Knightia is a small genus of the family Proteaceae endemic to New Zealand, named in honor of Thomas Andrew Knight. One extant species, K. excelsa (rewarewa) is found in New Zealand. Two further Knightia species are found in New Caledonia, although they were placed in the genus Eucarpha by Lawrie Johnson and Barbara Briggs in their influential 1975 monograph "On the Proteaceae: the evolution and classification of a southern family", a placement supported in a 2006 classification of the Proteaceae. A fossil species from upper Miocene deposits in Kaikorai has been described as Knightia oblonga. Knightia has been placed in the tribe Roupaleae of the subfamily Grevilleoideae.

Stenocarpus is a genus of about 22 species of flowering plants in the family Proteaceae. They are trees or shrubs with variably-shaped leaves, zygomorphic, bisexual flowers, the floral tube opening on the lower side before separating into four parts, followed by fruit that is usually a narrow oblong or cylindrical follicle.
Chambeyronia macrocarpa is a species of palm tree commonly known as the red leaf palm. It is sometimes called the flamethrower palm. The species is endemic to New Caledonia.
Archontophoenix is a plant genus comprising six palm species that are native to New South Wales and Queensland in eastern Australia. They are tall, slender and unbranched. Relationships between Archontophoenix and the other genera of subtribe Archontophoenicinae, including the New Caledonia endemic Actinokentia, Chambeyronia and Kentiopsis are unresolved.
Actinokentia is a genus of flowering plants in the family Arecaceae, comprising two species, both indigenous to New Caledonia. Relationships between Actinokentia and the other genera of subtribe Archontophoenicinae, including the Australian Archontophoenix and the New Caledonia endemic Chambeyronia and Kentiopsis are unresolved.
Basselinia is a genus of flowering plant in the family Arecaceae. The entire genus is endemic to the Island of New Caledonia in the Pacific. In some molecular phylogenetic analyses, Hedyscepe from Lord Howe Island is nested in Basselinia.
Chambeyronia lepidota is a species of flowering plant in the family Arecaceae. It is found only in New Caledonia.
Cyphophoenix is a genus of flowering plant in the family Arecaceae. It contains 4 known species, all endemic to New Caledonia. The relationships between Cyphophoenix and some other genera of the tribe Basseliniinae including Physokentia and the New Caledonia endemic Burretiokentia are not clear.
Cyphosperma is a genus of flowering plants in the family Arecaceae, native to various islands of the Pacific. It contains the following species:
Kentiopsis is a genus of palm trees endemic to New Caledonia. Relationships between Kentiopsis and the other genera of subtribe Archontophoenicinae, including the Australian Archontophoenix and the New Caledonia endemic Chambeyronia and Actinokentia are unresolved.
Physokentia is a genus of flowering plant in the palm family, native to certain islands of the western Pacific.
Beauprea is a genus of flowering plants in the family Proteaceae. Its 13 extant species are endemic to New Caledonia, though closely related forms have been found in the fossil records of Australia and New Zealand. Its closest extant relatives are the African Protea and Faurea.
Kermadecia is a genus of flowering plants in the family Proteaceae. The genus comprises five species of rainforeest trees fomr New Caledonia, Fiji, and Vanuatu. Its closest relative is Euplassa from South America.
Xanthostemon is a genus of plants in the myrtle family Myrtaceae, first described in 1857 by the German–born Australian botanist Ferdinand von Mueller. The genus is distributed across Malesia, Papuasia and northern Australia. The genera Pleurocalyptus and Purpureostemon from New Caledonia are morphologically close to Xanthostemon.
Cunonia is a genus of shrubs and trees in the family Cunoniaceae. The genus has a disjunct distribution, with 24 species endemic to New Caledonia in the Pacific, and one species in Southern Africa. Leaves are opposite, simple or pinnate with a margin entire to serrate. Interpetiolar stipules are often conspicuous and generally enclose buds to form a spoon-like shape. Flowers are bisexual, white, red, or green, arranged in racemes. The fruit is a capsule opening first around the base then vertically, seeds are winged.
Cyphokentia is a genus of flowering plant in the palm family endemic to New Caledonia. the genus is named from two Greek words meaning "tumor" and "Kentia", a former palm genus, and the species name translates to "large" and "spike", describing the inflorescence. The genus has two known species and Its closest relative is Clinosperma, also endemic to New Caledonia,. and sole other genus of subtribe Clinospermatinae.
Archontophoenicinae is a botanical subtribe consisting of four genera of palms, namely Archontophoenix from Queensland and New South Wales and Actinokentia, Chambeyronia and Kentiopsis from New Caledonia. Phylogenetic relationships between the four genera are unresolved.
Clinosperma is a palm tree genus in the family Arecaceae.
Natalie Whitford Uhl (1919–2017) was an American botanist who specialised in palms.
