David Griffiths (botanist)
David Griffiths (1867–1935) was an early 20th century American agronomist and botanist who was a specialist on fungi and on spermatophytes, seed-producing plants, especially cacti. Biography David Griffiths grew up in Dakota Territory after his family emigrated there from his birthplace of Aberystwyth, Wales. He attended South Dakota Agricultural College, receiving both a B.A. (1892) and an MSc (1893) from that institution. For a few years after leaving college, he taught high school science classes. In 1898, he began doctoral studies at Columbia University, focusing on fungi and publishing on such agriculturally important fungal diseases as powdery mildew, ergots, and Smut (fungus), smuts. After gaining his Ph.D. degree in 1900, he became a professor of botany at the University of Arizona Experiment Station, where he studied desert plants. A year later, he moved to the Bureau of Plant Industry of the United States Department of Agriculture, where he would spend a decade and a ha ...

Fungi
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exsiccata
Exsiccata (Latin, ''gen.'' -ae, ''plur.'' -ae) is a work with "published, uniform, numbered set[s] of preserved specimens distributed with printed labels". Typically, exsiccatae are numbered collections of dried herbarium Biological specimen, specimens or preserved biological sample (material), samples published in several duplicate sets with a common theme or title, such as ''Lichenes Helvetici exsiccati'' (see figure). Exsiccatae are regarded as scientific contributions of the editor(s) with characteristics from the library world (published booklets of scientific literature, with authors/ editing, editors, titles, often published in Serial (publishing), serial publications like journals and magazines and in Serial_(literature), serial formats with fascicles) and features from the herbarium world (uniform and numbered collections of duplicate herbarium specimens). Exsiccatae works represent a special method of scholarly communication. The text in the printed matters/published book ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

19th-century American Botanists
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It was characterized by vast social upheaval. Slavery was Abolitionism, abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems an ...

People From Aberystwyth
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1867 Births
There were only 354 days this year in the newly purchased territory of Alaska. When the territory transferred from the Russian Empire to the United States, the calendric transition from the Julian to the Gregorian Calendar was made with only 11 days instead of 12 during the 19th century.

Celastraceae
The Celastraceae (staff-vine or bittersweet) are a family of 98 genera and 1,350 species of herbs, vines, shrubs and small trees, belonging to the order Celastrales. The great majority of the genera are tropical, with only ''Celastrus'' (the staff vines), ''Euonymus'' (the spindle (shrub), spindles) and ''Maytenus'' widespread in temperate climates, and ''Parnassia'' (bog-stars) found in alpine and arctic climates. Of the 98 currently recognized genera of the family Celastraceae, 19 are native to Madagascar and these include at least 57 currently recognized species. Six of these 19 genera (''Brexiella'', ''Evonymopsis'', ''Hartogiopsis'', ''Polycardia'', ''Ptelidium'', and ''Salvadoropsis'') are endemic to Madagascar. These genera each have distinctive traits and functions of their own.
