Paleobotany , also spelled as palaeobotany , is the branch of botany dealing with the recovery and identification of plant remains from geological contexts, and their use for the biological reconstruction of past environments ( paleogeography ), and the evolutionary history of plants , with a bearing upon the evolution of life in general. A synonym is paleophytology . It is a component of paleontology and paleobiology . The prefix palaeo- or paleo- means "ancient, old", and is derived from the Greek adjective παλαιός , palaios . Paleobotany includes the study of terrestrial plant fossils , as well as the study of prehistoric marine photoautotrophs , such as photosynthetic algae , seaweeds or kelp . A closely related field is palynology , which is the study of fossilized and extant spores and pollen .
100-555: Marie Charlotte Carmichael Stopes (15 October 1880 – 2 October 1958) was a British author, palaeobotanist and campaigner for eugenics and women's rights . She made significant contributions to plant paleontology and coal classification, and was the first female academic on the faculty of the University of Manchester . With her second husband, Humphrey Verdon Roe , Stopes founded the first birth control clinic in Britain. Stopes edited
200-475: A Birth Control Clinic, where working women are instructed in a method of contraception described by Professor McIlroy as 'The most harmful method of which I have had experience'. When we remember that millions are being spent by the Ministry of Health and by Local Authorities – on pure milk for necessitous expectant and nursing mothers, on Maternity Clinics to guard the health of mothers before and after childbirth, for
300-468: A clinic in Abertillery in 1925. The clinics continued to operate after Stopes' death, but by the early 1970s they were in financial difficulties and in 1975 they went into voluntary receivership . Marie Stopes International was established a year later as an international non-governmental organisation (NGO) working on sexual and reproductive health . The global partnership took over responsibility for
400-402: A declaration not to "impart any information or lend any assistance whatsoever to any person calculated to lead to the destruction in utero of the products of conception". When Stopes learned that one of Avro Manhattan 's friends had had an abortion, she accused him of murdering the unborn child. Her public actions were at odds with her private pronouncements. In a 1919 letter, she had outlined
500-402: A few students, or 'flirt'. During Stopes' time at Manchester, she studied coal and coal balls and researched the collection of Glossopteris (Permian seed ferns). This was an attempt to prove the theory of Eduard Suess concerning the existence of Gondwana or Pangaea . A chance meeting with Antarctic explorer Robert Falcon Scott during one of his fund-raising lectures in 1904 brought
600-546: A follow-up; the already written Wise Parenthood: a Book for Married People , a manual on birth control that was published later that year. Many readers wrote to Stopes for personal advice, which she energetically endeavoured to give. Wise Parenthood was aimed at married women, as Stopes believed birth control to be necessary for married couples to help protect mothers against the exhaustion of excessive childbearing. Although many considered Stopes' advocacy of birth control to be scandalous, Wise Parenthood printed ten editions and
700-462: A message addressed to the bishops which began: "My Lords, I speak to you in the name of God. You are his priests. I am his prophet. I speak to you of the mysteries of man and woman." In 1922, Stopes wrote A New Gospel to All Peoples . The bishops were not receptive; among the resolutions carried during the conference was one aimed against "the deliberate cultivation of sexual union" and another against "indecent literature, suggestive plays and films [and]
800-409: A method of abortion to an unidentified correspondent, and she "was even prepared in some cases to advocate abortion, or, as she preferred to put it, the evacuation of the uterus". In Wise Parenthood , she had promoted the "Gold Pin" or "Spring", which was a "method [that] could be described as an abortifacient". With significant post-war activity Palaeobotanist Paleobotany is important in

If you have missed life's shining goal And mixed with sex perverts and Dopes, For normal soap to cleanse your soul Apply to Marie Stopes. And if perhaps you fail all round And lie among your shattered hopes, Just raise your body from the ground, And crawl to Marie Stopes. Stopes
1000-467: A novel, Love's Creation (1928), under the semi-pseudonym "Marie Carmichael". Publicly, Stopes professed to oppose abortion; during her lifetime, her clinics did not offer that service. She single-mindedly pursued abortion providers and used the police and the courts to prosecute them. Stopes thought that the use of contraceptives was the preferred means by which families should voluntarily limit their number of offspring. Nurses at Stopes' clinic had to sign
1100-567: A particular state of preservation to be placed in organ-genera. In addition, a small subset of organ-genera, to be known as form-genera, were recognised based on the artificial taxa introduced by Brongniart mainly for foliage fossils. The concepts and regulations surrounding organ- and form-genera were modified within successive codes of nomenclature, reflecting a failure of the paleobotanical community to agree on how this aspect of plant taxonomic nomenclature should work (a history reviewed by Cleal and Thomas in 2020 ). The use of organ- and fossil-genera

