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.
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 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.

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 graminifolia is a small perennial carnivorous plant that belongs to the genus Utricularia. It is native to Asia, where it can be found in Burma, China, India, Sri Lanka, and Thailand.
