Lentibulariaceae, the bladderwort family, 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.
Nepenthes kampotiana is a tropical pitcher plant native to southern Cambodia, eastern Thailand, and at least southern coastal Vietnam. It has an altitudinal distribution of 0–600 m above sea level. The specific epithet kampotiana refers to the Cambodian city of Kampot, close to which the first specimens of this species were collected.
Utricularia gibba, commonly known as the humped or floating bladderwort, is a small, mat-forming species of carnivorous aquatic bladderwort. It is found on all continents except Antarctica.
Utricularia beaugleholei is a terrestrial carnivorous plant that belongs to the genus Utricularia. Its distribution ranges from southeastern South Australia through central and western Victoria into New South Wales, where it has been collected from the southern tablelands and southwest slopes.
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 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 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 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.
Utricularia calycifida is a small to medium-sized terrestrial perennial carnivorous plant that belongs to the genus Utricularia. U. calycifida is endemic to northern South America and can be found in Brazil, Guyana, Suriname, and Venezuela.
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 carnivorous plant that belongs to the genus Utricularia. U. cornuta is endemic to North America and can be found in the Bahamas, Cuba, Canada, and the United States. It 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 sect. Nigrescentes is a section in the genus Utricularia. The three species in this section are small terrestrial carnivorous plants native to tropical Africa, Asia, and Australia. Daniel Oliver originally validly described and published this section in 1859, but did not specify the rank used by the group. Sadashi Komiya revised the section in 1973. Peter Taylor, in his 1989 taxonomic monograph on the genus, placed this section within subgenus Utricularia. More recent phylogenetic data and revisions have reinstated subgenus Bivalvaria and have placed this section within it.
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.
Utricularia sect. Phyllaria is a section in the genus Utricularia. The sixteen species in this section are small or very small lithophytic or epiphytic carnivorous plants native to the mountains of Asia, ranging from India to China and New Guinea. One species, Utricularia striatula, is an exception and is widespread in much of the Old World tropics. Wilhelm Sulpiz Kurz originally described and published this section as Utricularia subg. Phyllaria in 1874. Franciszek Kamieński reviewed the genus in 1891 and reduced Kunz's subgenus to a section. Later botanists, including Peter Taylor, agreed with Kamieński's assessment. In Taylor's 1986 revision of the genus, he placed this section in subgenus Utricularia. Later molecular data resulted in the revision of Taylor's treatment, reinstating subgenus Bivalvaria and placing this section within it.
There are fourteen species of carnivorous plants occurring in New Zealand, and four species that have been known to occur in the past.
Utricularia cornigera is a large perennial carnivorous plant that belongs to the genus Utricularia. U. cornigera was described in 2009 by Miloslav Studnička based on his study of the variation in cultivated plants labeled Utricularia reniformis and apparent different geographic ranges. U. cornigera is found on Serra dos Órgãos in south-eastern Brazil and as of the new species' description, was not found in the presence of U. reniformis. Utricularia cornigera has been grown in cultivation under the name U. reniformis and with the cultivar name 'Big Sister'. It differs from U. reniformis by having 6-8 primordial leaves emerging from the seed during germination with a float and whorl of leaves. Utricularia cornigera also produces two distinct types of bladder traps that are dimorphic and it generally has larger leaves.
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.
Australia has one of the world's richest carnivorous plant floras, with around 187 recognised species from 6 genera.
The North American Continent is home to a wide variety of carnivorous plant species. Species from seven genera are native to the continent, and three of these genera are found nowhere else on the planet.