Prehistoric plants are various groups of plants that lived before recorded history (before about 3500 BC ). Plant fossils can be preserved in a variety of ways, each of which can give different types of information about
1300-855: A possibility of proving Suess's theory. Stopes's passion to prove Suess's theory led her to discuss the possibility of joining Scott's next expedition to Antarctica. She did not join the expedition, but Scott promised to bring back samples of fossils to provide evidence for the theory. Scott died during the 1912 Terra Nova Expedition , but fossils of plants from the Queen Maud Mountains found near Scott's and his companions' bodies provided this evidence. Her study of Carboniferous coal balls with Francis Oliver during her time at University College London proved pivotal, and coupled with Dawkins' and Weiss' influence at Victoria University of Manchester , helped spark Stopes' intrigue in this area of research, aided, in part, by her close proximity to coal seams in
1400-512: A previous endeavour from the year before would come to bear fruit. During her Brora research, Stopes had been in correspondence with several high-profile geologists of the time, including John Wesley Judd and Albert Charles Seward , and these two men helped Stopes secure her first major grant, which she had applied for in 1906. The purpose of this £85 grant was to allow her to conduct her research into Mesozoic coal balls in Japan, and on 19 May 1907, it
1500-661: A revival of Our Ostriches in 1930, Stopes produced two other plays for the London stage, "Don't Tell Timothy", a musical farce produced in 1925–26, and "Buckie's Bears", a children's Christmas pageant, allegedly dictated by her son, Henry Roe-Stopes, produced annually between 1931 and 1936. In collaboration with Joji Sakurai, Stopes produced a translation of three Japanese plays Plays of Old Japan: The Nō in 1913. Stopes published several volumes of poetry, including Man and Other Poems (1913), Love Songs for Young Lovers (1939), Oriri (1940), and Joy and Verity (1952). She also published
1600-978: A rivalry between Stopes and Haire erupted in The Lancet . Haire brought up the gold-pin episode, even though Stopes' clinic had never used it. The issue of the gold pin device resurfaced in the Stopes-Sutherland libel case a few years later. In 1925, the Mothers' Clinic moved to Central London, where it remains as of 2015. Stopes gradually built up a small network of clinics across Britain, working to fund them. She opened clinics in Leeds in April 1934; Aberdeen in October 1934; Belfast in October 1936; Cardiff in October 1937; and Swansea in January 1943. She also helped Beatrice Green establish

This work not only progressed paleobotany but also

Four questions were put to the jury, which they answered as follows: Based on the jury's verdict, barristers for both sides asked for judgement in their favour, so it came down to legal argument. Sutherland's barrister successfully argued that as soon as the jury decided that the statements were true in substance and in fact, that

Her sex manual Married Love (1918) was controversial and influential, and brought the subject of birth control into wide public discourse. Stopes publicly opposed abortion, arguing that the prevention of conception was all that was needed, though her actions in private were at odds with her public pronouncements. In reaction to her controversial beliefs, Marie Stopes International in 2020 changed its name to "MSI Reproductive Choices" with no other changes. Stopes

The Royal Botanic Gardens, Kew states that its mission is to apply scientific discovery and research to fully develop the information about and potential uses of plants and fungi. A conference held in 1976 by the Royal Botanic Gardens Kew was important as it established a co-ordinating body in order to determine which threatened plants are in cultivation and where they are located which played
7400-466: The seeds of fern fronds . It was discovered that some of the "ferns" bore seeds. "Seed ferns" became known and recognized as the missing link between ferns and conifers . They later became known as the pteridosperm . She was provided the opportunity to work with the world's leading experts in paleobotany at the time. Within the same year she won the Gilchrist scholarship from University College London, with
7500-475: The slums of East London. Mayne approached twenty families a day, but after several months she concluded the working class was mistrustful of well-intentioned meddlers. This lack of success made Stopes contemplate a different approach to taking her message to the poor. A conference of Anglican bishops was due to be held in June; not long before the conference, Stopes had a vision. She called in her secretary and dictated
7600-435: The taxon) is defined by the taxonomist who uses the name. Such a change in circumscription could result in an expansion of the range of plant parts or preservation states that could be incorporated within the taxon. For instance, a fossil-genus originally based on compressions of ovules could be used to include the multi-ovulate cupules within which the ovules were originally borne. A complication can arise if, in this case, there
