nomenclatural type

no·men·cla·tur·al type

the constituent element of a taxon to which the name of the taxon is permanently attached; the type of a species is preferably a strain (in special cases it may be a description, a preserved specimen or preparation, or an illustration); the type of a genus is a species; and the type of an order, family, or tribe is the genus on whose name the name of the higher taxon is based.

(1992) have not explicitly assigned the nomenclatural type, only one element (releve) is available for typification in their paper, hence this releve becomes automatically the holotype.
alba (L.) Vahl, is not apparent from the name Rhynchospora (for discussions of the nomenclatural type method, see Cook, 1898, 1900; Hitchcock, 1905, 1925; Lawrence, 1951; Steam, 1957; Farber, 1976).
Another basic component of our current nomenclatural system--the nomenclatural type method--was also not followed by Linnaeus (Hitchcock, 1925; Steam, 1957).
44 -even if they no mentioned it--proposed the new name Zygophyllo fontanesii-Sarcocornietum perennis whose nomenclatural type is the same as that of Sarcocornietum perennis M.
This name was proposed for rejection as nomen ambiguum since it has often been used (mostly accompanied the erroneous author citation 'Braun-Blanquet 1936') in a sense that excludes its nomenclatural type (DENGLER & al., 2006).
mamillata are known from Europe under invalid name Eleocharitetum mamillatae Passarge 1999, because original diagnosis doesn't contain any releve and no one earlier published releve is indicated as a nomenclatural type (PASSARGE, 1999).
The authors selected nomenclature types for all four subassociations of the ' Diantho humilis-Velesietum' (see fine printed text below the table on page 96), however, they failed to assign unequivocally the nomenclatural type of the association.
As no nomenclatural type was designated for the Cirsietalia chamaepeuces either by Horvat & al.
The name of this alliance (as suggested in the original diagnosis by Karpov, 2001: 110) is in the contradiction with Article 10b of the IPCN since Artemisia pauciflora is invariably the dominating species (see the original diagnosis of the nomenclatural type of this alliance).
Matevski & Carni (2001) suggested the alliance Euphorbio taurinensis-Geranion lucidi to encompass short-lived nitrophilous fringe vegetation of Macedonia (Republic of Macedonia and Greece), but failed to provide a nomenclatural type, which rendered the description invalid according to Art.
What was lacking in the Linnaean system of nomenclature until early in the nineteenth century was a consistent system for determining how a name should be applied--the fixation of concept, what we now refer to as "typification." The method chosen in all branches of biology was that of nomenclatural types. With the exception of some of the most highly ranked taxa, under this system groupings above the species-group level derive their names--and consequently concepts--from genera.
