Thalia is a genus of flowering plants in the Marantaceae (prayer plant and arrowroot) family found mainly in aquatic, marshy and riparian zones in Eastern, Central and Western Africa—as far south as Zimbabwe—and the Americas, from Illinois in the north, through northern Argentina in the southern part of its range.[1] These plants can (and prefer to) grow with their roots and rhizomes fully submerged and their foliage growing emersed from the water's surface. They thrive in floodplains, vernal pools and other seasonally-inundated areas, as well. Alligator-flag is a common name for plants in this genus.[2] The generic name is in honor of Johannes Thal (1542–1583), a German doctor who wrote A Flora of the Harz Mountains.
