138 Terms used in Bionomenclature
nothomorph, [nothomorpha, nm.]: (1) (bot., obsol.) any hybrid variant,
whether F 1 , segregate or backcross derived from the same parent
species forming a taxon of this category. (2) (bot., obsol.) a rankdenoting
term formerly used for a subordinate taxon within a
nothospecies; names published at the rank of nothomorph are treated
as if names of varieties.
nothospecies: (bot.) a hybrid species; i.e. a nothotaxon between two or
more species.
nothotaxon: (bot.) a hybrid taxon; the result of hybridization between two
or more different taxa.
Notification List: (prok.) a compilation into a single list of names first
introduced in the International Journal of Systematic and
Evolutionary Microbiology which is published in issues of that
journal; see also Validation List.
noun phrase: a compound word consisting of a noun combined with
another noun or modifying adjective, the compound being treated as
a noun in apposition (e.g. "capillus-veneris" meaning “hair of
Venus”); if the adjective is the final element in a species-group
name, its ending is determined by the gender of the noun it modifies
(and not by that of the generic name with which the species-group
name is combined).
nova, [n., nov., novus, novum]: new, used when publishing a new
designation for a taxon, whether as new to science or as a new
combination or new name.
nude combination: see naked combination.
numericlature: the use of numbers instead of names to indicate taxa, which
may be arbitrary (e.g. accession numbers) or coded descriptions;
several such systems have been proposed, but none are currently
accepted or in general use.
numerotype: (1) (zool., unoff.) a type specimen only with a collection
number, other data being lost or destroyed; see also ambiguotype.
(2) (unoff.) a type represented by numbers in a character matrix
compared with others by computer analysis.
