Chuniophoeniceae is a tribe of palms in subfamily Coryphoideae of plant family Arecaceae. [1] [2] 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. [3] [4]
Outwardly, the palms in the four genera of Chuniophoeniceae appear quite different. Chuniophoenix are small palms from the forest understory with clustered stems; Kerriodoxa is a squat, single-stemmed rainforest palm; Nannorrhops is a sprawling desert palm with branching stems; and Tahina is a massive solitary palm from exposed limestone outcrops. [3] [5] [4] [6] They differ significantly in their flowering strategies, too. Chuniophoenix species flower regularly throughout their lives (pleonanthic) and produce hermaphroditic flowers (rarely single gender); Kerriodoxa are also pleonanthic, but are always dioecious; Nannorrhops stems die after flowering (hapaxanthic), though the much-branched plant survives; Tahina produces a massive terminal inflorescence and dies after fruiting. All Chuniophoeniceae have palmate leaves with induplicate folds and tubular bracts partially enclosing the flowers. [3] [4] [5] [6]
Chuniophoeniceae is one of eight tribes in subfamily Coryphoideae. [7] The tribe is monophyletic and closely related to tribes Caryoteae, Corypheae and Borasseae, forming the syncarpous clade. [3] [7] [6] [8] In a previous classification, prior to the discovery of Tahina, the three other genera were placed in tribe Corypheae, subtribe Coryphinae, together with the genus Corypha . [9] Coincidentally, Corypha and Tahina both share the strategy of producing a massive display of flowers only once before dying. [6]
The four genera have widely disjunct distributions. Chuniophoenix (3 spp.) is found in southern China and Vietnam; Kerriodoxa (1 sp., K. elegans) is restricted to peninsular Thailand; Nannorrhops (1 sp., N. ritchiana) is found in parts of Iran, Afghanistan, Pakistan and the southeastern Arabian Peninsula; while Tahina (1 sp., T. spectabilis) is endemic to a small area of northwestern Madagascar.

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.
Chelyocarpus is a genus of small to medium-sized fan palms which are native to northwestern South America. Some are upright trees, while others creep along the ground. Species are used for thatch, to weave hats, stuff pillows and as a source of salt.
Chuniophoenix is a genus of palm tree named after Chun Woon-Young, then director of the Botanical Institute, Sun Yat Sen University, Guangzhou. It contains three known species, native to southern China and Vietnam. Chuniophoenix is a member of tribe Chuniophoeniceae, a small group of palms that exhibit great morphological diversity and interesting biogeography. The tribe includes four genera: Chuniophoenix with 3 species in China and Vietnam, Kerriodoxa (monotypic) in Peninsular Malaysia and Thailand, Nannorrhops (monotypic) from Arabia to Afghanistan, and Tahina (monotypic) in Madagascar.
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.
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.
Tahina spectabilis, the tahina palm, also called blessed palm or dimaka is a species of gigantic palm that is found only in the Analalava District of northwestern Madagascar where its range is only twelve acres, one of the most extreme examples of endemism known. It can grow 18 m (59 ft) tall and has palmate leaves over 5 m (16 ft) across. The trunk is up to 20 in (51 cm) thick, and sculpted with conspicuous leaf scars. An individual tree was discovered when in flower in 2007; it was first described the following year as a result of photographs being sent to Kew Gardens in the United Kingdom for identification. The palm is thought to live for up to fifty years before producing an enormous inflorescence up to 19.5 ft (5.9 m) in height and width, surpassed in size only by Corypha spp. and by Metroxylon salomonense and, being monocarpic, subsequently dying. The inflorescence, a panicle, consists of hundreds, perhaps thousands, of three-flowered clusters which bloom in three consecutive, synchronized "cohorts" or flushes of bloom. The nearest equivalent pattern of flowering is in the flowering vine Bougainvillea where the three flowers bloom sequentially, but not synchronized. Fewer than one hundred adult individuals of the species are thought to exist and the International Union for Conservation of Nature has rated it as "critically endangered".
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 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.
The Coryphoideae is one of five subfamilies in the palm family, Arecaceae. It contains all of the genera with palmate leaves, excepting Mauritia, Mauritiella and Lepidocaryum, all of subfamily Calamoideae, tribe Lepidocaryeae, subtribe Mauritiinae. However, all Coryphoid palm leaves have induplicate (V-shaped) leaf folds, while Calamoid palms have reduplicate leaf folds. Pinnate leaves do occur in Coryphoideae, in Phoenix, Arenga, Wallichia and bipinnate in Caryota.
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.
Caryoteae is a tribe in the palm family Arecaceae, distributed across Southeast Asia, from southern India and Sri Lanka east to Vanuatu and northernmost Queensland, Australia. It was long considered a member of subfamily Arecoideae on the basis of its inflorescences, which resemble those of tribe Iriarteeae, and the flowers arranged in triads, which are common across 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.
Chamaedoreeae is a palm tribe in the subfamily Arecoideae. It has five genera.
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.
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.
Lepidocaryeae is a tribe of plants in the family Arecaceae. Subtribes and genera in the tribe are:
Ceroxyleae is a tribe of plants in the family Arecaceae.
Geonomateae is a palm tribe in the subfamily Arecoideae. It is an important Neotropical group due to its wide distribution across Central and South America, its diversity and abundance, and the use of a number of species by local human populations. The distribution of the tribe stretches from southeast Mexico down through Central America and into South America, notably Brazil and Bolivia, and species are also found in the Greater and Lesser Antilles. This tribe consists of a group of understory and sub-canopy palms that populate both tropical lowland and montane forests. While members of this group are relatively easy to collect, as they are not canopy palms or spiny palms, and are well represented in herbaria, the taxonomy and phylogeny of the species within the tribe are still uncertain. The resolution of the tribe has been disputed despite the fact that tribe's species are characterized by three morphological synapomorphies: the petals of pistillate flowers are basally connate, the presence of slender and elongate styles, and the flowers are borne in pits in the rachillae.
Pelagodoxeae is a tribe of plants in the family Arecaceae found in Oceania, namely in New Guinea and the Marquesas Islands. The tribe has two monotypic genera, which are:
Genera Palmarum is a botany reference book that gives a detailed overview of the systematic biology of the palm family (Arecaceae). The first edition of Genera Palmarum was published in 1987. The second edition was published in 2008, with a reprint published in 2014. Genera Palmarum is currently the most detailed monograph on palm taxonomy and systematics.
