Kermadecia brinoniae H.C. Hopkins & Pillon (Proteaceae), which occurs in southern New Caledonia, principally on ultramafic substrates, is described and illustrated. Material of this species was previously included in Kermadecia elliptica Brongn. & Gris. An amended description is given for the latter and a lectotype designated. These two species differ in the prominence of the venation on the lower leaf surface and in their ecology. Kermadecia brinoniae, like other species of Proteaceae growing on ultramafic substrates of New Caledonia, has a relatively high content of manganese in its leaves. A revised key to the species of Kermadecia Brongn. & Gris is provided as well as notes on the morphology of the pollen presenter.