7700-489: The terms "birth control" and " eugenics " were closely related; according to Jane Carey they were "so intertwined as to be synonymous". Following attacks on "the essential fallacies of Malthusian teaching", Sutherland's book attacked Stopes. Under the headings "Specially Hurtful to the Poor" and "Exposing the Poor to Experiment", it read: In the midst of a London slum a woman, who is a doctor of German philosophy (Munich), has opened
7800-466: The type of Mesozoic coal balls she was in search of. This form of geological prediction, 'geoprophesy' as Stopes called it, is formally known as biostratigraphy , and was originally formulated by 17th century Danish scientist Nicholas Steno . Upon arriving in Brora, they discovered the town's coal mining operations were still in full operation, and as a result, were unable to gain access to the mines. Instead,
7900-474: The ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". It links taxonomic data with images from the collection, to provide a single point of access with information on identification, distribution, traits, conservation, molecular phylogenies and uses. In addition it serves as a backbone for global resources such as World Flora Online . The International Plant Names Index (IPNI) includes information from
8000-414: The understanding of the earth and its longevity in actuality and the organic matter that existed over the earth’s timeline. Paleobotany also succeeded in the hands of German paleontologist Ernst Friedrich von Schlothiem , and Czech nobleman and scholar, Kaspar Maria von Sternberg . As paleobotany is the specification of fossilized plant life and the environment in which they thrived in, paleoecology
8100-576: The work. The book was an instant success, requiring five editions in the first year, and elevated Stopes to national prominence. Married Love was published on 26 March 1918; that day, Stopes was visiting Humphrey Roe, who had just returned with a broken ankle from service during the First World War after his aeroplane crashed. Less than two months later they were married and Stopes had her first opportunity to practise what she preached in her book. The success of Married Love encouraged Stopes to provide
8200-440: The working classes; the Letter was aimed at redressing her bias. On 16 July 1919, Stopes—pregnant and a month overdue—entered a nursing home. Stopes and the doctors clashed over the method of birth—she was not allowed to give birth on her knees. The child was stillborn ; the doctors suggested the incident was due to syphilis , but an examination excluded the possibility. Stopes was furious and said her baby had been murdered. She
8300-446: Was 38 years old. Aylmer Maude , acclaimed writer and Tolstoy expert, was brought into the home of Stopes and Gates in an effort to support their financial needs. While already having a troublesome marriage, Maude's interjection in the household only added more tension to the marriage as Stopes' flirtatious nature caused Gates more jealousy and frustration. Maude and Stopes remained friends long after her separation from Gates in 1914, and
8400-495: Was a serious issue for Roe; after their marriage, he and Stopes planned to open a clinic for poor mothers in London. Margaret Sanger , another birth-control pioneer, had opened a birth control clinic in New York but the police closed it. In 1920, Sanger proposed opening a clinic in London; this encouraged Stopes to act more constructively, but her plan never materialised. Stopes resigned her lectureship at University College London at
8500-426: Was a successful sequel to Married Love . The following year, Stopes published A Letter to Working Mothers on how to have healthy children and avoid weakening pregnancies , a condensed version of Wise Parenthood aimed at the poor. It was a 16-page pamphlet and was to be distributed free of charge. Stopes's intended audience had—until this work—been the middle classes. She had shown little interest in, or respect for,
8600-517: Was abandoned with the St Louis Code , and replaced by "morphotaxa". The situation in the Vienna Code of 2005 was that any plant taxon whose type is a fossil, except diatoms , can be described as a morphotaxon , a particular part of a plant preserved in a particular way. Although the name is always fixed to the type specimen, the circumscription (i.e. range of specimens that may be included within
8700-461: Was accepted by paleobotanists but not formalised within the International Rules of Botanical Nomenclature . Eventually, Thomas (1935) and Jongmans, Halle & Gothan (1935) proposed a set of formal provisions, the essence of which was introduced into the 1952 International Code of Botanical Nomenclature . These early provisions allowed fossils representing particular parts of plants in
8800-507: Was acquainted with many literary figures of the day. She had long-standing correspondences with George Bernard Shaw and Aylmer Maude , and argued with H. G. Wells . Noël Coward wrote a poem about her, and she edited Lord Alfred Douglas ' letters. She unsuccessfully petitioned Neville Chamberlain to arrange for Douglas to receive a civil list pension; the petition was signed by Arthur Quiller-Couch , John Gielgud , Evelyn Waugh and Virginia Woolf , among others. The general secretary of
