Triantha
''Triantha'' is a small genus of flowering plants in the family Tofieldiaceae, first described as a genus in 1879. False asphodel is a common name for plants in this genus. ''Triantha'' has four known species. One of these is endemic to Japan. The other three are native to North America. A comparison of DNA sequences has indicated that ''Triantha glutinosa'' might be two species.Hiroshi Azuma and Hiroshi Tobe. 2011. "Molecular phylogenetic analyses of Tofieldiaceae (Alismatales): family circumscription and intergeneric relationships". ''Journal of Plant Research'' 124(3):349-357. Before the family Tofieldiaceae was established in 1995, ''Triantha'' and related genera were usually placed in Nartheciaceae, Liliaceae, or Melanthiaceae, but molecular phylogenetic studies of monocots and Alismatales have shown that inclusion of ''Triantha'' etc. in these families makes them polyphyletic. Some authors have included ''Triantha'' within the genus ''Tofieldia''. ''Triantha'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triantha Occidentalis
''Triantha occidentalis'', the western false asphodel, is a species of carnivorous flowering plant in the family Tofieldiaceae. It is found in the Pacific Northwest. Botanical history ''Triantha occidentalis'' was described by Sereno Watson in 1879 as ''Tofieldia occidentalis'', and reassigned to '' Triantha'' by R. R. Gates in 1918. The carnivorous behavior of the plant was discovered in 2021 by a group of scientists from the University of British Columbia and the University of Wisconsin–Madison. Range The native range of ''Triantha occidentalis'' is from Southeast Alaska to Central California. The range includes the US states of Alaska, California, Idaho, Montana, Oregon, Washington, and Wyoming and the Canadian provinces of Alberta and British Columbia. Carnivory ''Triantha occidentalis'' is a carnivorous plant; the flower stems are covered in a sticky substance, and have tiny hairs that produce a digestive enzyme, a phosphatase. The sticky substance is able to trap small ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triantha Glutinosa
''Triantha glutinosa'' is a species of flowering plant in the Tofieldiaceae family. It is commonly known as the sticky false asphodel, sticky tofieldia or northern bog asphodel, is a species of flowering plant in the tofieldia family. It is native primarily to northern North America, where it is found in Canada and the United States. There are also disjunct populations south in the Appalachian Mountains. Its preferred habitat is wet areas such as marshes and seeps, particularly in calcareous soils. It produces white-yellow flowers in the summer. An intermediate population that suggests a transition to the more southern ''Triantha racemosa'' is found in the New Jersey Pine Barrens The New Jersey Pine Barrens, also known as the Pinelands or simply the Pines, is the largest remaining example of the Atlantic coastal pine barrens ecosystem, stretching across more than seven counties of New Jersey.

Tofieldiaceae
Tofieldiaceae is a family of flowering plants in the monocot order Alismatales.Vernon H. Heywood, Richard K. Brummitt, Ole Seberg, and Alastair Culham. ''Flowering Plant Families of the World''. Firefly Books: Ontario, Canada. (2007). . The family is divided into four genera, which together comprise 28 known species (Christenhusz & Byng 2016 ). They are small, herbaceous plants, mostly of arctic and subarctic regions, but a few extend further south, and one genus is endemic to northern South America and Florida. ''Tofieldia pusilla'' is sometimes grown as an ornamental.Anthony Huxley, Mark Griffiths, and Margot Levy (1992). ''The New Royal Horticultural Society Dictionary of Gardening''.

Carnivorous Plant
Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods. Carnivorous plants still generate some of their energy from photosynthesis. Carnivorous plants have adapted to grow in places where the soil is thin or poor in nutrients, especially nitrogen, such as acidic bogs. They can be found on all continents except Antarctica, as well as many Pacific islands. In 1875 Charles Darwin published ''Insectivorous Plants'', the first treatise to recognize the significance of carnivory in plants, describing years of painstaking research. True carnivory is believed to have evolved independently at least 12 times in five different orders of flowering plants, and is represented by more than a dozen genera. This classification includes at least 583 species that attract, trap, and kill prey, absorbing the resulting available nutrients. Venus flytrap (''Dionaea muscipula''), pitcher p ...

Tofieldia
''Tofieldia'' is a small genus of flowering plants described as a genus in 1778. It is widespread across much of Europe, Asia, and North America. includes photos and European distribution maps ''Tofieldia'' was once placed in the Liliaceae, lily family, but now generally included in the newer family Tofieldiaceae. The genus sometimes includes species of genus ''Triantha''. ''Tofieldia'' are rhizome, rhizomatous perennial herbs with spikes or racemes of lily-like flowers.

Alismatales
The Alismatales (alismatids) are an order of flowering plants including about 4,500 species. Plants assigned to this order are mostly tropical or aquatic. Some grow in fresh water, some in marine habitats. Description The Alismatales comprise herbaceous flowering plants of often aquatic and marshy habitats, and the only monocots known to have green embryos other than the Amaryllidaceae. They also include the only marine angiosperms growing completely submerged, the seagrasses. The flowers are usually arranged in inflorescences, and the mature seeds lack endosperm. Both marine and freshwater forms include those with staminate flowers that detach from the parent plant and float to the surface. There they can pollinate carpellate flowers floating on the surface via long pedicels. In others, pollination occurs underwater, where pollen may form elongated strands, increasing chance of success. Most aquatic species have a totally submerged juvenile phase, and flowers are eithe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honshu
, historically called , is the largest and most populous island of Japan. It is located south of Hokkaidō across the Tsugaru Strait, north of Shikoku across the Inland Sea, and northeast of Kyūshū across the Kanmon Straits. The island separates the Sea of Japan, which lies to its north and west, from the North Pacific Ocean to the south and east. It is the seventh-largest island in the world, and the second-most populous after the Indonesian island of Java. Honshu had a population of 104 million , constituting 81.3% of the entire population of Japan, and is mostly concentrated in the coastal areas and plains. Approximately 30% of the total population resides in the Greater Tokyo Area on the Kantō Plain. As the historical center of Japanese cultural and political power, the island includes several past Japanese capitals, including Kyōto, Nara and Kamakura. Much of the island's southern shore forms part of the Taiheiyō Belt, a megalopolis that spans several o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between org ...

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 t ...

Phylogenetic Tree
A phylogenetic tree (also phylogeny or evolutionary tree Felsenstein J. (2004). ''Inferring Phylogenies'' Sinauer Associates: Sunderland, MA.) is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. All life on Earth is part of a single phylogenetic tree, indicating common ancestry. In a ''rooted'' phylogenetic tree, each node with descendants represents the inferred most recent common ancestor of those descendants, and the edge lengths in some trees may be interpreted as time estimates. Each node is called a taxonomic unit. Internal nodes are generally called hypothetical taxonomic units, as they cannot be directly observed. Trees are useful in fields of biology such as bioinformatics, systematics, and phylogenetics. ''Unrooted'' trees illustrate only the relatedness of the leaf nodes and do not require the ancestral root ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have t ...
