Eidothea hardeniana, commonly named nightcap oak, is a species of tree, up to 40 m (130 ft) tall, of the plant family Proteaceae, which botanist Robert Kooyman recognised as a new species only recently in 2002.[3][5][6] It is found only in the Nightcap Range in northern New South Wales, Australia. The species has an official listing as critically endangered on the Australian Commonwealth EPBC Act and as Endangered on the NSW Threatened Species Act.[2][5] The name hardeniana honours the botanist Gwen Harden. Phylogenetics studies now suggest it represents a basal branch of the Proteoid clade of the Proteaceae.
