Botanists with author abbreviations

Antoine-Fortuné Marion (10 October 1846 – 22 January 1900) was a French naturalist with interests in geology, zoology, and botany. He was also a competent amateur painter.
A school friend of Paul Cézanne's in Aix-en-Provence, Marion went on to become professor and director of the Natural History Museum in Marseille. Cézanne painted his portrait in 1866–1867 at the Bastide du Jas de Bouffan.
He received his higher education in Marseille, earning his arts and letters degree in 1866 and his degree in sciences in 1868. In 1878 he opened a marine laboratory with financial assistance provided by the city of Marseille, which led in 1882 to the building of the Marine Station of Endoume. In 1880 he became director of the Muséum d’histoire naturelle de Marseille.He was a good friend of Gaston de Saporta, with whom he collaborated on works in the field of botany. As a zoologist, his research included studies of segmented marine worms, free-living roundworms of the Mediterranean, nemerteans, rotifers, zoantharians, alcyonarians, parasites that affected crustaceans and investigations of the class Enteropneusta. As a result of his work in the fight against Phylloxera (an aphid-like pest), he was given awards by the French and foreign governments.He was a founder of the publication "Annales du Musée d'histoire naturelle de Marseille".His painting The Village Church now belongs to the Fitzwilliam Museum.

René Charles Joseph Ernest Maire (29 May 1878, Lons-le-Saunier – 24 November 1949) was a French botanist and mycologist. His major work was the Flore de l'Afrique du Nord in 16 volumes published posthumously in 1953. He collected plants from Algeria, Morocco, France, and Mali for the herbarium of the National Botanic Garden of Belgium.

Jean-Henri Magne (15 July 1804, Sauveterre-de-Rouergue – 27 August 1885) was a French veterinarian.

During his career, he worked as a professor at the École royale vétérinaire de Lyon and at the École nationale vétérinaire d'Alfort, where from 1846, he served as director.In 1836 he became a member of the Société linnéenne de Lyon, serving as its president in 1841/42.

Louis Charles Émile Lortet (22 August 1836 – 26 December 1909) was a French physician, botanist, zoologist and Egyptologist who was a native of Oullins.
He earned his medical doctorate in 1861, and his degree in natural sciences in 1867. He served as premier doyen at the Faculty of Medicine of Lyon from 1877 until 1906. Also, from 1868 to 1909, he was director of the natural history museum in Lyon.
Lortet is remembered for his scientific and zoological expeditions to the Middle East (Syria, Lebanon and Egypt). He performed studies of mummified animals from the New Kingdom of ancient Egypt, and in 1880 took part in an excavation of a Phoenician necropolis.
Lortet was a member of numerous scientific societies, such as the Société de géographie de Lyon, being a founding member in 1858. Species with the epithet of lorteti are named in his honor; an example being the pufferfish species Carinotetraodon lorteti.

Henri Lecoq (18 April 1802 – 4 August 1871) was a French botanist. Charles Darwin mentioned this name in 1859 in the preface of his famous book On The Origin of Species as a believer in the modification of species. Darwin wrote:
A well-known French botanist, M. Lecoq, writes in 1854 ('Etudes sur Géograph. Bot.,' tom. i. p. 250), 'On voit que nos recherches sur la fixité ou la variation de l'espèce, nous conduisent directement aux idées émises, par deux hommes justement célèbres, Geoffroy Saint-Hilaire et Goethe.' Some other passages scattered through M. Lecoq's large work, make it a little doubtful how far he extends his views on the modification of species.
The work referenced by Darwin is Lecoq's "Étude de la Géographie Botanique de l’Europe", published in 1854.
A number of plants carry the name of Lecoq in their descriptive names (see IPNI search). Also in 1829, botanist DC. published Lecokia, a monotypic genus of flowering plants belonging to the family Apiaceae with its name honouring him.In addition a museum in his home town of Clermont Ferrand (France) is named after him.

Jean Kickx (17 January 1803, Brussels – 1864) was a Belgian botanist. His father, also known as Jean Kickx (1775–1831) was a botanist and mineralogist; his son Jean Jacques Kickx (1842–1887) was a professor of botany at the University of Ghent.
In 1830 he obtained his PhD at Leuven, later serving as a professor of botany in Brussels (1831–1835) and at the University of Ghent (1835–1864). He was a co-founder of the Société royale de botanique de Belgique.The mycological genus Kickxella (order Kickxellales) was named in his honor by Eugène Coumans.

