Reader 19 05 19 V75 Timeline Pagination Plant Trivia TimeLine A Chronology of Plants and People The TimeLine presents world history from a botanical viewpoint. It includes brief stories of plant discovery and use that describe the roles of plants and plant science in human civilization. The Time- Line also provides you as an individual the opportunity to reflect on how the history of human interaction with the plant world has shaped and impacted your own life and heritage. Information included comes from secondary sources and compila- tions, which are cited. The author continues to chart events for the TimeLine and appreciates your critique of the many entries as well as suggestions for additions and improvements to the topics cov- ered.

    BOTANY,Semester 02,MBOTCC 06,Contemporary system of classification:Armen Takhtajan,D.K.Jha (lecture series no. 06). ARMEN TAKHTAJAN (B.1910) was Head of the Dept. Of Plant Science at Leningrad,Russia.He presented a system of classification of Angiosperms for the first in 1942 and thereafter it’s revised versions in 1954,1966,1969 and finally in 1980 in his book in English entitled Flowering Plants ;Origin and Dispersal.His system is basically inspired by Bassey_Hallier tradition as he also considered evidences from fields like Morphology,Anatomy, Embryology, Cytology,Palynology ,Chemistry etc. According to Takhtajan angiosperms aremonophyletic in origin and have derived from Gymnosperms.Monocots are derived from some primitive dicots. Takhtajans classification is based on some phyletic principles: 1Woody plants are primitive than herbaceous plants. 2.Deciduous woody plants are derived from evergreen plants. 3.Stomata without subsidiary cells are more advanced than stomata with subsidiary cells. 4 .Alternate lead phyllotaxy is more primitive than other types. 5.Parallel venation is advanced. 6.Cymose inflorescence is primitive than racehorse. 7.Polymerous flowers are primitive. 8 Pollen with smooth exine is primitive than sculptured exine. 9. Apocarpous gynoecium is more primitive than syncarpous. 10.Bitegmic ovules are more primitive than unitegmic. 11.Anatropous ovules are more primitive than others. 12.Polygonum type embryosac is most primitive. 13.Porogamic condition is more primitive than mesogamic and chalazogamic. 14. Many seeded follicle fruits are most primitive. 15. Endospermic seeds are primitive.Dicot embryo is primitive than monocot embryo. Brief outline of Takhtajans system Takhtajan has replaced traditional nomenclature of Angiosperm,Dicotyledonae and Monocotyledonae by Magnoliophyta,Magnoliopsida and Liliopsida respectively.

  • Of Dahlia Myths.Pub
    Cavanilles’ detailed illustrations established the dahlia in the botanical taxonomy In 1796, the third volume of “Icones” introduced two more dahlia species, named D. coccinea and D. rosea. They also were initially thought to be sunflowers and had been brought to Spain as part of the Alejandro Malaspina/Luis Neé expedition. More than 600 drawings brought the plant collection to light. Cavanilles, whose extensive correspondence included many of Europe’s leading botanists, began to develop a following far greater than his title of “sacerdote” (priest, in French Abbé) ever would have offered. The A. J. Cavanilles archives of the present‐day Royal Botanical Garden hold the botanist’s sizable oeu‐ vre, along with moren tha 1,300 letters, many dissertations, studies, and drawings. In time, Cavanilles achieved another goal: in 1801, he was finally appointed professor and director of the garden. Regrettably, he died in Madrid on May 10, 1804. The Cavanillesia, a tree from Central America, was later named for this famousMaterial Spanish scientist. ANDERS DAHL The lives of Dahl and his Spanish ‘godfather’ could not have been any more different. Born March 17,1751, in Varnhem town (Västergötland), this Swedish botanist struggled with health and financial hardship throughout his short life. While attending school in Skara, he and several teenage friends with scientific bent founded the “Swedish Topographic Society of Skara” and sought to catalogue the natural world of their community. With his preacher father’s support, the young Dahl enrolled on April 3, 1770, at Uppsala University in medicine, and he soon became one of Carl Linnaeus’ students.

