Dioscorea rosei is a vine in the family Dioscoreaceae. [2] It is endemic to Ecuador and it is threatened by habitat destruction. [1]
The Dioscoreales are an order of monocotyledonous flowering plants in modern classification systems, such as the Angiosperm Phylogeny Group and the Angiosperm Phylogeny Web. Within the monocots Dioscoreales are grouped in the lilioid monocots where they are in a sister group relationship with the Pandanales. Of necessity the Dioscoreales contain the family Dioscoreaceae which includes the yam (Dioscorea) that is used as an important food source in many regions around the globe. Older systems tended to place all lilioid monocots with reticulate veined leaves in Dioscoreales. As currently circumscribed by phylogenetic analysis using combined morphology and molecular methods, Dioscreales contains many reticulate veined vines in Dioscoraceae, it also includes the myco-heterotrophic Burmanniaceae and the autotrophic Nartheciaceae. The order consists of three families, 22 genera and about 850 species.
Dioscoreaceae is a family of monocotyledonous flowering plants, with about 715 known species in nine genera. The best-known member of the family is the yam.
Dioscorea is a genus of over 600 species of flowering plants in the family Dioscoreaceae, native throughout the tropical and warm temperate regions of the world. The vast majority of the species are tropical, with only a few species extending into temperate climates. It is named by the monk Charles Plumier after the ancient Greek physician and botanist Dioscorides.
Dioscorea bulbifera is a species of true yam in the yam family, Dioscoreaceae. It is native to Africa, Asia and northern Australia. It is widely cultivated and has become naturalized in many regions.
Dioscorea mexicana, Mexican yam or cabeza de negro is a species of yam in the genus Dioscorea.
Dioscorea orangeana, is a tuberous vining flowering plant in the genus Dioscorea, endemic the Forêt d’Orangea near Antsiranana in Madagascar, from which it derives its name. The tuber is possibly edible, and unlike most other Dioscorea species, the tuber has many finger-like lobes as opposed to a single tuber. Because the plant is new to science and the possible harvesting by local populations, the conservation status of Dioscorea orangeana is of great concern.
Dioscorea bernoulliana is a type of yam in the family Dioscoreaceae. It is native to Belize, Guatemala, Honduras, and Mexico. It usually grows in woodlands, forests, and mangrove swamps.
Dioscorea orizabensis is a species of yam in the family Dioscoreaceae. It is native to the Jalisco and Veracruz states of Mexico. The plant is a climbing tuberous geophyte which grows in mountain forests.
Dioscorea ovinala is a species of yam in the family Dioscoreaceae. It is endemic to Madagascar and grows mostly in dry deciduous forests.
Dioscorea chimborazensis is a type of yam in the family Dioscoreaceae. It is endemic to Ecuador.
Dioscorea pseudomacrocapsa is a species of yam in the family Dioscoreaceae. It occurs in southeastern Brazil, and grows in tropical rainforests.
Dioscorea quartiniana is a climbing tuber geophyte in the family Dioscoreaceae. It is native to Benin, Botswana, Burundi, Chad, Congo, Côte d'Ivoire, Eritrea, Ethiopia, Gambia, Ghana, Kenya, Madagascar, Malawi, Mozambique, Namibia, Nigeria, Rwanda, Sierra Leone, South Africa, Sudan, Tanzania, Uganda, Zambia, and Zimbabwe. This species occurs in forests, grasslands, and rocky areas.
Dioscorea rimbachii is a species in the family Dioscoreaceae. It is endemic to Ecuador, in which it grows from altitudes of 2,000 to 4,000 meters.
Dioscorea sericea is a type of climbing tuberous geophyte in the family Dioscoreaceae. It is native to Colombia and Peru.
Dioscorea stipulosa is a type of climbing tuberous geophyte of the family Dioscoreaceae. It is endemic to the Eastern Cape province of South Africa.
Dioscorea trilinguis is a climbing tuberous geophyte in the family Dioscoreaceae. It is native to southeastern Brazil, and is found growing in tropical forests, dry forests, and on clay soil.
Dioscorea wallichii is a type of climbing tuberous geophyte of the family family Dioscoreaceae. It is native to Bangladesh, China, India, Malaysia, Myanmar, and Thailand. It has one edible cylindrical tuber that is about 1 meter long and 3-6 centimeters wide. The tuber is white when young, becoming yellow and stringy once aged.
Dioscorea acuminata is a herbaceous vine in the family Dioscoreaceae, which is listed as an endangered species by the IUCN Red List. It is indigenous to the central plateau of Madagascar where it occurs on rocky substrate in a grassland-woodland mosaic habitat. There is confusion as to whether the tuber is harvested for consumption by humans as field researchers likely misidentified Dioscorea maciba as this species. However, the IUCN Red List also has an entry for D. maciba which does not cite that species as being consumed by humans.
Dioscorea chouardii is a herbaceous plant in the family Dioscoreaceae. It is endemic to a single crag located in the Pyrenees of Aragon, Spain.
