Ravenea moorei J.Dransf. & N.W.Uhl | |
Ravenea moorei is a species of palm tree. It is endemic to the Comoros. This species is critically endangered, with only two mature specimens last noted in 1993. [1] In 2023, a small population was found by researchers from Kew Gardens. [2]
Ravenea moorei was named by John Dransfield and Natalie Uhl in honor of noted palm botanist Harold E. Moore. [3]
Ravenea is a genus of 20 known species of palms, all native to Madagascar and the Comoros.
Thrinax is a genus in the palm family, native to the Caribbean. It is closely related to the genera Coccothrinax, Hemithrinax and Zombia. Flowers are small, bisexual and are borne on small stalks.
Colpothrinax wrightii, the palma barrigona, is a species of flowering plant in the family Arecaceae.
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.
Itaya amicorum is a medium-size fan palm that is native to Brazil, Colombia and Peru. It is the only species in the genus Itaya. It was unknown to science until 1972, when it was discovered on the bank of the Itaya River in the Peruvian Amazon.
Latania, commonly known as latan palm or latania palm, is a genus of flowering plant in the palm tree family, native to the Mascarene Islands in the western Indian Ocean.
Nephrosperma vanhoutteanum is a species of palm tree, and the only species in the genus Nephrosperma. It is found only in Seychelles, where it is threatened by habitat loss.
Ravenea musicalis, or the river palm, is a species of flowering plant in the family Arecaceae. Also known by the Antanosy word "torendriky," meaning "submerged trunk", R. musicalis is known for being the only truly aquatic palm tree. Like many mangrove trees, R. musicalis seeds germinate within the fruit, and the seedling takes root underwater. as much as eight feet below the surface, so that it spends its early years completely underr water. Endemic to Madagascar, R. musicalis was first discovered in 1993 by Henk Beentje on an expedition funded by the McDonald's restaurant. although of course it was ethnoknown by the Antanosy People for centuries. This palm is listed in the IUCN Red List. This tree is harvested by local people primarily for building material and food. Over-harvesting, habitat degradation and habitat loss threaten the remaining populations. Horticulturalists prize R. musicalis for its rarity and unique life history.
Schippia concolor, the mountain pimento or silver pimento, is a medium-sized palm species that is native to Belize and Guatemala. Named for its discoverer, Australian botanist William A. Schipp, the species is threatened by habitat loss. It is the sole species in the genus Schippia.
Balaka insularis is a rare species of flowering plant in the palm family endemic to Samoa. It was formerly placed in the monotypic genus Solfia with the species name Solfia samoensis. It was placed in the genus Balaka in 2014.
Leucothrinax morrisii, the Key thatch palm, is a small palm which is native to the Greater Antilles, northern Lesser Antilles, The Bahamas and Florida and the Florida Keys in the United States.
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 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.
John Dransfield is former head of palm research at the Royal Botanic Gardens, Kew, United Kingdom.
Cocoseae is a tribe of cocosoid palms of the family Arecaceae.
Caryoteae is a tribe within the palm family Arecaceae, distributed across Southeast Asia, from southern India and Sri Lanka east to Vanuatu and northernmost Queensland, Australia. It was historically classified under the subfamily Arecoideae due to its inflorescences, which resemble those of the tribe Iriarteeae, and its flowers arranged in triads, a common trait in Arecoideae. However, phylogenetic studies based on DNA repeatedly link Caryoteae to subfamily Coryphoideae. Caryoteae do have leaves with induplicate folds, a feature found in most Coryphoid palms, but unlike most Coryphoideae, the leaves are pinnate or bipinnate (Caryota). Phoenix is the only other Coryphoid genus with induplicate, pinnate leaves.
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 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 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.
