Utricularia vulgaris is an aquatic species of bladderwort found in Asia and Europe. The plant is free-floating and does not put down roots. Stems can attain lengths of over one metre in a single growing season, but die back and form turions in winter. The leaves are finely pinnately divided, between one and eight centimetres long and carry many bladder-like traps. The yellow flowers are borne on stalks above the surface of the water between April and August. In eastern Asia and North America, its place is taken by the related species U. macrorhiza.
Utricularia amethystina, the Florida purple bladderwort, is a variable species of terrestrial bladderwort native to Bolivia, Brazil, Guyana, Peru, and south-west Florida. The small flowers can be purple, lilac, white, bluish, cream, or bright yellow, and are also highly variable in size and shape.
Utricularia gibba, commonly known as the humped bladderwort or floating bladderwort, is a small, mat-forming species of carnivorous aquatic bladderwort. It is found on all continents except Antarctica.
Utricularia pusilla, the tiny bladderwort, is an annual, terrestrial carnivorous plant that belongs to the genus Utricularia. Its distribution includes ranges in Mexico, the Caribbean and Central and South America: specifically in Argentina, Belize, Bolivia, Brazil, Colombia, Costa Rica, Cuba, Dominica, the Dominican Republic, Ecuador, French Guiana, Guatemala, Guyana, Honduras, Jamaica, Nicaragua, Panama, Paraguay, Peru, Puerto Rico, Surinam, Trinidad and Tobago, and Venezuela.
Utricularia subulata, the zigzag bladderwort, is a small annual, terrestrial carnivorous plant that belongs to the genus Utricularia. It is the most widely distributed species in the genus, being almost pantropical.
Utricularia biloba, the moth bladderwort, is a perennial, terrestrial or aquatic carnivorous plant that belongs to the genus Utricularia. It is endemic to Australia with a distribution along the coastal regions of New South Wales and Queensland.
Utricularia resupinata, popularly known as lavender bladderwort or northeastern bladderwort, is a small perennial subaquatic carnivorous plant that belongs to the genus Utricularia. It is native to eastern Canada, the United States, and Central America. This plant species has an interesting etymology, growth pattern, ecology, and research history. As a plant that is threatened or endangered in many of the States where it is found, it is a candidate for sound conservation efforts.
Utricularia breviscapa is a small to medium suspended aquatic carnivorous plant that belongs to the family Lentibulariaceae. It is probably an annual plant. Its native distribution includes the Antilles and South America.
Utricularia floridana, the Florida yellow bladderwort, is a large affixed aquatic carnivorous plant in the bladderwort genus within the bladderwort family). It is a perennial plant that is endemic to southeastern United States.
Utricularia macrorhiza, the common bladderwort, is a perennial suspended aquatic carnivorous plant that belongs to the genus Utricularia. U. macrorhiza is native to North America and eastern temperate Asia.
Utricularia minor, the lesser bladderwort, is a small species of perennial carnivorous plant in the family Lentibulariaceae. It is usually found affixed to the substrate but it can also survive suspended in a body of water. U. minor is a circumboreal species and is found in North America, Asia, and Europe.
Utricularia ochroleuca, the yellowishwhite bladderwort, pale bladderwort, or cream-flowered bladderwort, is a small, perennial carnivorous plant that belongs to the genus Utricularia. It is usually found affixed to the substrate. U. ochroleuca is a circumboreal species and is found in North America, Asia, and Europe.
Utricularia olivacea, the piedmont bladderwort, is a very small, annual suspended aquatic carnivorous plant that belongs to the genus Utricularia. Utricularia olivacea is native to Central America, South America, the West Indies, and the eastern United States.
Utricularia stygia, the arctic bladderwort or Northern bladderwort, is an affixed aquatic carnivorous plant that belongs to the genus Utricularia. U. stygia is native to northern Europe and North America. This species was originally published by Göran Thor in 1987 but the description was not in Latin and was therefore nomenclaturally invalid. Thor validly published the species a year later. The cited difference that separates U. stygia from U. ochroleuca is the shape of the tiny quadrifid glands inside the bladders, specifically at which angle the "arms" of these glands diverge from one another. Thor, when working on the Utricularia of Sweden noted that this distinction alone allowed for consistent species identification. Both Barry Rice and Peter Taylor have expressed concerns regarding how this method applies to other populations around the world.
Peter Geoffrey Taylor (1926–2011) was a British botanist who worked at Royal Botanic Gardens, Kew throughout his career in botany. Taylor was born in 1926 and joined the staff of the herbarium at Kew in 1948. He published his first new species, Utricularia pentadactyla, in 1954. In 1973, Taylor was appointed curator of the orchid division of the herbarium and, according to Kew, "under his direction, orchid taxonomy was revitalised and its horticultural contacts strengthened."
Utricularia cornuta, the horned bladderwort, is a small to medium-sized, probably perennial species of carnivorous plant in the family Lentibulariaceae. It is endemic to North America and can be found in the Bahamas, Cuba, Canada, and the United States. Utricularia cornuta grows as a terrestrial or subaquatic plant in marshes, swamps, and pools in shallow waters, mostly at lower altitudes. It was originally described and published by André Michaux in 1803.
Utricularia lateriflora, the small bladderwort, is a small to medium-sized perennial carnivorous plant that belongs to the genus Utricularia. U. lateriflora is endemic to Australia and can be found in New South Wales, Queensland, South Australia, Tasmania, and Victoria. It grows as a terrestrial plant in sandy or peaty soils in heathland at lower altitudes. It was originally described and published by Robert Brown in 1810.
Utricularia andongensis is a small, probably perennial, carnivorous plant that belongs to the family Lentibulariaceae. It is endemic to tropical Africa, where it can be found in Angola, Cameroon, the Central African Republic, the Democratic Republic of the Congo, Gabon, Guinea, Liberia, Nigeria, Sierra Leone, Sudan, Tanzania, Togo, Uganda, and Zambia. U. andongensis grows as a terrestrial or lithophytic plant on wet, bare rocks or among mosses in grasslands at altitudes from 240 m (787 ft) to 1,800 m (5,906 ft). It was originally named by Friedrich Welwitsch but formally described and published by William Philip Hiern in 1900.
Griffinia is a genus of Brazilian plants in the Amaryllis family, subfamily Amaryllidoideae. It includes 23 known species which are endemic to Brazil. The most closely related genus to it is the monotypic Worsleya.
The Genus Utricularia: A Taxonomic Monograph is a monograph by Peter Taylor on the carnivorous plant genus Utricularia, the bladderworts. It was published in 1989 by Her Majesty's Stationery Office (HMSO) as the fourteenth entry in the Kew Bulletin Additional Series. It was reprinted for The Royal Botanic Gardens, Kew in 1994.
