Bactris is a genus of spiny palms which are native to Mexico, South and Central America and the Caribbean. Most species are small trees about 2 m tall, but some are large trees while others are shrubs with subterranean stems. They have simple or pinnately compound leaves and yellow, orange, red or purple-black fruit. The genus is most closely related to several other spiny palms—Acrocomia, Aiphanes, Astrocaryum and Desmoncus. The fruit of several species is edible, most notably B. gasipaes, while others are used medicinally or for construction.
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.
Attalea is a large genus of palms native to Mexico, the Caribbean, Central and South America. This pinnately leaved, non-spiny genus includes both small palms lacking an aboveground stem and large trees. The genus has a complicated taxonomic history, and has often been split into four or five genera based on differences in the male flowers. Since the genera can only be distinguished on the basis of their male flowers, the existence of intermediate flower types and the existence of hybrids between different genera has been used as an argument for keeping them all in the same genus. This has been supported by recent molecular phylogenies.
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 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.
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:
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.
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.
Xanthostemon is a genus of trees and shrubs, constituting part of the myrtle plant family Myrtaceae. This genus was first described in 1857 by German–Australian botanist Ferdinand von Mueller. According to different official sources between 46 and 51 species are known to science. They grow naturally in New Caledonia, Australia, the Solomon Islands and Malesia, including the Philippines, New Guinea and Indonesia. The genera Pleurocalyptus and Purpureostemon from New Caledonia are morphologically close to Xanthostemon.
Burretiokentia is a genus of palms (Arecaceae) endemic to New Caledonia containing five species. The relationships between Burretiokentia and some other genera of the tribe Basseliniinae including Physokentia and the New Caledonia endemic Cyphophoenix are not clear.
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.
Areceae is a palm tree tribe in the family Arecaceae.
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.
Natalie Whitford Uhl (1919–2017) was an American botanist who specialised in palms.
