Utricularia, commonly and collectively called the bladderworts, is a genus of carnivorous plants consisting of approximately 233 species (precise counts differ based on classification opinions; one recent publication lists 215 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 cornigera is a large perennial carnivorous plant that belongs to the genus "Utricularia".
 "U. cornigera" was described in 2009 by Miloslav Studnička based on his study of the variation in cultivated plants labeled "Utricularia reniformis" and apparent different geographic ranges.
 "U. cornigera" is found on Serra dos Órgãos in south-eastern Brazil and as of the new species' description, was not found in the presence of "U. reniformis".
 "Utricularia cornigera" has been grown in cultivation under the name "U. reniformis" and with the cultivar name 'Big Sister'.
 It differs from "U. reniformis" by having 6-8 primordial leaves emerging from the seed during germination with a float and whorl of leaves.
 "Utricularia cornigera" also produces two distinct types of bladder traps that are dimorphic and it generally has larger leaves.
Alphitonia is a genus of arborescent flowering plants comprising about 20 species, constituting part of the buckthorn family (Rhamnaceae) of the rosid eudicots.
 They occur in tropical regions of Southeast Asia, Oceania and Polynesia.
 These are large trees or shrubs.
 In Australia, they are often called "ash trees" or "sarsaparilla trees".
 This is rather misleading however; among the flowering plants, "Alphitonia" is not closely related to the true ash trees ("Fraxinus" of the asterids), and barely at all to the monocot sarsaparilla vines ("Smilax").
Utricularia" sect.
 "Aranella is a section in the genus "Utricularia".
 The ten species in this section are small terrestrial carnivorous plants native to tropical South America with one species also extending into tropical Africa.
 John Hendley Barnhart originally described and published this section in 1913 as a separate genus, "Aranella".
 Sadashi Komiya revised the genus "Utricularia" in a 1973 taxonomic review and placed Barnhart's genus at the rank of subgenus within "Utricularia".
 Peter Taylor then published his taxonomic monograph of "Utricularia" in 1986 in which he reduced Komiya's subgenus to the rank of section, placing it within subgenus "Utricularia".
 More recent phylogenetic data and revisions have reinstated subgenus "Bivalvaria" and have placed this section within it.
Utricularia" sect.
 "Orchidioides is a section in the genus "Utricularia".
 The species in this section are small or medium-sized terrestrial or epiphytic carnivorous plants native to Central and South America.
 Alphonse Pyrame de Candolle originally published this section in 1844.
 In 1916, John Hendley Barnhart moved the section to its own genus, "Orchyllium", recognizing that the species in this section are distinct.
 Several other botanists, including Henry Gleason, considered the treatment of these species in the genus "Orchyllium" valid and moved other species from "Utricularia" to "Orchyllium".
 Ultimately the species were all reunited under "Utricularia".
Utricularia" sect.
 "Calpidisca is a section in the genus "Utricularia".
 The ten species in this section are small terrestrial carnivorous plants native to Africa with one species extending its range into Mexico and another that extends into Asia as far as India.
 John Hendley Barnhart originally described and published this section in 1916 as a separate genus, "Calpidisca".
 Sadashi Komiya revised the genus "Utricularia" in a 1973 taxonomic review and placed Barnhart's genus at the rank of section within "Utricularia".
 Peter Taylor then published his taxonomic monograph of "Utricularia" in 1986 in which he placed Komiya's section within subgenus "Utricularia".
 More recent phylogenetic data and revisions have reinstated subgenus "Bivalvaria" and have placed this section within it.
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" sect.
 "Kamienskia is a section in the genus "Utricularia".
 The two species in this section are very small bryophilous lithophytic carnivorous plants. Peter Taylor originally described and published the section and its single species, "Utricularia peranomala", in 1986.
 In 2007, Guang Wan Hu described "Utricularia mangshanensis" and placed it in this section.
 Both species are endemic to China.
Utricularia" sect.
 "Choristothecae is a section in the genus "Utricularia".
 The two species in this section are very small rheophytic carnivorous plants that were formally included in section "Avesicaria" but were reassigned to their own section by Peter Taylor in 1989.
 He had included them in section "Avesicaria" largely because of the similar habit of the species, but the unique pollen morphology, dissimilar internal trap glands, and the anthers led Taylor to move these two species to section "Choristothecae".
 Both species are endemic to South America, with "Utricularia determannii" only known from Suriname and "Utricularia choristotheca" located in French Guiana and Suriname.
Utricularia" sect.
 "Setiscapella is a section in the genus "Utricularia" that contains small or medium-sized terrestrial or subaquatic species.
 Most plants in this section are endemic to Central and South America with the exceptions of "Utricularia stanfieldii", which is endemic to Africa, and "Utricularia subulata" which is almost pantropical.
 It was first described by John Hendley Barnhart in 1916 at the rank of genus.
 In 1973, Sadashi Komiya reduced the genus to a subgenus of the genus "Utricularia".
 In his 1986 monograph on the genus, Peter Taylor reorganized the genus and reduced this to the rank of section.
