Capsiceae
Capsiceae is a taxonomic tribe of bell peppers and related plants belonging to the Solanoideae subfamily within the family Solanaceae. The tribe was described by Barthélemy Charles Joseph Dumortier in 1827. Phylogenomes Research from spacer data proved that the genera '' Lycianthes'' and ''Capsicum'' together form a highly supported clade that placed them in the tribe. Phylogenetic networks support placing the genera ''Capsicum'' and ''Lycanthes'' within a common bifurcating species tree. The earliest fossils assigned to this tribe are from the Early Eocene of the Green River Formation in Colorado, and can be identified by their trademark calyces. This suggests that the Solanaceae may have originated in North America rather than South America as previously assumed, and were dispersed south during the Paleocene The Paleocene ( ), or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solanoideae
Solanoideae is a subfamily of the flowering plant family Solanaceae, and is sister to the subfamily Nicotianoideae. Within Solanaceae, Solanoideae contains some of the most economically important genera and species, such as the tomato (''Solanum lycopersicum''), potato (''Solanum tuberosum''), eggplant or aubergine (''Solanum melongena''), chili and bell peppers (''Capsicum'' spp.), mandrakes ('' Mandragora'' spp.), and jimson weed ('' Datura stramonium''). This subfamily consists of several well-established tribes: Capsiceae, Datureae, Hyoscyameae, Juanulloeae, Lycieae, Nicandreae, Nolaneae, Physaleae, Solandreae, and Solaneae. The subfamily also contains the contended tribes Mandragoreae and Jaboroseae. Tribal relationships The relationship between the tribes has recently been well described. Nicandreae is the most basal tribe of the family, placing sister to the other 9 (or by some counts 11) tribes. Datureae lies sister to Nicandreae, Physaleae, Capsiceae, ...

Capsicum
''Capsicum'' () is a genus of flowering plants in the Solanum, nightshade family Solanaceae, native to the Americas, cultivated worldwide for their edible fruit, which are generally known as "peppers" or "capsicum". Chili peppers grow on five species of ''Capsicum''. Bell peppers, Sweet or bell peppers and some chili peppers are ''Capsicum annuum'', making it the most cultivated species in the genus. History ''Capsicum'' is native to South America and Central America. These plants have been evolving for 17 million years. It was domesticated and Mesoamerican agriculture, cultivated at least since 3000 BC, as evidenced by remains of chili peppers found in pottery from Puebla and Oaxaca. Etymology and names The generic name may come from Latin , meaning 'box', presumably alluding to the pods; or possibly from the Greek language, Greek word , , 'to gulp'. The name ''pepper'' comes from the similarity of piquance (spiciness or "heat") of the flavor to that of black pepper, ''Piper ( ...

Solanaceae
Solanaceae (), commonly known as the nightshades, is a family of flowering plants in the order Solanales. It contains approximately 2,700 species, several of which are used as agricultural crops, medicinal plants, and ornamental plants. Many members of the family have high alkaloid contents, making some highly toxic, but many—such as tomatoes, potatoes, eggplants, and peppers—are commonly used in food. Originating in South America, Solanaceae now inhabits every continent on Earth except Antarctica. After the K—Pg extinction event they rapidly diversified and have adapted to live in deserts, tundras, rainforests, plains, and highlands, and taken on wide range of forms including trees, vines, shrubs, and epiphytes. Nearly 80% of all nightshades are included in the subfamily Solanoideae, most of which are members of the type genus ''Solanum''. Most taxonomists recognize six other subfamilies: Cestroideae, Goetzeoideae, Nicotianoideae, Petunioideae, Schizanthoideae, an ...

