  • autonym. An automatically generated infrageneric or infraspecific name.


  • comb. inval. (combinatio invalidum). A combination not validly published according to ICBN.

  • nom. cons. (nomen conservandum). (1) A name of a family, genus or species [or infraspecies] ruled as legitimate and with precedence over other specified names even though it may have been illegitimate when published or lack priority (Art. 14.1-14.7). (2) A name for which its type, orthography, or gender has been fixed by the conservation process (Art. 14.1, 14.9-14.11).

Virus classification[edit]

Virus species definition[edit]

Species form the basis for any biological classification system. The ICTV had adopted the principle that a virus species is a polythetic class of viruses that constitutes a replicating lineage and occupies a particular ecological niche.[citation needed] In July 2013, the ICTV definition of species changed to state: "A species is a monophyletic group of viruses whose properties can be distinguished from those of other species by multiple criteria."[2]

ICTV classification[edit]

The International Committee on Taxonomy of Viruses began to devise and implement rules for the naming and classification of viruses early in the 1970s, an effort that continues to the present. The ICTV is the only body charged by the International Union of Microbiological Societies with the task of developing, refining, and maintaining a universal virus taxonomy.

The system shares many features with the classification system of cellular organisms, such as taxon structure. However, this system of nomenclature differs from other taxonomic codes on several points. A minor point is that names of orders and families are italicized,[3] unlike in the International Code of Nomenclature for algae, fungi, and plants and International Code of Zoological Nomenclature.

Viral classification starts at the level of order and continues as follows, with the taxon suffixes given in italics:

Parasitic plant terms[edit]

Parasitic plants are characterized as follows:

    1. obligate parasite, obligate – a parasite that cannot complete its life cycle without a host.
    2. facultative parasite, facultative – a parasite that can complete its life cycle independent of a host.
  1. Attachment
    1. stem parasite – a parasite that attaches to the host stem.
    2. root parasite – a parasite that attaches to the host root.
  2. Holoparasite Hyobanche sanguinea, Richtersfeld, Namaqualand, northern cape, South Africa
    1. holoparasite – a plant that is completely parasitic on other plants and has virtually no chlorophyll.
    2. hemiparasite – a plant that is parasitic under natural conditions and is also photosynthetic to some degree. Hemiparasites may just obtain water and mineral nutrients from the host plant. Many obtain at least part of their organic nutrients from the host as well.

For hemiparasites, one from each of the three sets of terms can be applied to the same species, e.g.

   Nuytsia floribunda (Western Australian Christmas tree) is an obligate root hemiparasite.
   Rhinanthus (e.g. Yellow rattle) is a facultative root hemiparasite.
   Mistletoe is an obligate stem hemiparasite.

Holoparasites are always obligate so only two terms are needed, e.g.

   Dodder is a stem holoparasite.
   Hydnora spp. are root holoparasites.

Plants usually considered holoparasites include broomrape, dodder, Rafflesia, and Hydnoraceae. Plants usually considered hemiparasites include Castilleja, mistletoe, Western Australian Christmas tree and yellow rattle.
