to be corrected, together with the corrected form that was intended
to be published. (2) added after the citation of a name to indicate
that the spelling has had to be corrected, sometimes with a reference
to the author(s) making the correction.
cosmogenre: (unoff.) a rank above that of kingdom, designating
independently evolved systems of Life, e.g. cosmogenre Geobiota
includes all Earth’s biota; only one cosomogenre can therefore be
recognized on Earth.
cotype: (1) (obsol.) a syntype (q.v.). (2) (zool., obsol.) any specimen of the
original type material except the holotype; i.e. an isotype or
paratype. (3) (zool., unoff.) any member of a type-series.
countertype: (palaeo. zool., unoff.) of compression fossils, where the rock
or other medium is split open to reveal a mirrored impression of the
fossil; i.e. the opposite half of the holotype; see antitype.
covariant: (cult. pl.) a plant whose characteristics are maintained solely by
regular practices of cultivation such as by pruning or training.
CPN: Committee on Phylogenetic Nomenclature (q.v.).
crickotype: (zool., unoff.) a holotype and only known specimen of a taxon
that has been completely ground up for DNA analysis (!); see
chromotype.
cross: (cult. pl.) to cause to interbreed; the act of hybridization.
crown clade: (phyl.) a clade originating with the most recent common
ancestor of two or more extant species (or organisms); crown clades
are a subset of node-based clades.
crown clade definition: (phyl.) any definition that necessarily ties a name
to a crown clade, e.g. branch- and apomorphy-modified node-based
definitions and standard node-based definitions in which all the
specifiers represent extant species or organisms.
crucifix, [†]: (1) if appearing after the name of an author in a work, the
symbol traditionally indicates that the author died before the work
was published (but is sometimes also used as a footnote marker in
modern works. (2) (zool., obsol.) if appearing by a scientific name
in synonymy, the symbol indicates a misidentification.
cryptic cultivar: (cult. pl.): see cryptic variety.
