near threatened" species.
