Lophospermum Scandens
''Lophospermum scandens'' is a scambling or climbing herbaceous perennial native to south central Mexico, with red-violet and white tubular flowers and toothed heart-shaped leaves. It grows at elevations between in dry habitats, including deciduous oak forests and recent lava flows. The long-tubed flowers are pollinated by hummingbirds. It has been used in gardens as an ornamental plant since the mid-19th century. Its roots require protection from frost in regions where this occurs in the winter. Hybrids of ''L. scandens'' are also grown. ''Lophospermum scandens'' has been confused with ''Lophospermum erubescens'', partly because the earliest illustration of ''L. erubescens'' was labelled as ''L. scandens''. Among other differences, ''L. scandens'' has a less climbing habit than ''L. erubescens'', with few twining leaf stalks; also the sepals are narrower and joined at the base for rather than only . In horticulture it often appears under the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nomen Illegitimum
''Nomen illegitimum'' (Latin for illegitimate name) is a technical term, used mainly in botany. It is usually abbreviated as ''nom. illeg.'' Although the International Code of Nomenclature for algae, fungi, and plants uses Latin terms for other kinds of name (e.g. ''nomen conservandum'' for " conserved name"), the glossary defines the English phrase "illegitimate name" rather than the Latin equivalent.''Melbourne Code''Glossary/ref> However, the Latin abbreviation is widely used by botanists and mycologists. A superfluous name is often an illegitimate name. Again, although the glossary defines the English phrase, the Latin equivalent ''nomen superfluum'', abbreviated ''nom. superfl.'' is widely used by botanists. Definition A ''nomen illegitimum'' is a validly published name, but one that contravenes some of the articles laid down by the International Botanical Congress.

Peduncle (botany)
In botany, a peduncle is a stalk supporting an inflorescence or a solitary flower, or, after fecundation, an infructescence or a solitary fruit. The peduncle sometimes has bracts (a type of cataphylls) at nodes. The main axis of an inflorescence above the peduncle is the rachis. There are no flowers on the peduncle but there are flowers on the rachis. When a peduncle arises from the ground level, either from a compressed aerial stem or from a subterranean stem (rhizome, tuber, bulb, corm), with few or no bracts except the part near the rachis or receptacle, it is referred to as a scape. The acorns of the pedunculate oak are borne on a long peduncle, hence the name of the tree. See also *Pedicel (botany) *Scape (botany) In botany, a scape is a peduncle arising from a subterranean or very compressed stem, with the lower internodes very long and hence few or no bracts except the part near the rachis or receptacle. Typically it takes the form of a long, leafles ... Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Phylogeny
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Asa Gray
Asa Gray (November 18, 1810 – January 30, 1888) is considered the most important American botanist of the 19th century. His ''Darwiniana'' was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built an extensive ne ...

New Spain
New Spain, officially the Viceroyalty of New Spain ( es, Virreinato de Nueva España, ), or Kingdom of New Spain, was an integral territorial entity of the Spanish Empire, established by Habsburg Spain during the Spanish colonization of the Americas and having its capital in Mexico City. Its jurisdiction comprised a huge area that included what is now Mexico, the Western and Southwestern United States (from California to Louisiana and parts of Wyoming, but also Florida) in North America; Central America, the Caribbean, very northern parts of South America, and several territorial Pacific Ocean archipelagos. After the 1521 Spanish conquest of the Aztec empire, conqueror Hernán Cortés named the territory New Spain, and established the new capital, Mexico City, on the site of the Tenochtitlan, the capital of the Mexica (Aztec) Empire. Central Mexico became the base of expeditions of exploration and conquest, expanding the territory claimed by the Spanish Empire. With the polit ...

José Mariano Mociño
José Mariano Mociño Suárez Lozano (24 September 1757 – 12 June 1820), or simply José Mariano Mociño, was a naturalist from New Spain. After having studied philosophy and medicine, he conducted early research on the botany, geology, and anthropology of his country and other parts of North America. Biography He was born in Temascaltepec (modern-day Mexico State) in 1757. Being poor, he worked in many different jobs to study in the ''Seminario Tridentino de México'', where he devoted himself especially to physics, mathematics, botany, and chemistry. In 1778 he graduated in philosophy. In 1791 he was called to join the scientific expedition of Martín de Sessé, the Royal Botanical Expedition, which had started in 1787. They traveled across New Spain, reaching the most inhospitable places of the Empire, being especially notable his trips to the Pacific Northwest. Although the pay for his job was minimal, he created one of the most important natural history collections of his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martín Sessé Y Lacasta
Martín Sessé y Lacasta (December 11, 1751 – October 4, 1808) was a Spanish botanist, who relocated to New Spain (now Mexico) during the 18th century to study and classify the flora of the territory. Background Sessé studied medicine in Zaragoza, then moved to Madrid in 1775. In 1779 he became a military physician, in which capacity he visited Cuba, and later New Spain. In 1785 he was named a commissioner of the Royal Botanical Garden in New Spain. At the same time a botanical garden and a course of study on the flora of Mexico at the Royal and Pontifical University of Mexico (now UNAM) were authorized. Sessé stopped practicing medicine in order to devote all his energies to botany. The botanical expedition In 1786 Charles III, King of Spain, authorized a major botanical expedition known as the Royal Botanical Expedition to New Spain, that was proposed by Sessé at a time when most of the flora and fauna of Mexico were unknown to European science. Sessé became the head ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locule
A locule (plural locules) or loculus (plural loculi) (meaning "little place" in Latin) is a small cavity or compartment within an organ or part of an organism (animal, plant, or fungus). In angiosperms (flowering plants), the term ''locule'' usually refers to a chamber within an Ovary (plants), ovary (gynoecium or carpel) of the flower and fruits. Depending on the number of locules in the ovary, fruits can be classified as ''uni-locular'' (unilocular), ''bi-locular'', ''tri-locular'' or ''multi-locular''. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the ovules or seeds. The term may also refer to chambers within anthers containing pollen. In Ascomycete fungi, locules are chambers within the hymenium in which the perithecium, perithecia develop.

Ovary (botany)
In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals. The pistil may be made up of one carpel or of several fused carpels (e.g. dicarpel or tricarpel), and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above the ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each individual pollen grain, to fertilize one individual ovule. Some wind pollinated flowers have much reduced and modified ovaries. Fruits A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm. Because gymnosperms do not have an ovary but reproduce through double fertilization of unprotected ovules, they produce naked seeds that do not ...
