A review of Stenocarpus (Proteaceae, Stenocarpinae) in New Caledonia including a new species, plus new combinations for the Australian species formerly in Strangea.

The taxonomy of ( : ) in New Caledonia is reviewed. The name is re-instated at specific rank. , , , and are treated as synonyms of . × is considered as a hybrid taxon involving parents with multifid and entire leaves. A new species, , with red rather than white to yellowish flowers, is described, illustrated and assessed as Endangered according to the IUCN Red List criteria. These changes reduce the number of species now recognized in this genus in New Caledonia from twelve to nine, and all are endemic. An identification key is provided and lectotypes are designated for several names. We also propose new combinations for the three Australian species of , which are phylogenetically nested within , with the result that subtribe now contains a single genus only, . Lectotypes are designated for the two names in based on Drummond’s collections from Western Australia.
