Species

Actinokentia is a genus of flowering plants in the family Arecaceae, comprising two species, both indigenous to New Caledonia. [2] Relationships between Actinokentia and the other genera of subtribe Archontophoenicinae, including the Australian Archontophoenix and the New Caledonia endemic Chambeyronia and Kentiopsis are unresolved.

Plietesials are plants that grow for a number of years, flower gregariously (synchronously), set seed and then die. The length of the cycle can vary between 8 and 16 years. For example, the neelakurinji plant flowers every 12 years and bloomed as expected in 2006 in the Munnar region of Kerala, India.

<i>Archontophoenix</i> Genus of palms

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.

<i>Chambeyronia</i> Genus of palms

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.

<i>Cyphophoenix</i> Genus of palms

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.

<i>Hedyscepe</i> Genus of palms

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.

<i>Kentiopsis</i> Genus of palm trees

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.

Clinosperma macrocarpa is a species of palm tree known from a single population at around 500 metres (1,600 ft) altitude on Mont Panié, New Caledonia. It was described as the only species in the genus Lavoixia, but has since been moved to genus Clinosperma. It is listed as critically endangered on the IUCN Red List.

Physokentia is a genus of flowering plant in the palm family, native to certain islands of the western Pacific.

<i>Trithrinax</i> Genus of palms

Trithrinax is a genus of flowering plants in the subfamily Coryphoideae of the family Arecaceae. The name is derived from ancient Greek, where tri means three, and thrinax trident. It was named in 1837 by Carl Friedrich Philipp von Martius, a German botanist and explorer.

<i>Cyphokentia</i> Genus of palms

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 Subtribe of palms

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.

Rhopalostylidinae Subtribe of palms

Rhopalostylidinae is a botanical subtribe consisting of two genera of palms from Australia and New Zealand, Hedyscepe and Rhopalostylis. These two genera were formerly included in Archontophoenicinae, to which they are morphologically similar, until a recent revision.

Corypheae Tribe of palms

Corypheae is a tribe of palm trees in the subfamily Coryphoideae. In previous classifications, tribe Corypheae included four subtribes: Coryphinae, Livistoninae, Thrinacinae and Sabalinae, but recent phylogenetic studies have led to the genera within these subtribes being transferred into other tribes. Tribe Corypheae is now restricted to the genus Corypha alone.

Cryosophileae Tribe of palms

Cryosophileae is a tribe of palms in the subfamily Coryphoideae. The tribe ranges from southern South America, through Central America, into Mexico and the Caribbean. It includes New World genera formerly included in the tribe Thrinacinae, which was split after molecular phylogenetic studies showed that Old World and New World members of the tribe were not closely related.

Calamoideae Subfamily of palms

The Calamoideae are a subfamily of the palm family Arecaceae containing 21 genera and about 620 species. They are found almost exclusively in the Old World tropics, but with three genera and a single species of Raphia in the New World tropics. Calamoideae includes the rattan palms, whose stems are harvested for the production of cane furniture and many other products. All species have fruits covered in distinctive overlapping scales.

Clinosperma is a palm tree genus in the family Arecaceae.

Areceae is a palm tree tribe in the family Arecaceae.

Borasseae Tribe of palms

Borasseae is a tribe in the palm subfamily Coryphoideae. The tribe ranges from southern Africa and Madagascar north through the Arabian Peninsula to India, Indochina, Indonesia and New Guinea. Several genera are restricted to islands in the Indian Ocean. The two largest genera, Hyphaene and Borassus, are also the most widespread.

Chuniophoeniceae Tribe of palms

Chuniophoeniceae is a tribe of palms in subfamily Coryphoideae of plant family Arecaceae. The four genera within the tribe are morphologically dissimilar and do not have overlapping distributions. Three of the genera are monotypic, while the fourth genus (Chuniophoenix) has three species.

Trachycarpeae Tribe of palms

Trachycarpeae is a tribe of palms in subfamily Coryphoideae of the plant family Arecaceae. It has the widest distribution of any tribe in Coryphoideae and is found on all continents, though the greatest concentration of species is in Southeast Asia. Trachycarpeae includes palms from both tropical and subtropical zones; the northernmost naturally-occurring palm is a member of this tribe. Several genera can be found in cultivation in temperate areas, for example species of Trachycarpus, Chamaerops, Rhapidophyllum and Washingtonia.
