Nymphaeaceae
Nymphaeaceae () is a family of flowering plants, commonly called water lilies. They live as rhizomatous aquatic herbs in temperate and tropical climates around the world. The family contains nine genera with about 70 known species. Water lilies are rooted in soil in bodies of water, with leaves and flowers floating on or emergent from the surface. Leaves are round, with a radial notch in '' Nymphaea'' and ''Nuphar'', but fully circular in ''Victoria'' and ''Euryale''. Water lilies are a well-studied clade of plants because their large flowers with multiple unspecialized parts were initially considered to represent the floral pattern of the earliest flowering plants, and later genetic studies confirmed their evolutionary position as basal angiosperms. Analyses of floral morphology and molecular characteristics and comparisons with a sister taxon, the family Cabombaceae, indicate, however, that the flowers of extant water lilies with the most floral parts are more derived ...

Barclaya
''Barclaya'' is a genus of 3 - 4 species of flowering plants of the family Nymphaeaceae. ''Barclaya'' are aquatic plants native to tropical Asia. The genus was named in honour of the American-born English brewer and patron of science Robert Barclay. Synonym Though ''Hydrostemma'' is a name that is older than the name ''Barclaya'', having been published 6 months earlier, the name ''Barclaya'' has been "conserved" as it was deemed being much better known than ''Hydrostemma''. Taxonomy ''Barclaya'' is sometimes given its own family status as Barclayaceae on the basis of an extended perianth tube (combined sepals and petals) arising from the top of the ovary and by stamens that are joined basally, but morphological and genetic studies support the view that ''Barclaya'' should be retained in the family Nymphaeaceae. Description Plants grow from egg-shaped tubers Tubers are a type of enlarged structure used as storage organs for nutrients in some plants. They are used for the ...

Nuphar
''Nuphar'' is a genus of aquatic plants in the family Nymphaeaceae, with a temperate to subarctic Northern Hemisphere distribution. Common names include water-lily (Eurasian species; shared with many other genera in the same family), pond-lily, alligator-bonnet or bonnet lily, and spatterdock (North American species). Taxonomy The genus is closely related to '' Nymphaea''. ''Nuphar'' differs in that its petals are much smaller than its 4–6 bright yellow-coloured sepals, whereas in ''Nymphaea'', the petals are much larger than the sepals. The genera also differ in the maturation of their fruit; while maturing, ''Nuphar'' fruit remain above water level on their scapes, whereas fruit of ''Nymphaea'' sink below water level immediately after their flowers close, and there they mature. In both genera the leaves float and have a radial notch from the circumference to the point of attachment of the petiole. Depending on the species, the leaves of most species range from cordate to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victoria (plant)
''Victoria'' or giant waterlily is a genus of water-lilies, in the plant family Nymphaeaceae, with very large green leaves that lie flat on the water's surface. ''Victoria boliviana'' has a leaf that is up to in width, on a stalk up to in length. The genus name was given in honour of Queen Victoria of the United Kingdom. It pushes other water plants aside as it spreads out until only those of its kind remains. When this happens it has completely cut out the sunlight from getting to any plants below the water. All three species typically have four sepals each measuring long by wide. There are typically 50 to 70 petals and 150 to 200 stamens. Extant species The first published description of the genus was by John Lindley in 1837, based on specimens returned from British Guiana by Robert Schomburgk. Lindley named the genus after the new Queen, Victoria, and the species ''Victoria regia''. An earlier account of the species, ''Euryale amazonica'' Poeppig, in 1832 descr ...