Petersen Department of Ecology & Evolutionary Biology, University of Tennessee Knoxville, TN 37919-1100 Correspondence to: [email protected] Abstract—The Morrill Act of 1862 afforded the US states the opportunity to found state colleges with agriculture as part of their mission—the so-called “land-grant colleges.” The Hatch Act of 1887 gave the same opportunity for agricultural experiment stations as functions of the land-grant colleges, and the “third Morrill Act” (the Smith-Lever Act) of 1914 added an extension dimension to the experiment stations. Overall, the end of the 19th century and the first quarter of the 20th was a time for growing appreciation for, and growth of institutional education in the natural sciences, especially botany and its specialties, mycology, and phytopathology. This paper outlines a particular genealogy of mycologists and plant pathologists representative of this era. Professor Albert Nelson Prentiss, first of Michigan State then of Cornell, Professor William Russel Dudley of Cornell and Stanford, Professor Mason Blanchard Thomas of Wabash College, and Professor Herbert Hice Whetzel of Cornell Plant Pathology were major players in the scenario. The supporting cast, the students selected, trained, and guided by these men, was legion, a few of whom are briefly traced here. Key words—“New Botany,” European influence, agrarian roots Chapter 1.

Y'." c:::: d.... c.... m... DUTCH ELM DISEASE Graphium ulmi Introduction HE DUTCHELM DISEASE is the common name of a trouble first described T from Holland in 1921, and nine years later identified in the United States. Early in its history this disease was found to be caused by a fungus new to science and called Graphium ulmi, ulmi being the generic name of the host upon which it occurred. Later it was discovered that this Graphium is only a stage in the life history of the fungus and that its mature stage is an Ascomycete of the genus Ceratostomella. Therefore tlie fungus is now usually called Ceraloslomella ulmi. More recently still the genus Ceratostomella has been divided, and the elm fungus has been placed by Nannfeldt (39) under the genus Ophiostoma, becoming Ophi- osloma ulmi. So we have at least three scientific names for the Dutch elm disease. As the imperfect stages of the fungus cause the injury to elm trees, in this laboratory we use the one name Graphium ulmi, rather than its saprophytic asco stage, though another imperfect stage, known usually as Cephalosporium, is associated with the tiraphium but is less distinct in its fruiting structure. The Dutch elm disease was fitfound in this country in Ohio in 1930. After several preliminary searches it was discovered in Connecticut a few years later. Because of the seriousness of the disease and the importance of the elm as a shade tree, the Station began to study the fungus and to co6perate wi1.h tlie United States Department of Agricnltnre in its control.

  • THE STUDY of SATURN's RINGS 1 Thesis Presented for the Degree Of
    1 THE STUDY OF SATURN'S RINGS 1610-1675, Thesis presented for the Degree of Doctor of Philosophy in the Field of History of Science by Albert Van Haden Department of History of Science and Technology Imperial College of Science and Teohnology University of London May, 1970 2 ABSTRACT Shortly after the publication of his Starry Messenger, Galileo observed the planet Saturn for the first time through a telescope. To his surprise he discovered that the planet does.not exhibit a single disc, as all other planets do, but rather a central disc flanked by two smaller ones. In the following years, Galileo found that Sa- turn sometimes also appears without these lateral discs, and at other times with handle-like appendages istead of round discs. These ap- pearances posed a great problem to scientists, and this problem was not solved until 1656, while the solution was not fully accepted until about 1670. This thesis traces the problem of Saturn, from its initial form- ulation, through the period of gathering information, to the final stage in which theories were proposed, ending with the acceptance of one of these theories: the ring-theory of Christiaan Huygens. Although the improvement of the telescope had great bearing on the problem of Saturn, and is dealt with to some extent, many other factors were in- volved in the solution of the problem. It was as much a perceptual problem as a technical problem of telescopes, and the mental processes that led Huygens to its solution were symptomatic of the state of science in the 1650's and would have been out of place and perhaps impossible before Descartes.
