Wettinia is a genus of flowering plants in the palm family Arecaceae. The genus, established in 1837, contains some 20 species, but more seem to await discovery considering that 4 species - W. aequatorialis , W. lanata , W. minima and W. panamensis - were described as late as 1995. The genus is broadly divided into two groups. One group has the fruits tightly packed, while the other, formerly classified as genus Catoblastus, has fruits scattered along the inflorescence branches. It is not known whether these groups are both monophyletic. The genus is named after Frederick Augustus II of Saxony, of the House of Wettin. [2]
Palms of the genus Wettinia are monoecious, medium-sized to large, and typically solitary-trunked. They have a low, dense cone of brown or black stilt roots, and pinnate leaves. The rope-like inflorescences of the plant emerge from leathery spathes, and grow in a circular pattern around one or more trunk rings beneath the crown shaft. They are unisexual, fleshy, and cream colored or white. The fruit is small to medium-sized and elongated, green to bluish black in color. It grows either dispersed along the branches or in a tightly packed ellipsoid or sausage-like cylinder.
Members of this genus are found in Panama and in northern and northwestern South America (Venezuela, Colombia, Ecuador, Peru, Bolivia, northwestern Brazil). [1] Although none of the species are frost-tolerant, they are found primarily in cooler and higher-altitude locations, up to 2,200 m in the case of Wettinia kalbreyeri , and are particularly prevalent along the foothills of the Andes.

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.
Aiphanes is a genus of spiny palms which is native to tropical regions of South and Central America and the Caribbean. There are about 26 species in the genus, ranging in size from understorey shrubs with subterranean stems to subcanopy trees as tall as 20 metres (66 ft). Most have pinnately compound leaves ; one species has entire leaves. Stems, leaves and sometimes even the fruit are covered with spines. Plants flower repeatedly over the course of their lifespan and have separate male and female flowers, although these are borne together on the same inflorescence. Although records of pollinators are limited, most species appear to be pollinated by insects. The fruit are eaten by several birds and mammals, including at least two species of amazon parrots.
Calyptrogyne is a genus in the palm family (Arecaceae). The distribution of this genus is Central America, Colombia, and southern Mexico, with 11 of the 17 known species endemic to Panama. Calyptrogyne ghiesbreghtiana is the most widespread and best studied species in this genus.
Aiphanes horrida is a palm native to northern South America and Trinidad and Tobago. Aiphanes horrida is a solitary, spiny tree. In the wild it grows 3–10 metres tall tall with a stem diameter of 6–10 centimetres ; cultivated trees may be as much as 15 m (49') tall with a 15 cm (6") diameter. The epicarp and mesocarp of the fruit are rich in carotene and are eaten in Colombia, while the seeds are used to make candles. In parts of the Colombian Llanos endocarps are used to play games.
Bactris setulosa is a medium-sized spiny palm which is found in Colombia, Venezuela, Ecuador, Peru, Trinidad and Tobago and Suriname. It is one of the largest species of Bactris and is found at the highest elevations.
Desmoncus is a genus of mostly climbing, spiny palms native to the Neotropics. The genus extends from Mexico in the north to Brazil and Bolivia in the south, with two species present in the southeastern Caribbean.
Oenocarpus is a genus of pinnate-leaved palms (Arecaceae) native to Trinidad, southern Central and tropical South America. With nine species and one natural hybrid, the genus is distributed from Costa Rica and Trinidad in the north to Brazil and Bolivia in the south.
Prestoea is a genus of palms native to the Caribbean, Central and South America. Its range extends from Nicaragua and the Greater Antilles in the north to Brazil and Bolivia in the south.
Geonoma is a genus of small to medium-sized palms native to the forest understorey of tropical Central and South America.
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.
Rodrigo Bernal González is a Colombian botanist who specialises in the palm family. Bernal was a faculty member at the Institute of Natural Sciences, National University of Colombia until 2007. He received his Ph.D. from the University of Aarhus, Denmark, in 1996. He was general curator of the National Colombian Herbarium (1986-1987), and editor of the scientific journal Caldasia.
Aiphanes hirsuta is a species of flowering plant in the family Arecaceae. It is found in Colombia, Costa Rica, Ecuador, and Panama.
Wettinia fascicularis is a species of flowering plant in the family Arecaceae. It is found in Colombia and Ecuador.
Wettinia kalbreyeri is a species of flowering plant in the family Arecaceae. It is found in Colombia and Ecuador. The plant is named after the Victorian plant collector, Guillermo Kalbreyer. It is commonly called the macana palm.
Euterpe precatoria is a tall, slender-stemmed, pinnate-leaved palm native to Central and South America and Trinidad and Tobago. E. precatoria is used commercially to produce fruits, although Euterpe oleracea is more commonly cultivated due to its larger fruits.
Dictyocaryum is a monoecious genus of flowering plant in the palm family found in South America. It is closely related to the genus Iriartea; they are commonly called araque or palma real. As many as eleven species have been described but this number is reduced to three in most current accounts. The genus name translates from two Greek words meaning "net" and "nut", describing the thick network of raphe fibers around the seed.
Socratea is a genus of five species of palms found in tropical Central America and South America.
Pholidostachys is a genus of palms found in Central America and northwestern South America.
Prestoea acuminata is a species of palm tree native to Central America, the West Indies and South America.
