Crataegus Rhipidophylla
''Crataegus rhipidophylla'' is a species of hawthorn which occurs naturally from southern Scandinavia and the Baltic region to France, the Balkan Peninsula, Turkey, Caucasia, and Ukraine. It is poorly known as a landscape and garden plant, but seems to have potential for those uses. Compared to ''Crataegus monogyna'', ''C. rhipidophylla'' has larger flowers, larger and more colourful fruits, and more decorative foliage. It has a more or less dome-shaped crown, and it is more tolerant of shade than ''C. monogyna''. Description ''Crataegus rhipidophylla'' is a shrub or tree which can grow to tall. Its stout thorns can be up to 1.5 cm long. Leaf blades are dark green, with 2-4 pairs of acute or subacuminate lobes. A helpful characteristic trait for identification is the finely serrated lobe margin. This can help distinguish ''C. rhipidophylla'' from ''C. monogyna'' which has irregularly serrated lobe margins, with more or less coarse teeth. The basal lobes of flowering shoot ...

Michel Gandoger
Abbé Jean Michel Gandoger (10 May 1850 – 4 October 1926), was a French botanist and mycologist. He was born in Arnas, Rhône, Arnas, the son of a wealthy vineyard owner in the Beaujolais region. Although he took holy orders at the age of 26, he devoted his life to the study of botany, specializing in the genus ''Rose, Rosa''. He travelled throughout the Mediterranean, notably Crete, Spain, Portugal, and Algeria, amassing a herbarium of over 800,000 specimens, now kept at the Jardin botanique de Lyon. However, he is notorious for having published thousands of plant species that are no longer accepted. He died at Arnas in 1926. Father J B Charbonnel published an obituary in the Bulletin de la Societe botanique de France (1927, Vol. 74, 3–11), listing Gandoger's many publications. Plants with the specific epithet of ''gandogeri'' are named after him, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stigma (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals ( biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and sle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crataegus × Macrocarpa
''Crataegus'' × ''macrocarpa'', is a hybrid between two species of '' Crataegus'' (hawthorn), '' C. laevigata'' and '' C. rhipidophylla'', both in series '' Crataegus''. A chemotaxonomic investigation comparing flavonoid patterns in ''C.'' × ''macrocarpa'' and its putative parent species corroborated their supposed relationship. It is sometimes confused with '' C. × media'', the hybrid between '' C. monogyna'' and '' C. laevigata''. Under the rules of botanical nomenclature the name ''C.'' × ''macrocarpa'' covers all intermediate forms between the two parent species, including backcrosses. References macrocarpa ''Hesperocyparis macrocarpa'' is a coniferous tree. It is commonly known as the Monterey cypress and is one of several species of cypress trees endemic to California.

Conserved Name
A conserved name or ''nomen conservandum'' (plural ''nomina conservanda'', abbreviated as ''nom. cons.'') is a scientific name that has specific nomenclatural protection. That is, the name is retained, even though it violates one or more rules which would otherwise prevent it from being legitimate. ''Nomen conservandum'' is a Latin term, meaning "a name to be conserved". The terms are often used interchangeably, such as by the ''International Code of Nomenclature for Algae, Fungi, and Plants'' (ICN), while the ''International Code of Zoological Nomenclature'' favours the term "''conserved name''". The process for conserving botanical names is different from that for zoological names. Under the botanical code, names may also be "suppressed", ''nomen rejiciendum'' (plural ''nomina rejicienda'' or ''nomina utique rejicienda'', abbreviated as ''nom. rej.''), or rejected in favour of a particular conserved name, and combinations based on a suppressed name are also listed as “''nom. re ...

Liergues
Liergues () is a former commune in the Rhône department in eastern France. On 1 January 2017, it was merged into the new commune Porte des Pierres Dorées. Its population was 2,185 in 2019. Geography The commune is crossed from south to north by the Merloup (or Merloux) which has its source in Theizé and flows into the Morgon, a tributary of the Saône (and therefore sub-tributary of the Rhône) at Gleizé.

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrena
A pyrena or pyrene (commonly called a "pit" or "stone") is the fruitstone within a drupe or drupelet produced by the ossification of the endocarp or lining of the fruit. It consists of a hard endocarp tissue surrounding one or more seeds (also called the "kernel"). The hardened endocarp which constitutes the pyrene provides a protective physical barrier around the seed, shielding it from pathogens and herbivory. While many drupes are monopyrenous, containing only one pyrene, pome-type fruit with a hard, stony (rather than leathery) endocarp are typically polypyrenous drupes, containing multiple pyrenes. Development The hardening of the endocarp of a developing drupe occurs via secondary cell wall formation and lignification. The biopolymer lignin, also found in wood, provides a structure within secondary cell walls which supports the polymerisation of cellulose and hemicellulose; together these polymers provide the endocarp with tensile strength and stiffness. Further harden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Victor Von Janka
Viktor Janka von Bulcs, often shortened to ''Viktor Janka'' (24 December 1837 in Vienna - 9 August 1890 in Budapest) was an Austrian military officer and botanist. He worked as the officer of a Cuirassier regiment (armoured cavalry soldiers) for the Imperial Austrian Army until 1870. He was then named curator of the botanical department of the Budapest National Museum. He ceased working for the museum in 1889 and died one year later in the same city. Janka had collected many botanical specimens throughout the Austro-Hungarian Empire and his types are housed in the herbarium of the Babeș-Bolyai University in Romania. He discovered and described several plant species, including the Hungarian crocus ('' Colchicum hungaricum''). The monotypic relict genus ''Jankaea'', the orchid species ''Himantoglossum jankae ''Himantoglossum'' is a genus of orchids native to the Canary Islands, Europe, southwest Asia and northern Africa.

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Hypanthium
In angiosperms, a hypanthium or floral cup is a structure where basal portions of the calyx, the corolla, and the stamens form a cup-shaped tube. It is sometimes called a floral tube, a term that is also used for corolla tube and calyx tube. It often contains the nectaries of the plant. It is present in many plant families, although varies in structural dimensions and appearance. This differentiation between the hypanthium in particular species is useful for identification. Some geometric forms are obconic shapes as in toyon, whereas some are saucer-shaped as in '' Mitella caulescens''. Its presence is diagnostic of many families, including the Rosaceae, Grossulariaceae, and Fabaceae. In some cases, it can be so deep, with such a narrow top, that the flower can appear to have an inferior ovary - the ovary is below the other attached floral parts. The hypanthium is known by different common names in differing species. In the eucalypts, it is referred to as the ''gum nut''; ...
