Brasenites kansense was a species of aquatic plant, which occurred in the early Cretaceous period of the United States of America. [1]
Brasenites kansense has suborbicular to orbicular, petiolate, peltate leaves with entire margins. The orbicular leaves are 6–8 cm wide, and the suborbicular leaves are 7.5-12.2 cm long, and 6–10.1 cm wide. The leaf venation is actinodromous. [1]
It was published by Hongshan Wang and David L. Dilcher in 2006. [1]
The type specimen was collected in Barton County, Kansas, USA. [1]
The generic name Brasenites expresses an association to the genus Brasenia . The specific epithet kansense refers to Kansas, USA. [1]
Ginkgoales are a gymnosperm order containing only one extant species: Ginkgo biloba, the ginkgo tree. It is monotypic, within the class Ginkgoopsida, which itself is monotypic within the division Ginkgophytaghing-KOF-it-ə. The order includes five families, of which only Ginkgoaceae remains extant.
Ephedraceae is a family of gymnosperms belonging to Gnetophyta, it contains only a single extant genus, Ephedra, as well as a number of extinct genera from the Early Cretaceous.
Gnetophyta is a division of plants, grouped within the gymnosperms, that consists of some 70 species across the three relict genera: Gnetum, Welwitschia, and Ephedra. The earliest unambiguous records of the group date to the Jurassic, and they achieved their highest diversity during the Early Cretaceous. The primary difference between gnetophytes and other gymnosperms is the presence of vessel elements, a system of small tubes (xylem) that transport water within the plant, similar to those found in flowering plants. Because of this, gnetophytes were once thought to be the closest gymnosperm relatives to flowering plants, but more recent molecular studies have brought this hypothesis into question, with many recent phylogenies finding them to be nested within the conifers.
Ceratophyllaceae is a cosmopolitan family of flowering plants including one living genus commonly found in ponds, marshes, and quiet streams in tropical and in temperate regions. It is the only extant family in the order Ceratophyllales. Species are commonly called coontails or hornworts, although hornwort is also used for unrelated plants of the division Anthocerotophyta.
Welwitschiaceae is a family of plants of the order Gnetales with one living species, Welwitschia mirabilis, found in southwestern Africa. Three fossil genera have been recovered from the Crato Formation – late Aptian strata located in the Araripe Basin in northeastern Brazil, with one of these also being known from the early Late Cretaceous (Cenomanian-Turonian) Akrabou Formation of Morocco.
The Cabombaceae are a family of aquatic, herbaceous flowering plants. A common name for its species is water shield. The family is recognised as distinct in the Angiosperm Phylogeny Group IV system (2016). The family consists of two genera of aquatic plants, Brasenia and Cabomba, totalling six species.
Nepenthes longifolia is a tropical pitcher plant endemic to Sumatra, where it grows at elevations of between 300 and 1100 m above sea level. The specific epithet longifolia, formed from the Latin words longus (long) and folius (leaf), refers to the exceptionally large leaves of this species.
Ulmus changii, occasionally known as the Hangzhou elm, is a small deciduous tree found across much of China in forests at elevations of up to 1800 m. Owing to its increasing scarcity, U. changii was added to the Hainan Province Protected Plants List in 2006.
Ulmus microcarpa was named and first described by the Chinese botanist L. K. Fu, who discovered the tree in the Chayu broad-leaved forests of south-eastern Xizang at altitudes of around 2800 m during the 1973 Qinghai - Tibet Expedition. Unlike the majority of Tibet, the Chayu region has a subtropical highland climate featuring warm, wet, summers and mild, dry, winters. Commonly known as the Tibetan Elm, the tree was introduced to the United States in 2006, and the UK in 2013; it remains one of the rarest species of elm in cultivation.
Ulmus szechuanicaFang, known as the Szechuan (Sichuan), or red-fruited, elm, is a small to medium deciduous Chinese tree found along the Yangtze river through the provinces of Sichuan, Jiangxi, Anhui, and Jiangsu.
Archaeamphora longicervia is a fossil plant species, the only member of the hypothetical genus Archaeamphora. Fossil material assigned to this taxon originates from the Yixian Formation of northeastern China, dated to the Early Cretaceous.
The Dakota is a sedimentary geologic unit name of formation and group rank in Midwestern North America. The Dakota units are generally composed of sandstones, mudstones, clays, and shales deposited in the Mid-Cretaceous opening of the Western Interior Seaway. The usage of the name Dakota for this particular Albian-Cenomanian strata is exceptionally widespread; from British Columbia and Alberta to Montana and Wisconsin to Colorado and Kansas to Utah and Arizona. It is famous for producing massive colorful rock formations in the Rocky Mountains and the Great Plains of the United States, and for preserving both dinosaur footprints and early deciduous tree leaves.
Quillajaceae is a family of flowering plants. It contains only two extant species, Quillaja brasiliensis and Quillaja saponaria, and one fossil species, Dakotanthus cordiformis.
Credneria is an extinct genus in the family or Platanaceae of broad-leaf trees similar to extinct Platanus species that appeared during the Cretaceous. The genus was first described by Zenker (1833) and has formerly been placed in the family Salicaceae rather than Platanaceae on occasion. Credneria leaves are preserved in sandstone and less often in siltstone. The leaves are typically obovate with a pinnate-actinodromous venation and distinct suprabasal veins.
Sapindopsis ("Sapindus-like") is an extinct form genus for leaves of the Cretaceous Period, originally considered similar to soapberry. Associated reproductive structures now suggest it was more closely related to planes and sycamores of the family Platanaceae.

Nymphaea paganuccii is a species of waterlily endemic to Brazil.
Nymphaea lasiophylla is a species of waterlily native to East Brazil. It has also been introduced to the Venezuelan Antilles.
Nuphar orbiculata is a species of rhizomatous aquatic plant native to the US-American states Alabama, Florida, and Georgia.
Pluricarpellatia peltata was a species of herbaceous aquatic plant, which occurred in the early Cretaceous period of Brazil.
