Stenomesson Korsakoffii
''Stenomesson korsakoffii'' is a species of plant in the family Amaryllidaceae native to Peru. It was formerly known as ''Caliphruria korsakoffii'' and ''Urceolina korsakoffii.'' A 2020 molecular phylogenetic study indicated that this species is sister A sister is a woman or a girl who shares parents or a parent with another individual; a female sibling. The male counterpart is a brother. Although the term typically refers to a familial relationship, it is sometimes used endearingly to ref ... to the other species of '' Stenomesson''.

Hamilton Paul Traub
Hamilton Paul Traub (June 18, 1890 – July 14, 1983) was an American botanist. He specialized in the study of Amaryllidaceae. He also did horticultural studies on beans. Dr Traub was one of the founding members of the American Amaryllis Society (now the International Bulb Society) in 1933, and for a long time the editor of its annual publication, variously called ''Year Book, American Amaryllis Society'', ''Herbertia'' and ''Plant Life: Amaryllis Year Book''.

Alan Meerow
Alan W. Meerow is an American botanist, born in New York City in 1952. He specializes in the taxonomy of the family Amaryllidaceae and the horticulture of palms and tropical ornamental plants. He also works on the population genetics and molecular systematics of cycads and palms. He studied at the Bronx High School of Science and then at the University of New York. Dropping out after a year, aged 19, he moved to Santa Cruz, California. After living on a farm for four years he decided to resume his studies in botany and horticulture at the University of California. Initially his interest in botany was focused on trees, working for three years in the arboretum of the University. He graduated in December 1978 and continued his postgraduate study at the University of Florida, after working for two years at the Marie Selby Botanical Gardens in Sarasota, Florida, where his interest in Amaryllidaceae was stimulated. His master's thesis, in 1983, was on the taxonomy of the genus '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amaryllidaceae
The Amaryllidaceae are a family of herbaceous, mainly perennial and bulbous (rarely rhizomatous) flowering plants in the monocot order Asparagales. The family takes its name from the genus '' Amaryllis'' and is commonly known as the amaryllis family. The leaves are usually linear, and the flowers are usually bisexual and symmetrical, arranged in umbels on the stem. The petals and sepals are undifferentiated as tepals, which may be fused at the base into a floral tube. Some also display a corona. Allyl sulfide compounds produce the characteristic odour of the onion subfamily (Allioideae). The family, which was originally created in 1805, now contains about 1600 species, divided into 71 genera, 17 tribes and three subfamilies, the Agapanthoideae ('' Agapanthus''), Allioideae ( onions, garlic and chives) and Amaryllidoideae ( amaryllis, daffodils, snowdrops). Over time, it has seen much reorganisation and at various times was combined with the related Liliaceae. Sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Phylogenetics
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 phylogenetics, 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 (biology), 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 tre ...

Sister Group
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 taxono ...

Stenomesson
''Stenomesson'' is a genus of bulbous plants in the family Amaryllidaceae. All the species are native to western South America (Colombia, Ecuador, Peru and northern Chile).Meerow, Alan W. 2000. Phylogeny of the American Amaryllidaceae based on nrDNA ITS sequences Systematic Botany 25(4):708-726 Taxonomy It was published by William Herbert in 1821. The lectotype species ''Stenomesson flavum'' was designated by Hamilton Paul Traub in 1963. Etymology The generic name ''Stenomesson'' references the floral morphology. It is composed of the Greek words ''stenos'', meaning narrow, and ''meso'', meaning "in the middle".Weber, O., & Wilkin, P. (2007). 588. ''STENOMESSON PEARCEI'': Amaryllidaceae.

Flora Of Peru
Peru has some of the greatest biodiversity in the world. It belongs to the select group of mega diverse countries because of the presence of the Andes, Amazon rainforest, and the Pacific Ocean. It has the fourth-most tropical forests of any country and the ninth-most forest area. The country is ranked among the five countries with the greatest biodiversity in the world according to various studies. Natural protected areas The 1993 Constitution of Peru recognized the natural resources and ecosystems of Peru as part of its heritage. In 1999, the National System of Natural Areas Protected by the State () was established by the Peruvian government. SINANPE consists of natural areas under national administration, managed and overseen by the National Service of Natural Protected Areas by the State (SERNANP). They also created a map of protection and preservation of historical–cultural heritage and nature. Peru has 76 natural protected areas (more of 15% of the country surface ar ...