Early Eocene
In the geologic timescale the Ypresian is the oldest age (geology), age or lowest stage (stratigraphy), stratigraphic stage of the Eocene. It spans the time between , is preceded by the Thanetian Age (part of the Paleocene) and is followed by the Eocene Lutetian Age. The Ypresian is consistent with the Lower Eocene (Early Eocene). Events The Ypresian Age begins during the throes of the Paleocene–Eocene Thermal Maximum (PETM). The Fur Formation in Denmark, the Messel shales in Germany, the Oise amber of France and Cambay amber of India are of this age. The Eocene Okanagan Highlands are an uplands subtropical to temperate series of lakes from the Ypresian. The Ypresian is additionally marked by another warming event called the Early Eocene Climatic Optimum (EECO). The EECO is the longest sustained warming event in the Cenozoic record, lasting about 2–3 million years between 53 and 50 Ma. The interval is characterized by low oxygen-18 isotopes, high levels of atmospheric pCO2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycianthes
''Lycianthes'' is a genus of plants from the nightshade family (Solanaceae), found in both the Old World and the New World, but predominantly in the latter. It contains over 150 species, mostly from tropical America, with 35-40 species in Asia and the Pacific. Taxonomy The genus ''Lycianthes'' is closely related to the genus ''Capsicum'', the chili and bell peppers. However, it was long confused with the nightshade Solanaceae (), commonly known as the nightshades, is a family of flowering plants in the order Solanales. It contains approximately 2,700 species, several of which are used as agricultural crops, medicinal plants, and ornamental plants. Many me ...s (genus ''Solanum''), and several little-known ''Solanum'' species have now been reclassified to the genus ''Lycianthes''. Species The following species are recognised in the genus ''Lycianthes'': *'' Lycianthes acapulcensis'' *'' Lycianthes aceratia'' *'' Lycianthes acidochondra'' *'' Lycianthes actinocalyx'' *'' ...

Barthélemy Charles Joseph Dumortier
Barthélemy Charles Joseph Dumortier (; 3 April 1797 – 9 July 1878) was a Belgians, Belgian who conducted a parallel career of botanist and Member of Parliament and is the first discoverer of biological cell division. Over the course of his life, Dumortier named over 688 different taxa, many of which are still in use today. A statue depicting him can be found in Tournai, Belgium, the city where he spent much of his life. The statue was constructed in 1883, by sculptor Charles Fraikin. The statue was damaged by the germans during World War I, but was repaired. Dumortier is depicted in bourgeois clothes, with his right arm folded over his chest and his left arm leaning on political documents supported by a lion. Biography Barthélemy Dumortier was a son of the merchant and city councillor Barthélemy-François Dumortier and of Mariue-Jeanne Willaumez. He married Philippine Ruteau and they had a son, Barthélemy-Noël Dumortier (1830-1915) and seven other children. Barthélemy-Ch ...

Phylogenetic Network
A phylogenetic network is any graph used to visualize evolutionary relationships (either abstractly or explicitly) between nucleotide sequences, genes, chromosomes, genomes, or species. They are employed when reticulation events such as hybridization, horizontal gene transfer, recombination, or gene duplication and loss are believed to be involved. They differ from phylogenetic trees by the explicit modeling of richly linked networks, by means of the addition of hybrid nodes (nodes with two parents) instead of only tree nodes (a hierarchy of nodes, each with only one parent). Phylogenetic trees are a subset of phylogenetic networks. Phylogenetic networks can be inferred and visualised with software such as SplitsTree, the R-package, phangorn, and, more recently, Dendroscope. A standard format for representing phylogenetic networks is a variant of Newick format which is extended to support networks as well as trees. Many kinds and subclasses of phylogenetic networks have bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Green River Formation
The Green River Formation is an Eocene geologic formation that records the sedimentation in a group of intermountain lakes in three basins along the present-day Green River (Colorado River), Green River in Colorado, Wyoming, and Utah. The sediments are deposited in very fine layers, a dark layer during the growing season and a light-hue inorganic layer in the dry season. Each pair of layers is called a varve and represents one year. The sediments of the Green River Formation present a continuous record of six million years. The mean thickness of a varve here is 0.18 mm, with a minimum thickness of 0.014 mm and maximum of 9.8 mm.Bradley, W. H. The varves and climate of the Green River epoch: U.S. Geol. Survey Prof. Paper 158, pp 87–110, 1929. The sedimentary layers were formed in a large area named for the Green River, a tributary of the Colorado River. The three separate basins lie around the Uinta Mountains (north, east, and south) of northeastern Utah: * an area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 Etymology The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively, the sepals are called the ''calyx'' (plural: calyces), the outermost Whorl (botany), whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. The Latin ''calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet'; both words have been used interchangeably in botanical Latin.
