not validly published (bot.); see also provisional name, question
mark.
addition sign, [+]: (1) (cult. pl.) the ideograph used to indicate a graftchimaera,
either as a part of a formula (e.g. Crataegus monogyna +
Mesplius germanica), or in front of an abbreviated name (e.g. +
Crataemespilus gillottii). (2) (bot., unoff.) also used in a proposed
citation system for addospecies (q.v.).
addospecies, [adsp.]: (bot., unoff.) a proposed system for indicating the
parents of a hybrid species, in which their names follow the notation
"adsp."and are linked by an addition sign, e.g. Galeopsis tetrahit
adsp. pubescens + speciosa.
adelfotype: (zool., unoff.) a topotype (q.v.) obtained by the original
collector of the taxon; i.e. specimens from the type locality collected
by the original collector, but not of the original type-series.
admissible name: (1) of the use of a name or epithet, in accordance with
the provisions of the Code. (2) (bot.) of a name, in a form that could
permit it to be validly published (e.g. a tautonym is not admissible in
bot.); (3) (cult. pl.) an unpublished name that is in a form that it
would enable it to be established.
admixture: (1) (bot.) used of components (especially minor ingredients) of
a gathering that represent a taxon other than that intended by the
collector, and do not preclude the gathering, or part thereof, being a
type specimen, the admixture being disregarded; i.e. elements
representing a taxon other than those belonging to the type of a
name. (2) (bot., unoff.) a gathering or collection an author
considered to be a single species or infraspecific taxon, but which
was later shown to contain representatives of more than one such
taxon; a mixed gathering (q.v.).
adopt: (1) to use a particular name, designation or epithet to denote a
particular taxon. (2) frequently used when the author takes up an
already existing name in preference to one that cannot be adopted as
a correct name for the taxon. (3) (bot., zool.) to use a designation
that is not a validly published name or an unavailable name in a way
which establishes it as a new name with its own authorship and date;
see also accepted name.
