Question: Are both Xanthosoma and Tabebuia a genus of flowering plants in the same family?
Context: Chloranthaceae is a family of flowering plants (angiosperms), the only family in the order Chloranthales.  It is not closely related to any other family of flowering plants, and is among the early-diverging lineages in the angiosperms.  They are woody or weakly woody plants occurring in Southeast Asia, the Pacific, Madagascar, Central and South America, and the West Indies.  The family consists of four extant genera, totalling about 77 known species according to Christenhusz and Byng in 2016.  Some species are used in traditional medicine.  The type genus is "Chloranthus". Apiaceae or Umbelliferae, is a family of mostly aromatic flowering plants named after the type genus "Apium" and commonly known as the celery, carrot or parsley family.  It is the 16th-largest family of flowering plants, with more than 3,700 species in 434 genera including such well-known and economically important plants such as angelica, anise, asafoetida, caraway, carrot, celery, chervil, coriander, cumin, dill, fennel, hemlock, lovage, cow parsley, parsley, parsnip, sea holly, giant hogweed and silphium (a plant whose identity is unclear and which may be extinct). Xanthosoma is a genus of flowering plants in the arum family, Araceae.  The genus is native to tropical America but widely cultivated and naturalized in other tropical regions.  Several are grown for their starchy corms, an important food staple of tropical regions, known variously as "malanga", "otoy", "otoe", cocoyam (or new cocoyam), "tannia", "tannier", "yautía", "macabo", "ocumo", "macal", "taioba", "dasheen", "quequisque", "ʻ ape" and (in Papua New Guinea) as Singapore taro ("taro kongkong").  Many other species (including especially "X. roseum") are used as ornamental plants, and in popular horticultural literature are known as ‘ape or elephant ear (from the purported resemblance of the leaf to an elephant's ear), although the latter name is sometimes also applied to members with similar appearance and uses in the closely related genera "Caladium", "Colocasia" (i.e., taro), and "Alocasia". Tabebuia is a genus of flowering plants in the family Bignoniaceae.  The common name "roble" is sometimes found in English.  "Tabebuias" have been called "trumpet trees", but this name is usually applied to other trees and has become a source of confusion and misidentification. Caladium is a genus of flowering plants in the family Araceae.  They are often known by the common name elephant ear (which they share with the closely related genera "Alocasia", "Colocasia", and "Xanthosoma"), Heart of Jesus, and Angel Wings.  There are over 1000 named cultivars of "Caladium bicolor" from the original South American plant. Colocasia is a genus of flowering plants in the family Araceae, native to southeastern Asia and the Indian subcontinent.  Some species are widely cultivated and naturalized in other tropical and subtropical regions.  Common names include tarul, karkala ko ganu, elephant-ear, taro, cocoyam, dasheen, chembu, champadhumpa, shavige gadde, and eddoe.  Elephant-ear and cocoyam are also used for some other large-leaved genera in the Araceae, notably "Xanthosoma" and "Caladium".  The generic name is derived from the ancient Greek word "kolokasion", which in the Greek botanist Dioscorides (1st century AD) meant the edible roots of both "Colocasia esculenta" and "Nelumbo nucifera".  It is thought that the edible roots of "Colocasia esculenta" have been cultivated in Asia for more than ten thousand years.  The species "Colocasia esculenta" is an invasive species in wetlands along the American Gulf coast, where it threatens to displace native wetland plants. Austrobaileyales is an order of flowering plants, consisting of about 100 species of woody plants growing as trees, shrubs and lianas.  Perhaps the most familiar species is "Illicium verum", from which comes the spice star anise.  The order belongs to the group of basal angiosperms, the ANA grade, which diverged earlier from the remaining flowering plants, and, as such, it is the extant group after the Amborellales and Nymphaeales, that is sister to all remaining extant angiosperms outside of the ANA grade.  The order includes just three families of flowering plants, the Austrobaileyaceae, a monotypic family containing the sole genus, "Austrobaileya scandens", a woody liana, the Schisandraceae, a family of trees, shrubs, or lianas containing essential oils, and the Trimeniaceae, essential oil-bearing trees and lianas. Gnetophyta is a division of plants, grouped within the gymnosperms (which also includes conifers, cycads, and ginkgos), that consists of some 70 species across the three relict genera: "Gnetum" (family Gnetaceae), "Welwitschia" (family Welwitschiaceae), and "Ephedra" (family Ephedraceae).  Fossilized pollen attributed to a close relative of "Ephedra" has been dated as far back as the Early Cretaceous.  Though diverse and dominant in the Tertiary, only three families, each containing a single genus, are still alive today.  The primary difference between gnetophytes and other gymnosperms is the presence of vessel elements, a system of conduits that transport water within the plant, similar to those found in flowering plants. Because of this, gnetophytes were once thought to be the closest gymnosperm relatives to flowering plants, but more recent molecular studies have largely disproven this hypothesis. Ekmanianthe is a genus of flowering plants in the family Bignoniaceae.  It is most closely related to "Tabebuia" and has sometimes been included within it.  It consists of two species of trees, neither of which is especially common in any part of its range. " Ekmanianthe longiflora" grows to 18 m in height and is native to Haiti and the rocky uplands of central Cuba. " Ekmanianthe actinophylla" is a smaller tree, to 10 m in height, and it occurs in western Cuba where it is known as "roble caimán", for the resemblance of its trunk bark to the hide of a caiman.  "Roble" is a Spanish name that is also applied to "Tabebuia".  Neither of the species of "Ekmanianthe" is known in cultivation.  The type species for "Ekmanianthe" is "E. longiflora".  The wood of "Ekmanianthe" has been variously described as "soft" or as "very hard, heavy, and strong".  It is probably useful, but the tree is rarely recognized by lumberjacks. Psychotria is a genus of flowering plants in the Rubiaceae family.  It contains around 1,850 species and is therefore one of the largest genera of flowering plants.  The genus has a pantropical distribution and members of the genus are small understorey trees in tropical forests.  Some species are endangered or facing extinction due to deforestation, especially species of central Africa and the Pacific.
