Ipheion Sessile
The flowering plant genus ''Ipheion'' (starflower, spring starflower) belongs to Allioideae, a subfamily of the family Amaryllidaceae. The World Checklist of Selected Plant Families no longer recognize the genus, regarding it as a synonym of ''Tristagma'', although The Plant List accepts two species. Description They are small bulbous perennials with narrow grass-like leaves and honey-scented star-shaped flowers in spring, usually in shades of white or pale blue. The genus occurs naturally in Argentina, Uruguay, and southern Brazil, although ''Ipheion uniflorum'' has naturalized elsewhere. Taxonomy History The genus was originally described in 1836 by Constantine Samuel Rafinesque, based on ''Ipheion uniflorum'', separating it from '' Milla uniflora'' Graham (now ''Tristagma''). The original description was unifloral inflorescences with white flowers, spathe formed by one bifid bract, staminal filaments independently fused to the perigonial tube and the fruit being a cla ...

Ipheion Uniflorum
''Ipheion uniflorum'' is a species of flowering plant, related to the onions, so is placed in the allium subfamily (Allioideae) of the Amaryllidaceae. It is known by the common name springstar, or spring starflower. Along with all the species of the genus ''Ipheion'', some sources place it in the genus ''Tristagma'', but research published in 2010 suggested that this is not correct. It is native to Argentina and Uruguay, but is widely cultivated as an ornamental and reportedly naturalized in Great Britain, France, Australia, New Zealand and the United States. Description This is a small herbaceous perennial growing from a bulb and producing flat, shiny, green, hairless, grasslike leaves up to long. The foliage has an onionlike scent when crushed. The stem grows up to tall and bears a solitary showy flower in spring (hence the Latin name ''uniflorum'' - "single flower"). Each honey-scented, star-shaped flower has six pointed lobes up to 3 centimeters long in shades of very pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Molecular Phylogenetic
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. History The theoretical ...

John Hutchinson (botanist)
John Hutchinson, OBE, FRS (7 April 1884 Blindburn, Northumberland – 2 September 1972 London) was an English botanist, taxonomist and author.''A Botanist in Southern Africa'' John Hutchinson (London, 1946) Life and career Born in Blindburn, Wark on Tyne, Northumberland, England, he received his horticultural training in Northumberland and Durham and was appointed a student gardener at Kew in 1904. His taxonomic and drawing skills were soon noticed and resulted in his being appointed to the Herbarium in 1905. He moved from assistant in the Indian section to assistant for Tropical Africa, returning to Indian botany from 1915 to 1919, and from then on was in charge of the African section until 1936 when he was appointed Keeper of the Museums of Botany at Kew. He retired in 1948 but continued working on the phylogeny of flowering plants and publishing two parts of ''The Genera of Flowering Plants''.

Liliaceae
The lily family, Liliaceae, consists of about 15 genera and 610 species of flowering plants within the order Liliales. They are monocotyledonous, perennial, herbaceous, often bulbous geophytes. Plants in this family have evolved with a fair amount of morphological diversity despite genetic similarity. Common characteristics include large flowers with parts arranged in threes: with six colored or patterned petaloid tepals (undifferentiated petals and sepals) arranged in two whorls, six stamens and a superior ovary. The leaves are linear in shape, with their veins usually arranged parallel to the edges, single and arranged alternating on the stem, or in a rosette at the base. Most species are grown from bulbs, although some have rhizomes. First described in 1789, the lily family became a paraphyletic "catch-all" ( wastebasket) group of lilioid monocots that did not fit into other families and included a great number of genera now included in other families and in s ...

