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 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 sect. Utricularia is a section in the genus Utricularia. The species in this section are suspended or affixed aquatic carnivorous plants.
Utricularia aurea, the golden bladderwort, is a medium- to large-sized suspended aquatic carnivorous plant that belongs to the genus Utricularia. It is the most common and widespread suspended aquatic species in Asia. Its native distribution ranges from India to Japan and Australia.
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 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.
Utricularia stellaris is a medium to large sized suspended aquatic carnivorous plant that belongs to the genus Utricularia. U. stellaris is native to Africa, tropical Asia, and northern Australia.
Utricularia striata, the striped bladderwort, is a medium-sized affixed subaquatic carnivorous plant that belongs to the genus Utricularia. U. striata is endemic to the eastern coastal plains of the United States.
Fulvous is a colour, sometimes described as dull orange, brownish-yellow or tawny; it can also be likened to a variation of buff, beige or butterscotch. As an adjective it is used in the names of many species of birds, and occasionally other animals, to describe their appearance. It is also used as in mycology to describe fungi with greater colour specificity, specifically the pigmentation of the surface cuticle, the broken flesh and the spores en masse.
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 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. 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 bifida is a small annual carnivorous plant that belongs to the genus Utricularia. It is native to Asia and Oceania and can be found in Australia, Bangladesh, Burma, Cambodia, China, Guam, India, Indonesia, Japan, Korea, Laos, Malaysia, Nepal, New Guinea, Palau, the Philippines, Sri Lanka, Thailand, and Vietnam. U. bifida grows as a terrestrial plant in damp soils and in rice fields. It was originally described and published by Carl Linnaeus in 1753.
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.
Utricularia striatula is a small carnivorous plant that belongs to the genus Utricularia. It is widespread from tropical Africa to New Guinea. U. striatula grows as a lithophyte or epiphyte on wet rocks or tree trunks at altitudes from near sea level to 3,300 m (10,827 ft). It was originally described by James Edward Smith in 1819.
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.