Euryale Ferox
''Euryale ferox,'' commonly known as prickly waterlily, makhana or Gorgon plant, is a species of water lily found in southern and eastern Asia, and the only extant member of the genus ''Euryale''. The edible seeds, called fox nuts or ''makhana'' when dried, are eaten in Asia. Though normally classified in the water lily family, Nymphaeaceae, the species is occasionally regarded as a distinct family, Euryalaceae. Unlike other water lilies, the pollen grains of ''Euryale'' have three nuclei. Etymology The genus is named after a mythical Greek Gorgon, Euryale. Growth ''Euryale'' ''ferox'' is a perennial plant native to eastern Asia and southern Asia, and is found from northeast India to Korea and Japan, as well as parts of eastern Russia. The Indian state of Bihar produces 90% of the world's fox nuts. It grows in water, producing bright purple flowers. The leaves are large and round, often more than a meter (3 feet) across, with a leaf stalk attached in the centre of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cabombaceae
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. The Cabombaceae are all aquatic, living in still or slow-moving waters of temperate and tropical North and South America, Europe, Asia, Africa, and Australia. Although found on all continents but Antarctica, the plants tend to grow in relatively restricted ranges. The family has an extensive fossil record from the Cretaceous with plants that exhibit affinities to either the Cabombaceae or Nymphaeaceae occurring in the Early Cretaceous. One such likely Cretaceous member is the genus '' Pluricarpellatia'', found in rocks 115 million years old in what is now Brazil. The APG system of 1998 included this family in the water lily family Nymphaeaceae, as did the APG II syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nymphaea Nouchali
''Nymphaea nouchali'', often known by its synonym ''Nymphaea stellata'', or by common names blue lotus, star lotus, red water lily, dwarf aquarium lily, blue water lily, blue star water lily or manel flower, is a water lily of genus ''Nymphaea''. It is native to southern and eastern parts of Asia, and is the national flower of Bangladesh and Sri Lanka. In Sanskrit, it is ''utpala''. This species is usually considered to include the blue Egyptian lotus ''N. nouchali'' var. ''caerulea''. In the past, taxonomic confusion has occurred, with the name ''Nymphaea nouchali'' incorrectly applied to ''Nymphaea pubescens''. Distribution and habitat This aquatic plant is native in a broad region from Afghanistan, the Indian subcontinent, to Taiwan, southeast Asia and Australia. It has been long valued as a garden flower in Thailand and Myanmar to decorate ponds and gardens. In its natural state, ''N. nouchali'' is found in static or slow-flowing aquatic habitats of low to moderate depth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basal Angiosperms
The basal angiosperms are the flowering plants which diverged from the lineage leading to most flowering plants. In particular, the most basal angiosperms were called the ANITA grade, which is made up of '' Amborella'' (a single species of shrub from New Caledonia), Nymphaeales (water lilies, together with some other aquatic plants) and Austrobaileyales (woody aromatic plants including star anise). ''ANITA'' stands for ''Amborella'', ''N''ymphaeales, ''I'' lliciales, ''T''rimeniaceae, and '' Austrobaileya''. Some authors have shortened this to ''ANA''-grade for the three orders, ''A''mborellales, ''N''ymphaeales, and ''A''ustrobaileyales, since the order Iliciales was reduced to the family Illiciaceae and placed, along with the family Trimeniaceae, within the Austrobaileyales. The basal angiosperms are only a few hundred species, compared with hundreds of thousands of species of eudicots, monocots, and magnoliids. They diverged from the ancestral angiosperm lineage before ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomi ...

Pollination Syndrome
Pollination syndromes are suites of flower traits that have evolved in response to natural selection imposed by different pollen vectors, which can be abiotic (wind and water) or biotic, such as birds, bees, flies, and so forth through a process called pollinator-mediated selection. These traits include flower shape, size, colour, odour, reward type and amount, nectar composition, timing of flowering, etc. For example, tubular red flowers with copious nectar often attract birds; foul smelling flowers attract carrion flies or beetles, etc. The "classical" pollination syndromes were first studied in the 19th century by the Italian botanist Federico Delpino. Although they are useful in understanding of plant-pollinator interactions, sometimes the pollinator of a plant species cannot be accurately predicted from the pollination syndrome alone, and caution must be exerted in making assumptions. The naturalist Charles Darwin surmised that the flower of the orchid ''Angraecum sesquipeda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