8900-415: Was an already named fossil-genus for these cupules. If paleobotanists were confident that the type of the ovule fossil-genus and of the cupule fossil-genus could be included in the same genus, then the two names would compete as to being the correct one for the newly emended genus. In general, there would be competing priority whenever plant parts that had been given different names were discovered to belong to
9000-488: Was annulled. During the First World War , Stopes was engaged in studies of coal for the British government, which culminated in the writing of "Monograph on the constitution of coal" with R.V. Wheeler in 1918. The success of Stopes' work on marriage issues and birth control led her to reduce her scholarly work; her last scientific publications were in 1935. According to W. G. Chaloner (2005), "between 1903 and 1935 she published
9100-628: Was born in Edinburgh . Her father, Henry Stopes , was a brewer, engineer, architect and palaeontologist from Colchester . Her mother was Charlotte Carmichael Stopes , a Shakespearean scholar and women's rights campaigner from Edinburgh. At six weeks old, her parents took Stopes from Scotland; the family stayed briefly in Colchester then moved to London, where in 1880 her father bought 28 Cintra Park in Upper Norwood . Both of her parents were members of
9200-438: Was called a successful pioneering effort to introduce the subject to non-scientists. Around the start of her annulment proceedings in 1913, Stopes began to write a book about the way she thought marriage should work. In July 1913, she met Margaret Sanger , who had just given a talk on birth control at a Fabian Society meeting. Stopes showed Sanger her writings and sought her advice about a chapter on contraception. Stopes's book
9300-476: Was contested while showcasing at conferences, but eventually the evidence became sustainable enough that this finding became one of the greatest contributions to the field. Continuing in the vein of coal ball research, Stopes expanded her studies to include those from the Mesozoic era. This represented an exciting new area of study for her, as little evidence of anatomically preserved Mesozoic plants had been found at that time. Seeking advice from other academics in
9400-511: Was finished by the end of 1913. She offered it to Blackie and Son , who declined. Several publishers refused the book because they thought it too controversial. When Binnie Dunlop , secretary of the Malthusian League , introduced her to Humphrey Verdon Roe —Stopes's future second husband—in 1917, she received the boost that helped her publish her book. Roe was a philanthropist interested in birth control; he paid Fifield & Co. to publish
9500-532: Was granted by the Royal Society . In six weeks, Stopes concluded her Brora research, and made arrangements to depart for Japan on 3 July 1907. She spent eighteen months at the Imperial University, Tokyo and explored coal mines on Hokkaido for fossilized plants. As with the Brora study, Stopes failed to locate any Mesozoic coal balls in Japan either, but did manage to discover many important fossils, such as
9600-559: Was ordered to repay the one hundred pounds arising from the previous hearing, and to pay the defendant's costs in relation to the appeals to the Court of Appeal and the House of Lords. The trial had made birth control a public topic and the number of clients visiting the clinic doubled. The Law Lords found in Sutherland's favour (4–1) and, despite the fact that the decision was irrevocable, Stopes wrote to
9700-485: Was published in 1924. The book was not well received ( The Spectator described it as "a panegyric and not a biography") and it may even have been written by Stopes herself. When Stopes blamed Maude for the book's poor sales, he replied: "you so impressed on me the importance of getting the Life out quickly, and I evidently rushed it to the point of scamping it and failed to correct some of the errors in your rough draft." The book
9800-455: Was republished in 1933 as " Marie Stopes Her Work and Her Play ". While the later book included an account of the Stopes v Sutherland libel trial of 1923, questions have been raised about its credibility. For instance, significant aspects of the story of Stopes' visit to Professor McIlroy in disguise and being fitted with a cervical cap (the same device about which McIlroy had been so critical during
9900-424: Was run by midwives and supported by visiting doctors. It offered mothers birth control advice, taught them birth control methods and dispensed Stopes own "Pro-Race" (and "Racial") cervical caps. The free clinic was open to all married women for knowledge about reproductive health. Stopes tried to discover alternatives for families and increase knowledge about birth control and the reproductive system. Options included
10000-405: Was the end of the matter. It was a moral victory for Stopes as the press saw it, and she appealed. On 20 July, the Court of Appeal reversed the previous decision (2–1), awarding the £100 to Stopes. The Catholic community mobilised to support Sutherland, a Catholic, and Stopes publicly campaigned to raise £10,000. Sutherland made a final appeal to the House of Lords on 21 November 1924, and won; Stopes
