Question: Between Thalia and Calibanus, which genus has more species?

full_context: Document 1: 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 3: 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).

The aquatic plant is cultivated for and used in ponds and artificial aquatic habitats. It is native to Cuba, Central America, and South America as far south as Brazil and Bolivia.
Document 5: 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.

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 10: 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.

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.
