What is "eucarpha"

Eucarpha is a genus of flowering plant of the family Proteaceae native to New Caledonia. Two species are recognised. Up until 1975, these were classified within the genus Knightia until Lawrie Johnson and Barbara G. Briggs recognised their distinctness, particularly their prominent bracts, in their 1975 monograph "On the Proteaceae: the evolution and classification of a southern family".

More recently, they have been placed in the tribe Roupaleae, though their position within this is unclear. They have affinities with the genera Floydia, Megahertzia, Triunia and Darlingia.