William Thomas Stearn
William Thomas Stearn (16 April 1911 – 9 May 2001) was a British botanist. Born in Cambridge in 1911, he was largely self-educated, and developed an early interest in books and natural history. His initial work experience was at a Cambridge bookshop, but he also had a position as an assistant in the university botany department. At the age of 29 he married Eldwyth Ruth Alford, who later became his collaborator, and he died in London in 2001. While at the bookshop, he was offered a position as a librarian at the Royal Horticultural Society in London (1933–1952). From there he moved to the Natural History Museum as a scientific officer in the botany department (1952–1976). After his retirement, he continued working there, writing, and serving on a number of professional bodies related to his work, including the Linnean Society, of which he became president. He also taught botany at Cambridge University as a visiting professor (1977–1983). Stearn is known for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beauverd
Gustave Beauverd (1867–1942) was a Swiss botanist, specializing in Pteridophytes, Bryophytes, and Spermatophytes. For a period of time he worked at the " Herbier Bossier", and is remembered for his investigations of the genus '' Melampyrum''. He was a co-author of the series "Icones florae Alpinae plantarum", and the author of many works on diverse botanical subjects. In 1931 he became a member of the ''Société botanique de France''. He is the taxonomic authority of the genera ''Berroa'', ''Parantennaria'', ''Psychrophyton'' and ''Stuckertiella''. The genus ''Beauverdia'' (family Alliaceae) was named after him by Wilhelm Gustav Franz Herter, and plants with the specific epithet of ''beauverdiana'' honor him, examples being ''Acacia beauverdiana ''Acacia beauverdiana'', commonly known as pukkati, is a member of genus ''Acacia'' that is native to Western Australia. It is a perennial tree tall with multiple stems. It has yellow flowers and it blooms from July to October. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanical Register
''The Botanical Register'', subsequently known as ''Edwards's Botanical Register'', was an illustrated horticultural magazine that ran from 1815 to 1847. It was started by the botanical illustrator Sydenham Edwards, who had previously illustrated '' The Botanical Magazine'', but left after a dispute with the editors. Edwards edited five volumes of ''The Botanical Register'' in five years, before his death in 1819. During this period, the text was provided by John Bellenden Ker Gawler, and Edwards himself provided paintings, which were engraved and hand-coloured by others. After Edwards' death, editorial duties passed to the publisher, James Ridgway, who issued a further nine volumes between 1820 and 1828. In 1829, John Lindley was appointed editor, and he adopted the title ''Edwards's Botanical Register''. A further nineteen volumes were issued before the magazine was discontinued in 1847. In 1839, Lindley also issued an ''Appendix to the First Twenty-Three Volumes of Edwards's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Lindley
John Lindley FRS (5 February 1799 – 1 November 1865) was an English botanist, gardener and orchidologist. Early years Born in Catton, near Norwich, England, John Lindley was one of four children of George and Mary Lindley. George Lindley was a nurseryman and pomologist and ran a commercial nursery garden. Although he had great horticultural knowledge, the undertaking was not profitable and George lived in a state of indebtedness. As a boy he would assist in the garden and also collected wild flowers he found growing in the Norfolk countryside. Lindley was educated at Norwich School. He would have liked to go to university or to buy a commission in the army but the family could not afford either. He became Belgian agent for a London seed merchant in 1815. At this time Lindley became acquainted with the botanist William Jackson Hooker who allowed him to use his botanical library and who introduced him to Sir Joseph Banks who offered him employment as an assistant in his ...

Themidaceae
Brodiaeoideae are a monocot subfamily of flowering plants in the family Asparagaceae, order Asparagales. They have been treated as a separate family, Themidaceae. They are native to Central America and western North America, from British Columbia to Guatemala.Ole Seberg. 2007. "Themidaceae" page 404. In: Vernon H. Heywood, Richard K. Brummitt, Ole Seberg, and Alastair Culham. ''Flowering Plant Families of the World''. Firefly Books: Ontario, Canada. The name of the subfamily is based on the type genus '' Brodiaea''. In molecular phylogenetic analyses, Brodiaeoideae is strongly supported as monophyletic. It is probably sister to Scilloideae.J. Chris Pires, Ivan J. Maureira, Thomas J. Givnish, Kenneth J.

Beauverdia
''Beauverdia'' is a genus of South American plants in the onion subfamily within Amaryllis family, native to Brazil, Uruguay, and Argentina. The plants are bulb-forming perennial herbs. Affinities and classification of the species are unresolved at present, and require additional investigation. In 1972, genus '' Ipheion'' was divided into two sections, '' Hirtellum'' and '' Ipheion''. However, the development of phylogenetic analysis revealed that '' Ipheion'' was not monophyletic, although the division into sections was later supported. ''Beauverdia'' Herter had been first described in 1943 as a genus with 10 species. Originally it was created to distinguish those species with single-flowered inflorescences from others with many-flowered inflorescences within ''Nothoscordum'' and other genera, some of them no longer considered members of the Amaryllidaceae. Some authors declined to regard the group as a distinct genus, preferring to consider the name a synonym of '' Ipheion.'' ...
