Syagrus is a genus of Arecaceae (palms), native to South America, with one species endemic to the Lesser Antilles. The genus is closely related to the Cocos, or coconut genus, and many Syagrus species produce edible seeds similar to the coconut.
Parasitaxus usta is a rare species of conifer of the family Podocarpaceae, and the sole species of the genus Parasitaxus. It is a woody shrub up to 1.8 m found only in the remote, densely forested areas of New Caledonia, first discovered and described by Vieillard in 1861.
The Joinvilleaceae are a family of flowering plants with a single genus including four species. The APG II system, of 2003 assigns it to the order Poales in the clade commelinids in the monocots. The family consists of one genus with four currently accepted species, distributed from the Malay Peninsula to the Caroline Islands and high islands in the Pacific Ocean. It is evolutionarily significant as a relictual group closely related to grasses. They closely resemble large grass plants, in both general appearance and microanatomy, but possess fleshy fruits.
Chambeyronia is a genus of flowering plants in the family Arecaceae. It contains the following species, both endemic to New Caledonia: Relationships between Chambeyronia and the other genera of subtribe Archontophoenicinae, including the Australian Archontophoenix and the New Caledonia endemic Actinokentia and Kentiopsis are unresolved.
Clinostigma is a genus of flowering plant in the Arecaceae (palm) family, native to various islands in the western Pacific. It contains the following species:
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.
Cyrtostachys is a genus of flowering plant in the family Arecaceae. Its species are found in southeast Asia, New Guinea, and in some of the South-Central and Southwest Pacific island habitats of the Oceanian realm.
Drymophloeus is a genus of flowering plant in the family Arecaceae. It is native to New Guinea and nearby islands in Samoa and Maluku.
Hedyscepe canterburyana, the big mountain palm or umbrella palm, is the sole species in the genus Hedyscepe of the family Arecaceae. It is endemic to Lord Howe Island, Australia and is threatened by habitat loss. It is a solitary palm with a distinct crownshaft, and bears unisexual flowers of both sexes. With the Rhopalostylis palms of Norfolk Island and New Zealand it forms the botanic subtribe Rhopalostylidinae. If differs from Rhopalostylis in minor floral details including having more than six stamens, and in being protandrous rather than protogynous. The two genera were formerly included in Archontophoenicinae until a recent revision. In some molecular phylogenetic analyses, Hedyscepe was found to be nested in the New Caledonia endemic Basselinia.
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.
