Edmond Gustave Camus
Edmond Gustave Camus (1852 – 22 August 1915) was a French pharmacist and botanist known for his work with orchids. A pharmacist by vocation, he was a resident of L'Isle-Adam, a community near Paris. He was the father of botanist Aimée Antoinette Camus (1879–1965), with whom he collaborated on several projects, and the painter Blanche-Augustine Camus (1881-1968). For a period of time, he served as vice-president of the Société botanique de France. As a taxonomist, he was the binomial authority of many species, most notably within the family Orchidaceae. With Aimée Camus, he described numerous species from the family Salicaceae.

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crataegus
''Crataegus'' (), commonly called hawthorn, quickthorn, thornapple, Voss, E. G. 1985.

The name "hawthorn" was originally applied to the species native to northern Europe, especially the common hawthorn ''C. monogyna'', and the unmodified name is often so used in Britain and Ireland. The name is now also applied to the entire genus and to the related Asian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mespilus
''Mespilus'', commonly called medlar, is a monotypic genus of flowering plants in the family Rosaceae containing the single species ''Mespilus germanica'' of southwest Asia. It is also found in some countries in the Balkans, especially in Albanian regions. A second proposed species, ''Mespilus canescens'', discovered in North America in 1990, proved to be a hybrid between ''M. germanica'' and one or more species of hawthorn, and is properly known as ×'' Crataemespilus canescens''. Plant ''Mespilus'' forms deciduous large shrubs to small trees growing up to tall. The fruit is a matte brown pome. History ''Mespilus germanica'' is apparently native only to southwest Asia and southeastern Europe, i.e. near the Black Sea coast and western Mediterranean, and Asia Minor, as well as the Caucasus and northern Iran, but it has an ancient history of cultivation and wild plants exist in a much wider area; it was grown by the ancient Greeks and Romans, beginning in the second century B ...

Graft-chimera
In horticulture, a graft-chimaera may arise in grafting at the point of contact between rootstock and scion and will have properties intermediate between those of its "parents". A graft-chimaera is not a true hybrid but a mixture of cells, each with the genotype of one of its "parents": it is a chimaera. Hence, the once widely used term "graft-hybrid" is not descriptive; it is now frowned upon. Propagation is by cloning only. In practice graft-chimaeras are not noted for their stability and may easily revert to one of the "parents". Nomenclature Article 21 of the ''ICNCP'' stipulates that a graft-chimaera can be indicated either by * a formula: the names of both "parents", in alphabetical order, joined by the plus sign "+": : ''Crataegus'' + ''Mespilus'' * a name: ** if the "parents" belong to different genera a name may be formed by joining part of one generic name to the whole of the other generic name. This name must not be identical to a generic name published under t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Edward Smith (botanist)
__NOTOC__ Sir James Edward Smith (2 December 1759 – 17 March 1828) was an English botanist and founder of the Linnean Society. Early life and education Smith was born in Norwich in 1759, the son of a wealthy wool merchant. He displayed a precocious interest in the natural world. During the early 1780s he enrolled in the medical course at the University of Edinburgh where he studied chemistry under Joseph Black and natural history under John Walker. He then moved to London in 1783 to continue his studies. Smith was a friend of Sir Joseph Banks, who was offered the entire collection of books, manuscripts and specimens of the Swedish natural historian and botanist Carl Linnaeus following the death of his son Carolus Linnaeus the Younger. Banks declined the purchase, but Smith bought the collection for the bargain price of £1,000. The collection arrived in London in 1784, and in 1785 Smith was elected Fellow of the Royal Society. Academic career Between 1786 and 1788 Smit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maleae
The Maleae (incorrectly Pyreae) are the apple tribe in the rose family, Rosaceae. The group includes a number of plants bearing commercially important fruits, such as apples and pears, while others are cultivated as ornamentals. Older taxonomies separated some of this group as tribe Crataegeae,G. K. Schulze-Menz 1964. ''Reihe Rosales''. in ''A. Engler's Syllabus der Pflanzenfamilien mit besonderer Berücksichtigung der Nutzpflanzen nebst einer Übersicht über die Florenreiche und Florengebiete der Erde'', Gebrüder Borntraeger, Berlin as the Cydonia group (a tentative placement), or some genera were placed in family Quillajaceae. The tribe consists exclusively of shrubs and small trees. Most have pomes, a type of accessory fruit that does not occur in other Rosaceae. All except ''Vauquelinia'' (with 15 chromosomes) have a basal haploid chromosome count of 17, instead of 7, 8, or 9 as in the other Rosaceae. There are approximately 28 genera that contain about 1100 species worldw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Nothogenera
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability ...
