Multiple Parts (original Plus Revising Author/s)

In many cases the author citation will consist of two parts, the first in parentheses, e.g.:

  • Helianthemum coridifolium (Vill.) Cout.

This form of author citation indicates that the epithet was originally published in another genus (in this case as Cistus coridifolius) by the first author, Dominique Villars (indicated by the enclosing parentheses), but moved to the present genus Helianthemum by the second (revising) author (António Coutinho). Alternatively, the revising author changed the rank of the taxon, for example raising it from subspecies to species (or vice versa), from subgenus to Section, etc. (Again, the latter is in contrast to the situation in zoology, where no authorship change is recognized within family-group, genus-group, and species-group names, thus a change from subspecies to species, or subgenus to genus, is not associated with any change in cited authorship).

As indicated above, either the original or the revising author may be of more complex form, as per the following examples from the same genus:

  • Helianthemum sect. Atlanthemum (Raynaud) G.López, Ortega Oliv. & Romero García
  • Helianthemum apenninum Mill. subsp. rothmaleri (Villar ex Rothm.) M.Mayor & Fern.Benito
  • Helianthemum conquense (Borja & Rivas Goday ex G.López) Mateo & V.J.Arán Resó

Famous quotes containing the words multiple and/or parts:

    There is a continual exchange of ideas between all minds of a generation. Journalists, popular novelists, illustrators, and cartoonists adapt the truths discovered by the powerful intellects for the multitude. It is like a spiritual flood, like a gush that pours into multiple cascades until it forms the great moving sheet of water that stands for the mentality of a period.
    Auguste Rodin (1849–1917)

    We have seen that men are learning that work, productivity, and marriage may be very important parts of life, but they are not its whole cloth. The rest of the fabric is made of nurturing relationships, especially those with children—relationships which are intimate, trusting, humane, complex, and full of care.
    Kyle D. Pruett (20th century)
