Between Thalia and Calibanus, which genus has more species?
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.
Ceiba Ceiba is a genus of trees in the Malvaceace family, native to tropical and subtropical areas of the Americas (from Mexico and the Caribbean to N Argentina) and tropical West Africa. Some species can grow to 70 m tall or more, with a straight, largely branchless trunk that culminates in a huge, spreading canopy, and buttress roots that can be taller than a grown person. The best-known, and most widely cultivated, species is Kapok, "Ceiba pentandra", one of several trees called kapok.
