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] |

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 ...

Chamaemespilus
''Sorbus chamaemespilus'', the false medlar or dwarf whitebeam, is a species of ''Sorbus'' native to the mountains of central and southern Europe, from the Pyrenees east through the Alps to the Carpathian Mountains, Carpathians and the Balkans, growing at altitudes of up to 2500 m.Blamey, M. & Grey-Wilson, C.

Segregate (taxonomy)
In taxonomy, a segregate, or a segregate taxon is created when a taxon is split off from another taxon. This other taxon will be better known, usually bigger, and will continue to exist, even after the segregate taxon has been split off. A segregate will be either new or ephemeral: there is a tendency for taxonomists to disagree on segregates, and later workers often reunite a segregate with the 'mother' taxon. If a segregate is generally accepted as a 'good' taxon it ceases to be a segregate. Thus, this is a way of indicating change in the taxonomic status. It should not be confused with, for example, the subdivision of a genus into subgenera. :For example, the genus ''Alsobia'' is a ''segregate'' from the genus ''Episcia''; The genera ''Filipendula'' and ''Aruncus'' are segregates from the genus ''Spiraea''.

Subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostylis'', ...

Sorbus
''Sorbus'' is a genus of over 100 species of trees and shrubs in the rose family, Rosaceae. Species of ''Sorbus'' (''s.l.'') are commonly known as whitebeam, rowan ( mountain-ash) and service tree. The exact number of species is disputed depending on the circumscription of the genus, and also due to the number of apomictic microspecies, which some treat as distinct species, but others group in a smaller number of variable species.

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.
