Lentibulariaceae is a family of carnivorous plants containing three genera: Genlisea, the corkscrew plants; Pinguicula, the butterworts; and Utricularia, the bladderworts.
Utricularia, commonly and collectively called the bladderworts, is a genus of carnivorous plants consisting of approximately 233 species. They occur in fresh water and wet soil as terrestrial or aquatic species across every continent except Antarctica. Utricularia are cultivated for their flowers, which are often compared with those of snapdragons and orchids, especially amongst carnivorous plant enthusiasts.
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 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 inflata, commonly known as the swollen bladderwort, inflated bladderwort, or large floating bladderwort, is a large suspended aquatic carnivorous plant that belongs to the genus Utricularia. It is a perennial that is native to the southeastern coastal plains of the United States. It has often been confused with U. radiata, which is similar but smaller than U. inflata. Since 1980, U. inflata has been reported to exist in locations beyond its traditional range, such as the Adirondack Mountains in New York, southeastern Massachusetts, and in Washington State. Studies on the populations in the Adirondacks suggest that an introduction of U. inflata to a location where it naturalizes can lead to altered sediment chemistry by reducing the net primary productivity of native species. It is also listed by the state of Washington as a problematic species because of the dense mat-forming habit of this aquatic Utricularia. It is one of the few carnivorous plants that can be invasive.
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 intermedia, the flatleaf bladderwort or intermediate bladderwort is a small, perennial carnivorous plant that belongs to the genus Utricularia. It is usually found affixed to the substrate but it can also survive suspended in a body of water. U. intermedia 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 radiata, the little floating bladderwort, is a medium-sized suspended aquatic carnivorous plant that belongs to the genus Utricularia. U. radiata is endemic to North America.
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 subg. Bivalvaria is a subgenus in the genus Utricularia. It was originally described by Wilhelm Sulpiz Kurz in 1874. In Peter Taylor's 1989 monograph on the genus, he reduced the subgenus to synonym under section Oligocista, a decision that was later reversed in the light of molecular phylogenetic studies and the subgenus was restored.
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 juncea, the southern bladderwort, is a small to medium-sized, probably perennial carnivorous plant that belongs to the genus Utricularia. U. juncea is native to Central, South, and North America. It grows as a terrestrial plant in marshes, swamps, and pools in shallow waters, mostly at lower altitudes. It was originally described and published by Martin Vahl in 1804.
Utricularia sect. Oligocista is the largest section in the genus Utricularia. The 42 species in this section are small to medium-sized terrestrial carnivorous plants native throughout the tropics, with six species in the Americas, ten in Africa, five in Australia, and the remainder in Asia, with 17 mostly native to peninsular India. Alphonse Pyrame de Candolle originally described and published this section in 1844. Peter Taylor published his taxonomic monograph of Utricularia in 1986, in which he placed this section within subgenus Utricularia. More recent phylogenetic data and revisions have reinstated subgenus Bivalvaria and have placed this section within it.
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.
