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". Unlike graft hybrids, 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 inaccurate for a graft-chimaera. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crataegus
''Crataegus'' (), commonly called hawthorn, quickthorn, thornapple, Voss, E. G. 1985.

Mespilus
''Mespilus'', commonly called medlar, is a 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, Macedonian and Bulgarian regions, and in western parts of Caucasian Georgia. 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 ...

Chamaemespilus
''Chamaemespilus'' is a genus of shrubs in the family Rosaceae. It is monotypic, being represented by the single species ''Chamaemespilus alpina'', commonly known as false medlar or dwarf whitebeam. It is native to the mountains of central and southern Europe, from the Pyrenees east through the Alps to the Carpathians and the Balkans, growing at elevations of up to 2500 m.Blamey, M. & Grey-Wilson, C. (1989). ''Flora of Britain and Northern Europe''. Description ''Chamaemespilus alpina'' is a deciduous shrub growing to 2–3 m tall. The leaves are spirally arranged, oval-elliptic, 3–7 cm long, with an acute apex and a serrated margin; they are green on both sides, without the white felting found on most whitebeams. The flowers are pink, with five forward-pointing petals 5–7 mm long; they are produced in corymbs 3–4 cm diameter. The fruit is an oval red pome 10–13 mm diameter.Rushforth, K. (1999).

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 ( 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 The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN or ICNafp) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all tho ...

Sorbus
''Sorbus'' is a genus of over 100 species of trees and shrubs in the rose family, Rosaceae. Species of ''Sorbus'' ('' s.str.'') are commonly known as rowan or mountain-ash. The genus used to include species commonly known as whitebeam, chequer tree and service tree that are now classified in other genera (see below). The genus ''Sorbus'', as currently circumscribed, includes only the pinnate leaved species of former subgenus ''Sorbus''. ''Sorbus'' is not closely related to the true ash trees which belong to the genus '' Fraxinus'', although the leaves are superficially similar. Genus As treated in its broad sense, the genus was traditionally divided into several subgenera, however, this treatment was found to be paraphyletic, comprising two disparate lineages within the Malinae subtribe. Consequently, each of the former subgenera have since been elevated into genera in their own right, with the genus name ''Sorbus'' retained only for the rowans. Additionally, it was recogni ...

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 worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
