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 tenuissima is a small, annual, terrestrial carnivorous plant that belongs to the genus Utricularia and is the only member of Utricularia sect. Martinia. U. tenuissima is endemic to South America, where it can be found in Brazil, Colombia, Guyana, Suriname, Trinidad, and Venezuela. It grows as a terrestrial plant in wet, open savanna usually in sand at altitudes from sea level to 2,100 m (6,890 ft). It was originally published and described by Thomas Gaskell Tutin in 1934 and placed in its own section, Martinia, in 1986 by Peter Taylor.

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.

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.

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.
Utricularia parthenopipes is a small annual carnivorous plant that belongs to the genus Utricularia. U. parthenopipes is endemic to the Brazilian state of Bahia. It grows as a terrestrial plant in damp, sandy soils over sandstone rocks at altitudes from 500 m (1,640 ft) to 1,500 m (4,921 ft). It flowers between January and June in its native range.

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.

U. meyeri grows as a terrestrial plant in bogs and seasonally flooded swamps and grasslands at altitudes from 400 m (1,312 ft) to around 600 m (1,969 ft). It was originally described by Robert Knud Friedrich Pilger in 1901 and later reduced to synonymy under U. erectiflora by Peter Taylor in 1967. He later reevaluated his decision on the basis of scanning electron microscope images of the seed of the two species.
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.

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.

U. kumaonensis grows as a lithophyte, epiphyte, or terrestrial plant on mossy rocks or in bog grasslands at altitudes from 2,250 m (7,382 ft) to 4,200 m (13,780 ft). It was originally described by Daniel Oliver in 1859, although Peter Taylor asserted in his 1989 monograph that Michael Pakenham Edgeworth's 1847 description of Diurospermum album is U. kumaonensis. It is very similar to U. multicaulis.
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).

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).
