Normanbokea
''Turbinicarpus'' is a genus of very small to medium-sized cacti, which inhabit the north-eastern regions of Mexico, in particular the states of San Luis Potosí, Guanajuato, Nuevo León, Querétaro, Hidalgo, Coahuila, Tamaulipas and Zacatecas. Taxonomy The taxon was first proposed by Curt Backeberg Curt Backeberg (2 August 1894 in Lüneburg, Germany – 14 January 1966) was a German horticulturist especially known for the collection and classification of cacti. Biography He travelled extensively through Central and South America, and publis ... as ''Strombocactus'' subgenus ''Turbinicarpus''. It was elevated to a genus in 1937 by Franz Buxbaum and Backeberg. The Circumscription (taxonomy), circumscription of ''Turbinicarpus'' has been described as "remarkably unstable", with species regularly transferred to other genera.

Guggenheim Memorial Fellowship
Guggenheim Fellowships are grants that have been awarded annually since by the John Simon Guggenheim Memorial Foundation to those "who have demonstrated exceptional capacity for productive scholarship or exceptional creative ability in the arts." Each year, the foundation issues awards in each of two separate competitions: * One open to citizens and permanent residents of the United States and Canada. * The other to citizens and permanent residents of Latin America and the Caribbean. The Latin America and Caribbean competition is currently suspended "while we examine the workings and efficacy of the program. The U.S. and Canadian competition is unaffected by this suspension." The performing arts are excluded, although composers, film directors, and choreographers are eligible. The fellowships are not open to students, only to "advanced professionals in mid-career" such as published authors. The fellows may spend the money as they see fit, as the purpose is to give fellows "b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpha Tau Omega
Alpha Tau Omega (), commonly known as ATO, is an American social fraternity founded at the Virginia Military Institute in 1865 by Otis Allan Glazebrook. The fraternity has around 250 active and inactive chapters and colonies in the United States and has initiated more than 229,000 members. VMI Cadets are no longer associated with the fraternity. In 1885, the VMI Board of Visitors ruled that cadets could no longer join fraternities based on the belief that allegiance to a fraternal group undermined the cohesiveness of and loyalty to the Corps of Cadets. Alpha Tau Omega represents one-third of the Lexington Triad, along with Kappa Alpha Order and Sigma Nu. The Fraternity does not have chapters or affiliations outside the United States. The fraternity's non-profit organization is The ATO Foundation, which provides scholarships to its members. History Alpha Tau Omega was founded at the Virginia Military Institute on September 11, 1865, by Otis Allan Glazebrook, Erskine Mayo Ro ...

Phi Beta Kappa
The Phi Beta Kappa Society () is the oldest academic honor society in the United States, and the most prestigious, due in part to its long history and academic selectivity. Phi Beta Kappa aims to promote and advocate excellence in the liberal arts and sciences, and to induct the most outstanding students of arts and sciences at only select American colleges and universities. It was founded at the College of William and Mary on December 5, 1776, as the first collegiate Greek-letter fraternity and was among the earliest collegiate fraternal societies. Since its inception, 17 U.S. Presidents, 40 U.S. Supreme Court Justices, and 136 Nobel Laureates have been inducted members. Phi Beta Kappa () stands for ('), which means "Wisdom it. love of knowledgeis the guide it. helmsmanof life". Membership Phi Beta Kappa has chapters in only about 10% of American higher learning institutions, and only about 10% of these schools' Arts and Sciences graduates are invited to join the soc ...

American Journal Of Botany
The ''American Journal of Botany'' is a monthly peer-reviewed scientific journal which covers all aspects of plant biology. It has been published by the Botanical Society of America since 1914. The journal has an impact factor of 3.038, as of 2019. As of 2018, access is available through the publisher John Wiley & Sons ( Wiley). From 1951 to 1953, Oswald Tippo served as its editor; the current editor is Pamela Diggle. History In the early 20th century, the field of botany was rapidly expanding, but the publications in which botanists could publish remained limited and heavily backlogged. By 1905, it was estimated that 250,000 contributions were generated in 8 or 9 languages. At the 1911 annual meeting of the society in Washington D.C., it was noted that at least 300 pages of American botanical contributions were sent abroad for publication, with a backlog resulting in a one-year delay in publication. On 31 December 1907, the Botanical Society of America met in Chicago and formal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gynoecium
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are cal ...

Plant Anatomy
Plant anatomy or phytotomy is the general term for the study of the internal structure of plants. Originally it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century plant anatomy has been considered a separate field referring only to internal plant structure. Plant anatomy is now frequently investigated at the cellular level, and often involves the sectioning of tissues and microscopy. Structural divisions Some studies of plant anatomy use a systems approach, organized on the basis of the plant's activities, such as nutrient transport, flowering, pollination, embryogenesis or seed development. Others are more classically divided into the following structural categories: : Flower anatomy, including study of the Calyx, Corolla, Androecium, and Gynoecium : Leaf anatomy, including study of the Epidermis, stomata and Palisade cells : Stem anatomy, including Stem structure and vascular tissues, ...

Johns Hopkins University
Johns Hopkins University (Johns Hopkins, Hopkins, or JHU) is a private research university in Baltimore, Maryland. Founded in 1876, Johns Hopkins is the oldest research university in the United States and in the western hemisphere. It consistently ranks among the most prestigious universities in the United States and the world. The university was named for its first benefactor, the American entrepreneur and Quaker philanthropist Johns Hopkins. Hopkins' $7 million bequest to establish the university was the largest philanthropic gift in U.S. history up to that time. Daniel Coit Gilman, who was inaugurated as Johns Hopkins's first president on February 22, 1876, led the university to revolutionize higher education in the U.S. by integrating teaching and research. In 1900, Johns Hopkins became a founding member of the American Association of Universities. The university has led all U.S. universities in annual research expenditures over the past three decades.
