Utricularia humboldtii is a large perennial carnivorous plant that belongs to the genus Utricularia. Peter Taylor lists it as either an "aquatic-epiphyte", a subaquatic or a terrestrial species. U. humboldtii is endemic to South America, where it is found in Brazil, Guyana, and Venezuela. It was originally published and described by Robert Hermann Schomburgk in 1840. It is usually found growing in the water-filled leaf axils of some species of bromeliad, including Brocchinia micrantha, B. tatei, and B. reducta and also plants in the genus Orectanthe. It also grows as an epiphyte on tree trunks or as a subaquatic or terrestrial species in shallow water or wet soil in open savanna. It is found mostly between altitudes of 1,200 m (3,937 ft) and 2,500 m (8,202 ft), though it has been found at altitudes as low as 300 m (984 ft). It has been collected in flower throughout every month of the year.
Utricularia unifolia is a medium-sized perennial carnivorous plant that belongs to the genus Utricularia. U. unifolia is native to Central America and western South America. It was originally published and described by Hipólito Ruiz López and José Antonio Pavón Jiménez in 1797 and later considered a synonym of Utricularia alpina until Peter Taylor's 1989 monograph on the genus where he restored the species as distinct from U. alpina. It grows as a terrestrial or epiphytic plant on moss-covered trees, rocks, or banks in cloud forests at altitudes between 2,000 m (6,562 ft) and 3,000 m (9,843 ft). U. unifolia usually produces only one leaf, which is where the species epithet "unifolia" is derived from.
Utricularia podadena is a small, probably perennial, terrestrial carnivorous plant that belongs to the genus Utricularia and is the only member of Utricularia sect. Candollea. U. podadena is endemic to Malawi and Mozambique, being known only from the type location in Malawi and from one other collection in Mozambique. As of Peter Taylor's 1989 monograph on the genus, more recent efforts to locate this species have failed. It was originally published and described by Taylor in 1964 and placed in its own section, Candollea, in 1986. It grows as a terrestrial plant in marshy grasslands in the presence of Loudetia species at altitudes of around 1,000 m (3,281 ft). It flowers in July. It is a very distinct plant in the genus with the long stipitate glandular trichomes covering the flower. Its affinities within the genus are not clear.
Utricularia minutissima is a small or very small terrestrial carnivorous plant that belongs to the genus Utricularia. U. minutissima is native to Asia and Australia. Among the islands of Southeast Asia, it is found on Borneo, New Guinea, and Sumatra.
Utricularia mannii is a small, perennial, epiphytic carnivorous plant that belongs to the genus Utricularia and is the only member of Utricularia sect. Chelidon. U. mannii is endemic to tropical Africa, particularly the islands in the Gulf of Guinea and the adjacent mainland. It grows as an epiphytic plant on mossy tree trunks in rain forests at altitudes from 500 m (1,640 ft) to 2,100 m (6,890 ft). It has been collected in flower between April and November. It was originally published and described by Daniel Oliver in 1865 and placed in its own section, Chelidon, in 1986 by Peter Taylor.

U. appendiculata is endemic to Africa, where it can be found in Burundi, Cameroon, the Central African Republic, the Democratic Republic of the Congo, Gabon, Madagascar, Malawi, Mozambique, Tanzania, Uganda, and Zimbabwe. It grows as a terrestrial plant in wet Sphagnum bogs, damp sandy savannas, or in peaty marshes at altitudes from 1,500 m (4,921 ft) to 1,860 m (6,102 ft), but as low as 700 m (2,297 ft) in the Central African Republic. It flowers mostly in the wet season. It was originally published and described by Eileen Adelaide Bruce in 1933 and was placed in its own section, Oliveria, in 1986 by Peter Taylor.
Utricularia viscosa is a small to medium sized perennial, terrestrial or subaquatic carnivorous plant that belongs to the genus Utricularia and is the only member of Utricularia sect. Sprucea. U. viscosa is native to Central America and South America. It grows as a terrestrial or subaquatic plant in wet sandy savannas at lower altitudes but as high as 900 m (2,953 ft) in Guyana. It was originally named by Richard Spruce and formally described by Daniel Oliver in 1860. In 1986, Peter Taylor placed this species in its own section, Sprucea, which was named in honor of Richard Spruce.

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.

It grows as a rheophyte on rocks in shallow running water at altitudes from 360 m (1,181 ft) to 690 m (2,264 ft). It was originally described and published by Peter Taylor in 1963. It is distinguished from the other species in the section, U. rigida, by having four lower lip corolla lobes as opposed to U. rigida's two.

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 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 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 pulchra is a small, probably annual, carnivorous plant that belongs to the genus Utricularia. It is endemic to New Guinea. U. pulchra grows as a lithophyte or terrestrial plant among mosses in wet sand or rocks and on wet cliffs at altitudes from 2,250 m (7,382 ft) to 3,100 m (10,171 ft). It was originally described by Peter Taylor in 1977.
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.
