Utricularia quinquedentata is an annual, terrestrial carnivorous plant that belongs to the genus Utricularia. Its distribution ranges across northern Australia from Western Australia to northern Queensland and south to Brisbane. It was first identified by Ferdinand von Mueller as possibly a new species or variety in the early 1890s, noting it as "U. albiflora or a closely allied species." Mueller labeled one herbarium sheet as Utricularia albiflora var. quinquedentata. Without a valid description, according to the rules of botanical nomenclature, however, the epithet quinquedentata was not recognized until Peter Taylor validly published the species in 1986.
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 spruceana is a small, affixed subaquatic or terrestrial carnivorous plant that belongs to the genus Utricularia. It is native to South America with distributions in Brazil and Venezuela. Peter Taylor had reduced this species to a synonym under U. resupinata in 1967 because the only difference between the specimens he examined at the time was the smaller size of U. spruceana. Other collections were made of both species after that publication and Taylor reestablished U. spruceana based on these collections that displayed distinct differences between the species.
Philcoxia is a genus of seven rare plant species in the Plantaginaceae that are endemic to Brazil and resemble terrestrial species of the genus Utricularia. The genus, formally described in 2000, consists of the species P. bahiensis, P. goiasensis, P. minensis, P. tuberosa, P. rhizomatosa, P. maranhensis and P. courensis, each of the first three named for the Brazilian state to which it is endemic. The species are characterized by subterranean stems, peltate leaves at or below the soil surface, and five-lobed calyces. Their habitat has been reported as areas of white sand in the midst of cerrado vegetation at an elevation between 800 and 1450 m. Initial descriptions of the genus included suspicions that the plethora of stalked capitate glands on the upper surfaces of leaves was an indication that these species may be carnivorous. A study published in 2007 tested P. minensis for protease activity, a typical test for the carnivorous syndrome, and could detect none. Later studies detected other digestive enzymes such as phosphatases and qualitatively assessed prey digestion and nutrient uptake, suggesting that it is a true carnivorous plant. The genus epithet honors David Philcox, a botanist at Kew Gardens who worked extensively in tropical Scrophulariaceae.
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 endresii is a medium-sized epiphytic, perennial carnivorous plant that belongs to the genus Utricularia. U. endresii is endemic to Central America and northwestern South America. It was originally published and described by the orchidologist Ludwig Reichenbach, who originally described it as a "Lentibulariaceous Orchid," a name which seems to have stuck for some time after its description in 1874. It was even cultivated in orchid houses. It is named in honor of A. R. Endres, the person who originally collected the first specimens sent to Reichenbach for description.
Utricularia pubescens is a small to medium-sized, probably annual, terrestrial or lithophytic carnivorous plant that belongs to the genus Utricularia and is the only member of Utricularia sect. Lloydia. U. pubescens is native to India, tropical Africa, and Central and South America. It was originally published and described by James Edward Smith in 1819 and placed in its own section, Lloydia, by Peter Taylor in 1986. It grows as a terrestrial or lithophytic plant in boggy grasslands in damp peaty soils at altitudes from sea level to 1,900 m (6,234 ft). This species possesses small peltate leaves, which are diagnostic for this species in the genus.
Utricularia microcalyx is a small to medium-sized annual carnivorous plant that belongs to the genus Utricularia. It is native to tropical Africa, where it can be found in the Democratic Republic of the Congo and Zambia. U. microcalyx grows as a terrestrial plant in damp, sandy or peaty soils in grasslands at altitudes from 1,200 m (3,937 ft) to 1,650 m (5,413 ft). It typically flowers between February and July. It was originally described and published by Peter Taylor in 1964 as a variety of U. welwitschii. Taylor elevated this variety to the species level in 1971.
Utricularia odontosepala is a small to medium-sized, probably annual, carnivorous plant that belongs to the genus Utricularia. It is native to tropical Africa, where it can be found in the Democratic Republic of the Congo, Malawi, and Zambia. U. odontosepala grows as a terrestrial plant in damp, peaty soils in grasslands at altitudes from 1,300 m (4,265 ft) to 2,200 m (7,218 ft). It typically flowers between April and September. It was originally described and published by Otto Stapf in 1912. Peter Taylor later reduced the species to a variety of U. welwitschii in 1964 but then reversed his decision and reestablished Stapf's original treatment of the species.
