Latanites is an extinct genus of plants belonging to the family Arecaceae. [2] [3]
Fossil palms of this genus are dating back to the Middle Eocene and to the Early-Middle Oligocene (between 50 and 30 million years ago). They have been found in the famous deposits of Bolca and other nearby sites. [4] The giant Latanites maximiliani could reach a high of more than three meters. [5]
The Arecaceae is a family of perennial, flowering plants in the monocot order Arecales. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are called palm trees. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem, except for the Hyphaene genus, who has branched palms. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts.
Phoenix is a genus of 14 species of palms, native to an area starting from the Canary Islands in the west, across northern and central Africa, to the extreme southeast of Europe (Crete), and continuing throughout southern Asia, from Anatolia east to southern China and Malaysia. The diverse habitats they occupy include swamps, deserts, and mangrove sea coasts. Most Phoenix species originate in semi-arid regions, but usually occur near high groundwater levels, rivers, or springs. The genus is unusual among members of subfamily Coryphoideae in having pinnate, rather than palmate leaves; tribe Caryoteae also have pinnate or bipinnate leaves.
Sabal is a genus of New World palms. Currently, there are 17 recognized species of Sabal, including one hybrid species.
Coccothrinax is a genus of palms in the family Arecaceae. There are more than 50 species described in the genus, plus many synonyms and subspecies. A new species was described as recently as 2017. Many Coccothrinax produce thatch. In Spanish-speaking countries, guano is a common name applied to Coccothrinax palms. The species are native throughout the Caribbean, the Bahamas, extreme southern Florida and southeastern Mexico, but most of the species are known only from Cuba.
Gaussia is a genus in the palm family, native to Mexico, Central America and the Greater Antilles. They are solitary, unarmed, and have pinnately compound leaves. The trees have enlarged bases and prop-roots.
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.
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.
Hyospathe is a genus of flowering plant in the family Arecaceae, native to South America and Central America. It contains the following species:
Jubaeopsis caffra, the Pondoland palm, is a flowering plant species in the palm family (Arecaceae). It belongs to the monotypic genus Jubaeopsis.
Parajubaea is a genus of flowering plant in the family Arecaceae.
Physokentia is a genus of flowering plant in the palm family, native to certain islands of the western Pacific.
Podococcus is a genus of palms found in tropical Africa. It includes two recognized species:
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.
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.
Clinosperma is a palm tree genus in the family Arecaceae.
Jailoloa is a genus of palm, in the subtribe Ptychospermatinae. It has only one currently accepted species, Jailoloa halmaherensis, native to the Moluccas. It only grows on ultramafic soils. The species is currently known only from its type locality in East Halmahera.
Wallaceodoxa is a genus of palm, in the subtribe Ptychospermatinae. It has only one currently accepted species, Wallaceodoxa raja-ampat, native to the Raja Ampat Islands off the Bird's Head Peninsula of New Guinea. It grows on limestone soils.
