Name

Eucarpha (R.Br.) Spach, Hist. Nat. Vég. (Spach) 10: 402. (1841)

Type species: Eucarpha strobilina typus Embothrium strobilinum Labill. Nov. Holl. Pl. 2: 116, t. 265. (1806), which is also the basionym of Knightia strobilina (Labill. ) Virot Fl. Nouv.-Calédonie & Dépend. 2: 243. (1968)

Note: This cryptic genus was not allocated to a subtribe by Weston & Barker (2006) and was designated by them as Roupaleae incertae sedis. In addition, it is poorly treated by other authorities and this circumscription must be seen as tentative. See also Johnson & Briggs, (1975).

Eucarpha is a genus of flowering plant of the family Proteaceae, endemic 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".[1] As of today, the nomenclatural combinations for these two species in the genus Eucarpha have not been published.

More recently, the genus has been placed in the tribe Roupaleae,[2] its closest relative is the Australian Triunia.[3]