Henri Lucien Jumelle (25 November 1866 in Dreux, Eure-et-Loir Department, France – 6 December 1935 in Marseille, Bouches-du-Rhône Department, France) was a French botanist.From 1887 to 1894, he worked as a plant physiologist at the Faculté des Sciences in Paris. Afterwards, he was a professor of botany at the Faculté des Sciences in Marseille (1894-1935). From 1898 to 1916, he was assistant director, then director of the Musée colonial et du Jardin botanique in Marseille.He held a deep interest in applied botany, publishing numerous treatises on the agricultural aspects of various plants. During his career, he worked closely with botanist Joseph Alfred Perrier de la Bâthie, who sent him botanical material from Madagascar. As a taxonomist, he circumscribed many new species native to Madagascar.From 1922 to 1935, he was a correspondent-member of the Académie des Sciences (botanical section).

Louis-Félix Henneguy (18 March 1850 – 16 January 1928) was a French zoologist and embryologist born in Paris.
In 1875, he received his medical doctorate from the University of Montpellier with a dissertation on the physiological action of poisons, Étude physiologique sur l'action des poisons. In 1883 he obtained his agrégation with Les lichens utiles, a thesis on useful lichens.
During his career he was a professor of comparative embryology at the Collège de France (1900–28), and a member of the Académie de Médecine, the Académie d'Agriculture and the Académie des sciences (1908–28). From 1894 he was director of the journal, Archives d'anatomie microscopique.
He is known for his extensive research of phylloxera, publishing a number of papers on means of destroying its eggs during the winter (1885, 1887–88). Also he performed studies on the natural history of the apple blossom weevil, proposing methods for its eradication (1891). On behalf of the Marine Fisheries Advisory Committee, he did reviews involving the sale and consumption of mussels throughout the year.
With Hungarian neuroanatomist, Mihály Lenhossék (1863–1937), the "Henneguy–Lenhossek theory" is named, which states the claim that mitotic centrioles and ciliary basal kinetosomes are fundamentally the same structure.As a taxonomist he circumscribed the apicomplexan genus Rhytidocystis, and the protozoan genera Thelohania and Fabrea. The genus Henneguya Thélohan, 1892 is named after him, as are the species Apherusa henneguyi Chevreux & Fage, 1925 and Ectinosoma henneguyi Labbé, 1926.In 1903 he was appointed president of the Société entomologique de France.

Lucien Leon Hauman-Merck (8 July 1880, in Ixelles – 16 September 1965, in Brussels) was a Belgian botanist, who studied and collected plants in South America and Africa.
He received his education in Gembloux, and afterwards relocated to Argentina, where he obtained a position in the department of agronomy and veterinary medicine at the University of Buenos Aires. From 1904 to 1925 he taught classes in botany, plant pathology and agricultural microbiology at the university. In 1910 he laid the foundations for its botanical garden.In Argentina he conducted important phytogeographical research, and he also performed plant collection duties that involved excursions to Paraguay, Chile and Uruguay. In 1927 he returned to Europe, where from 1928 to 1949, he served as a professor of botany at the Free University of Brussels. During this time period, he studied African flora, about which, he collected numerous plants in the Belgian Congo. In 1949 he returned to Argentina as an honorary professor at the University of Buenos Aires. The "Jardín Botánico Lucien Hauman" at the university is named in his honor.The genera Haumania (J.Léonard, 1949) and Haumaniastrum (P.A.Duvign. et Plancke, 1959) commemorate his name, as do species with the epithet of haumanii.

Carl (or Karl) Otto Harz (28 November 1842 in Gammertingen – 5 December 1906 in Munich) was a German mycologist, pharmacist and botanist.
After spending time as an intern in several pharmacies, he studied botany at the University of Berlin. Later, he relocated to Munich, where he served as a lecturer at the Technische Universität München (from 1873) and at the Tierärztlichen Hochschule (from 1874). In 1880 he was appointed professor of botany and pharmacognosy at the Tierärztlichen Hochschule.In 1877, with pathologist Otto Bollinger, he conducted early studies of actinomycosis in cattle, and is credited for naming the causal agent Actinomyces bovis. From his observations, he believed the culprit to be a mould, related to the genera Botrytis or Monosporium.As a taxonomist, he circumscribed a number of varieties from the species Cucurbita pepo. His name is associated with the following mycological genera:

Harzia (family Ceratostomataceae), named by Julien Noël Costantin (1888).
Harziella (family Chaetomiaceae), named by Otto Kuntze (1891).
