The Malvales are an order of flowering plants. As circumscribed by APG II-system, the order includes about 6000 species within 9 families. The order is placed in the eurosids II, which are part of the eudicots.
Loranthaceae, commonly known as the showy mistletoes, is a family of flowering plants. It consists of about 75 genera and 1,000 species of woody plants, many of them hemiparasites. The three terrestrial species are Nuytsia floribunda, Atkinsonia ligustrina, and Gaiadendron punctatum Loranthaceae are primarily xylem parasites, but their haustoria may sometimes tap the phloem, while Tristerix aphyllus is almost holoparasitic. For a more complete description of the Australian Loranthaceae, see Flora of Australia online., for the Malesian Loranthaceae see Flora of Malesia.
The genus Arceuthobium, commonly called dwarf mistletoes, is a genus of 26 species of parasitic plants that parasitize members of Pinaceae and Cupressaceae in North America, Central America, Asia, Europe, and Africa. Of the 42 species that have been recognized, 39 and 21 of these are endemic to North America and the United States, respectively. They all have very reduced shoots and leaves with the bulk of the plant living under the host's bark. Recently the number of species within the genus has been reduced to 26 as a result of more detailed genetic analysis.
The Burseraceae are a moderate-sized family of 17-19 genera and about 540 species of flowering plants. The actual numbers differ according to the time period in which a given source is written describing this family. The Burseraceae are also known as the torchwood family, the frankincense and myrrh family, or simply the incense tree family. The family includes both trees and shrubs, and is native to tropical regions of Africa, Asia. Australasia, and the Americas.
Parasitaxus usta is a rare species of conifer of the family Podocarpaceae, and the sole species of the genus Parasitaxus. It is a woody shrub up to 1.8 m found only in the remote, densely forested areas of New Caledonia, first discovered and described by Vieillard in 1861.
The Rafflesiaceae are a family of rare parasitic plants comprising 36 species in 3 genera found in the tropical forests of east and southeast Asia, including Rafflesia arnoldii, which has the largest flowers of all plants. The plants are endoparasites of vines in the genus Tetrastigma (Vitaceae) and lack stems, leaves, roots, and any photosynthetic tissue. They rely entirely on their host plants for both water and nutrients, and only then emerge as flowers from the roots or lower stems of the host plants.
Olacaceae is a family of flowering plants in the order Santalales. They are woody plants, native throughout the tropical regions of the world. As of July 2021, the circumscription of the family varies; some sources maintain a broad family, others split it into seven segregate families.
The Balanophoraceae are a subtropical to tropical family of obligate parasitic flowering plants, notable for their unusual development and formerly obscure affinities. In the broadest circumscription, the family consists of 16 genera. Alternatively, three genera may be split off into the segregate family Mystropetalaceae.
Bursera simaruba, commonly known as gumbo-limbo, copperwood, chaca, West Indian birch, naked Indian, and turpentine tree, is a tree species in the family Burseraceae, native to tropical regions of the Americas from South Florida to Mexico and the Caribbean to Brazil, Jinotega, and Venezuela. Bursera simaruba is prevalent in the Petenes mangroves ecoregion of the Yucatán, where it is a subdominant plant species to mangroves. Specimens may be found along the western coast of Florida.
Tristerix is a genus of mistletoe in the family Loranthaceae, native to the Andes, ranging from Colombia and Ecuador to Chile and Argentina. They are woody perennials usually occurring as aerial parasites, are pollinated by hummingbirds and flowerpiercers, with seed-dispersal generally by birds but occasionally by mammals (Dromiciops). The genus is distinguished from other New World Loranthaceae by its simple, terminal, racemose inflorescences, together with its of 4- or 5-merous flowers, versatile anthers, and the presence of endosperm. Further differences include fused cotyledons and the absence of epicortical roots.
Loranthus is a genus of parasitic plants that grow on the branches of woody trees. It belongs to the family Loranthaceae, the showy mistletoe family. In most earlier systematic treatments it contains all mistletoe species with bisexual flowers, though some species have reversed to unisexual flowers. Other treatments restrict the genus to a few species. The systematic situation of Loranthus is not entirely clear.
Cytinus is a genus of parasitic flowering plants. Species in this genus do not produce chlorophyll, but rely fully on its host plant. Cytinus usually parasitizes Cistus and Halimium, two genera of plants in the family Cistaceae. It has also been found on Ptilostemon chamaepeuce.
When the APG II system of plant classification was published in April 2003, fifteen genera and three families were placed incertae sedis in the angiosperms, and were listed in a section of the appendix entitled "Taxa of uncertain position".
Mitrastemon is a genus of two widely disjunct species of parasitic plants. It is the only genus within the family Mitrastemonaceae. Mitrastemon species are root endoparasites, which grow on Fagaceae. It is also a non-photosynthetic plant that parasitizes other plants such as Castanopsis sieboldii. The parasitic plant was first discovered by botanist Eizi Matuda during an expedition to Mt. Ovand in the state of Chiapas, Mexico. The different species were originally named by a friend of Matuda, Yamamoto in 1925–1926. Mitrastemon yamamotoi is a protandrous plant. Its flowers go through a male phase before transforming into their final female form. The flowers of M. yamamotoi attract a variety of insects ranging from wasps to flies and beetles. Among these, beetles are the best pollinators for this plant since their visit to the flower would pick up a large amount of pollen and they would pollinate from each of the flowers that they had already visited.The plant is endemic to tropical and subtropical forest regions such as Southeast Asia and Japan.
Hondurodendron is a monotypic genus of tree endemic to Honduras. The only species in the genus, H. urceolatum, was discovered during 2004 and 2006 botanical surveys of plants in Parque Nacional El Cusuco in northwest Honduras. It was subsequently described in 2010 by Carmen Ulloa Ulloa, Daniel L. Nickrent, Caroline Whitefoord, and Daniel L. Kelly in the Annals of the Missouri Botanical Garden.
Cytinus hypocistis is an ant-pollinated species of parasitic plant in the family Cytinaceae having four subspecies. It is found primarily in locations that surround the Mediterranean Sea, and is the type for the genus Cytinus. The binomial has been conserved.
Cytinus visseri, commonly known as the Northern vampire cup, is a holoparasitic flowering plant in the family Cytinaceae. This flower favorably interacts with another plant, Helichrysum reflexum, that is a woody shrub in South Africa.
Daniel Lee Nickrent is an American botanist, working in plant evolutionary biology, including the subdisciplines of genomics, phylogenetics, systematics, population genetics, and taxonomy. A major focus has been parasitic flowering plants, particularly of the sandalwood order (Santalales). His interest in photographic documentation and photographic databases has led to several photographic databases including Parasitic Plant Connection, Phytoimages, Plant Checklist for the Rocky Mountain National Park, and Plant Checklist for the Crab Orchard National Wildlife Refuge.
Romina Vidal-Russell is an Argentinean botanist who works in the areas of phytogeography, phylogeny, and parasitic plants, and on which she has written extensively. Her papers on the phylogeny of parasitic plants are cited on the APG website, and elsewhere and her collaborations are international. She currently works at the National University of Comahue in Argentina. She earned a Ph.D at SIUC with Daniel L. Nickrent as supervisor.
Cytinus sanguineus is a species of parasitic plant in the family Cytinaceae.