Utricularia welwitschii is a small to medium-sized, probably perennial, carnivorous plant that belongs to the genus Utricularia. It is endemic to tropical Africa, where it can be found in the Democratic Republic of the Congo, Madagascar, Malawi, South Africa, Tanzania, Zambia, and Zimbabwe. U. welwitschii grows as a terrestrial plant in sandy or peaty soils in marshy grasslands at altitudes from 1,000 m (3,281 ft) to 2,200 m (7,218 ft). It was originally described and published by Daniel Oliver in 1865. Taylor previously described two varieties of U. welwitschii, U. welwitschii var. odontosepala and U. welwitschii var. microcalyx, in 1964, but later elevated them to the rank of species as U. odontosepala and U. microcalyx, respectively. It is named in honor of Friedrich Welwitsch.
Utricularia delphinioides is a small to medium-sized, probably perennial, carnivorous plant that belongs to the genus Utricularia. It is endemic to Indochina and can be found in Cambodia, Laos, Thailand, and Vietnam. U. delphinioides grows as a terrestrial plant in swamps and rice fields, wet grasslands, or open pine forests at altitudes from near sea level to 1,300 m (4,265 ft). It was originally named by Clovis Thorel but formally described and published by François Pellegrin in 1920. A variety, U. delphinioides var. minor, was also described in 1920, but Peter Taylor reduced the variety to synonymy under U. delphinioides because he discovered a continuous range of sizes between the larger and smaller forms, size being the only distinctive characteristic in the 1920 description of the variety.
Utricularia letestui is a small, probably annual, carnivorous plant that belongs to the genus Utricularia. It is endemic to the Central African Republic and is only known from three collections. U. letestui grows as a terrestrial plant in seasonally flooded grasslands, usually at altitudes around 800 m (2,625 ft). It was originally described and published by Peter Taylor in 1989. It was named in honor of the French collector G. Le Testu.
Utricularia micropetala is a small annual carnivorous plant that belongs to the genus Utricularia. It is endemic to western tropical Africa and is found in the Central African Republic, Guinea, Nigeria, and Sierra Leone. U. micropetala grows as a terrestrial plant among wet rocks at altitudes up to 1,500 m (4,921 ft). It was originally described by James Edward Smith in 1819. It can be distinguished from all other species in section Oligocista by the large and inflated spur and very short lower corolla lip.
Utricularia pobeguinii is a small annual carnivorous plant that belongs to the genus Utricularia. It is endemic to Africa and is only found in the region around Kindia, Guinea. U. pobeguinii grows as a terrestrial plant in wet soils among sandstone at altitudes from 500 m (1,640 ft) to 1,000 m (3,281 ft). It was originally described by François Pellegrin in 1914, reduced to a variety of U. spiralis by Peter Taylor in 1963, and later elevated back to the species level by Taylor upon further investigation.
Utricularia recta is a small, probably annual carnivorous plant that belongs to the genus Utricularia. It is native to Bhutan, China, India, and Nepal. U. recta grows as a terrestrial plant in marshes and bogs from altitudes around 900 m (2,953 ft) to 4,000 m (13,123 ft). It was originally described as a variety of U. wallichiana by Daniel Oliver in 1859. It was later transferred to a variety of U. scandens by Krishnaier Subramanyam and Banerjee in 1968. Peter Taylor elevated the variety to the specific rank in 1986 upon further review of its morphological characteristics.
Utricularia scandens is a small, probably annual carnivorous plant that belongs to the genus Utricularia. It has a wide native distribution that includes Africa and Asia. U. scandens grows as a terrestrial plant in wet grasslands and bogs at lower altitudes around sea level up to 2,300 m (7,546 ft). It was originally described by Ludwig Benjamin in 1847. There is a significant amount of synonymy established for this species, in part because of its large distribution and variable morphology.
Utricularia steenisii is a small annual carnivorous plant that belongs to the genus Utricularia. It is endemic to Sumatra and is only known from higher elevations in Aceh. U. steenisii grows as a lithophyte or terrestrial plant among mosses in exposed or shady soils or on rocks at altitudes from 2,500 m (8,202 ft) to 3,200 m (10,499 ft). It was first collected in 1937 by Cornelis Gijsbert Gerrit Jan van Steenis, for whom the species is named. Peter Taylor misidentified a specimen of U. steenisii as U. salwinensis in 1977, but upon viewing further specimens, he realized the nature of this new species and formally described it in 1986.
Utricularia jackii is a terrestrial carnivorous plant that belongs to the genus Utricularia. It is endemic to Thailand. U. jackii grows among wet rocks at higher altitudes or sometimes in evergreen forests. It was first collected in 1927 and again in 1958. In his 1989 revision of his monograph, Peter Taylor discussed the specimen and identified it as potentially distinct, but never formally described it. John Adrian Naicker Parnell located the herbarium specimens in preparation for a review of Lentibulariaceae of Thailand and formally described it as a new species in 2005. Parnell named it in honor of his father, John "Jack" Thomas Mackie Parnell.
