Question: What are both Calliandra and Thalia?

full_context: Document 1: Calliandra erythrocephala: Calliandra erythrocephala is a species of flowering plants of the genus "Calliandra" in the Fabaceae family, endemic to southwestern Mexico. It is a small tree with bright red flowers. Like other members of the genus "Calliandra", the filaments of the stamens are long and colourful, in this case about 4.5 – long. The species was first scientifically described in 1988.
Document 2: Alternanthera philoxeroides: Alternanthera philoxeroides, commonly referred to as alligator weed, is a native species to the temperate regions of South America, which includes Argentina, Brazil, Paraguay and Uruguay. Argentina alone, hosts around 27 species that fall within the range of the genus Alternanthera. Its geographic range once used to cover only the Parana River region of South America, but it has since expanded to cover over 30 countries, such as the United States, New Zealand, China and many more. This invasive species is believed to have been accidentally introduced to these non-native regions through sediments trapped/attached to tanks and cargo of ships travelling from South America to these various areas.
Document 3: Salvinia auriculata: Salvinia auriculata is a species of plant in the Salviniaceae known by the common names eared watermoss, African payal, and butterfly fern. It is native to the Americas from Mexico south to Argentina and Chile. It is cultivated as an ornamental plant and it has become naturalized in the wild in some places.
Document 4: Thonningia: Thonningia is a monotypic genus of flowering plants in the family Balanophoraceae containing the single species Thonningia sanguinea. It is distributed throughout much of southern and western Africa, particularly the tropical regions. Common names for the plant include ground pineapple. A familiar plant to humans, it has an extremely long list of common names in many African languages. Many names are inspired by the resemblance of the plant's inflorescence to a pineapple or palm tree. Some of the names can be translated as pineapple of the bush (from Anyi), duiker's kolanut (from Igala), and crown of the ground (from Yoruba).

Document 9: Echinodorus grisebachii: Echinodorus grisebachii or Echinodorus amazonicus is commonly known as Amazon sword plant, although other plants are also known under this common name.

Document 10: Thalia dealbata: Thalia dealbata, the powdery alligator-flag, hardy canna, or powdery thalia, is an aquatic plant in the family Marantaceae, native to swamps, ponds and other wetlands in the southern and central United States. Its range includes much of Coastal Plains and the lower Mississippi Valley (States of South Carolina, Georgia, Alabama, Mississippi, Louisiana, Texas, Oklahoma, Arkansas, Missouri, Illinois and Kentucky). The plant has been grown as an aquatic ornamental because of the pretty violet flowers, and in cultivation has been proved hardy as far north as Philadelphia (Pennsylvania) and Vancouver (British Columbia).
Document 11: Salvinia: Salvinia, a genus in the family Salviniaceae, is a floating fern named in honor of Anton Maria Salvini, a 17th-century Italian scientist. Watermoss is a common name for "Salvinia". The genus was published in 1754 by Jean-François Séguier, in his description of the plants found round Verona, "Plantae Veronenses" Twelve species are recognized, at least three of which ("S. molesta", "S. herzogii", and "S. minima") are believed to be hybrids, in part because their sporangia are found to be empty.
Document 12: Thalia (plant): Thalia is a genus of six currently recognized species found in aquatic or marshy habitats, ranging in Africa from Senegal to Sudan to Zimbabwe, and in the Americas from Illinois to Argentina. Alligator-flag is a common name for plants in this genus. The generic name is in honor of Johannes Thal (1542–1583), a German doctor who wrote a Flora of the Harz Mountains.
Document 13: Calliandra calothyrsus: Calliandra calothyrsus is a small leguminous tree or large shrub in the Fabaceae family. It is native to the tropics of Central America where its typical habitat is wet tropical forests or seasonally dry forests with a dry season of four to seven months, when it may become deciduous. This tree grows to about 6 m and has pinnate compound leaves and flowers with a boss of prominent reddish-purple stamens. It is not very drought-tolerant and the above-ground parts are short-lived but the roots regularly resprout.
Document 14: Justicia (plant): Justicia is a genus of flowering plants in the family Acanthaceae. There are 658 species with a further 611 species as yet unresolved by Kew. They are native to tropical to warm temperate regions of the Americas, India and Africa. Common names include water-willow and shrimp plant, the latter from the inflorescences, which resemble a shrimp in some species. The generic name honours Scottish horticulturist James Justice (1698–1763). They are closely related to "Pachystachys".
Document 15: Calliandra: Calliandra is a genus of flowering plants in the pea family, Fabaceae, in the mimosoid clade of the subfamily Caesalpinioideae. It contains about 140 species that are native to tropical and subtropical regions of the Americas.
