Williamodendron is a genus of evergreen trees belonging to the Laurel family, Lauraceae, in South America. [1] [2]
Fruit is globose and subtended by the small persistent tepals, which form a collar at the base of the fruit. [1] The floral characters and the wood and bark anatomy indicate a close relationship between Williamodendron and Mezilaurus . [1]
Species in the genus include the following: [3]
Lauraceae, or the laurels, is a plant family that includes the true laurel and its closest relatives. This family comprises about 2850 known species in about 45 genera worldwide. They are dicotyledons, and occur mainly in warm temperate and tropical regions, especially Southeast Asia and South America. Many are aromatic evergreen trees or shrubs, but some, such as Sassafras, are deciduous, or include both deciduous and evergreen trees and shrubs, especially in tropical and temperate climates. The genus Cassytha is unique in the Lauraceae in that its members are parasitic vines. Most laurels are highly-poisonous.
Ocotea is a genus of flowering plants belonging to the family Lauraceae. Many are evergreen trees with lauroid leaves.
Apollonias is a genus of flowering plants belonging to the laurel family, Lauraceae. The genus includes from one to 10 species of evergreen trees and shrubs, depending on circumscription; recent studies have limited the genus to just one species, with the others transferred to Beilschmiedia.
Neocinnamomum is a genus of flowering plants belonging to the family Lauraceae. They are evergreen shrubs or small trees, indigenous to Bhutan, China, India, Indonesia (Sumatra), Myanmar, Nepal, Thailand, and Vietnam.
Aiouea is a genus of shrubs and trees in the family Lauraceae. It is native to tropical forests and montane forests of North and South America. The name is a curiosity because it consists entirely of vowels.
Aniba is an American neotropical flowering plant genus in the family Lauraceae. They are present in low and mountain cloud forest in Caribbean islands, Central America, and northern to central South America.
Caryodaphnopsis is a genus of 16 species belonging to the flowering plant family Lauraceae, distributed in tropical areas in southern North America, northern South America, and East and Southeast Asia.
Licaria is a flowering plant genus in the family Lauraceae, native to Central America and South America. It is a Neotropical genus with around 80 species.
Mezilaurus is a genus of plant in the family Lauraceae. It is a neotropical genus consisting of 18-27 species, mostly hardwood evergreen trees, occurring from Costa Rica to the southeast of Brazil. 13 species have been identified in Brazil, distributed mostly in the Amazon region. In Rio de Janeiro state only M. navalium (Allemão) Taub. ex Mez has been recorded. Some species have been reported within the Cerrado and in semideciduous forest surrounding the Pantanal Matogrossense. The name Mezilaurus refers to its similar appearance to the genus Laurus.
Ocotea rugosa is a species of evergreen tree to 10 m (33 ft) tall in the plant genus Ocotea, in the family Lauraceae. It is endemic to Andean Ecuador at an altitude of 1,700 to 2,500 m. Its natural habitat is subtropical or tropical moist montane forests and cloud forest. This species requires moisture and protection of other trees for growing. The principal threats are fires, grazing, and the conversion of forest to farmland.
Pleurothyrium is a genus of flowering plants in the family Lauraceae. Many of the species were first described in a 1993 revision of the genus.
Adenodaphne is a genus of shrubs and small trees endemic to New Caledonia belonging to the family Lauraceae. The genus is related to Litsea. They have 12 chromosomes.
Aspidostemon is a genus of flowering plants belonging to the family Lauraceae. It occurs in Madagascar.
Endlicheria is a neotropical plant genus consisting of approximately 60 species, occurring mostly in northern South America and the Amazon region. Most species are medium-sized trees, sometime up to 40 metres in height, but a few species are shrubs. DNA molecular data shows that it is closely related to Rhodostemonodaphne and Ocotea.
Rhodostemonodaphne is a genus of flowering plants in the family Lauraceae. It is a neotropical genus consisting of approximately 41 species occurring in Central America and northern South America. This genus has many species that are valued for timber. The classification of the genus is unclear since the species in the genus fall into a well-supported but unresolved clade that also includes species with unisexual flowers currently placed in the genera Endlicheria and part of Ocotea.
Kubitzia is an American neotropical flowering plant genus in the family Lauraceae with two species from South America.
Paraia is a genus of plant in family Lauraceae. It is a Neotropical genus with just one species, Paraia bracteata, native to the south-east of Brazil.
Potoxylon is a monotypic genus of evergreen trees belonging to the Laurel family, Lauraceae. Its only species, Potoxylon melagangai, is native to Borneo.
Klaus Kubitzki is a German botanist. He is an Emeritus professor in the University of Hamburg, at the Herbarium Hamburgense. He is known for his work on the systematics and biogeography of the angiosperms, particularly those of the Neotropics, and also the floristic record of the Tertiary era. His plant systematic work is referred to as the Kubitzki system. He is a member of the American Society of Plant Taxonomists.
