disclaimer: (zool.) a statement in a work, by an author, editor, or publisher,
that either the entire work or all specified names and nomenclatural
actions are to be excluded for purposes of zoological nomenclature.
discordant elements: elements on which a name was based which are now
considered to belong to two or more distinct taxa; in (bot.) such
names were ruled as illegitimate until 1975.
dissectoype: (zool., unoff.) a completely dissected type; see also
crickotype.
diverged variety: (cult. pl.) a cultivar that is derived from an earlier selfpollinated
cultivar and which no longer meets criteria for a DUS test
(q.v.).
divide: (unoff.) to remove as a separate taxon an element from within the
circumscription of a previously recognized taxon; to segregate
(q.v.).
divinotype: (1) (zool., unoff.) a new species found and collected alive
already bearing a holotype label (!). (2) (zool., unoff.) a type only
seen during séances (!).
division, [divisio]: (1) a taxon at the rank of division; in (bot.) one of two
terms for the same rank, the other being phylum (q.v.); the highest
rank of the principal categories of taxa below kingdom; a phylum
(the term preferred in overall biological classifications). (2) (zool.) a
rank that if treated as a division of a genus or subgenus is deemed to
be of subgeneric rank for the purposes of nomenclature. (3) (cult.
pl., unoff.) a taxoid for the designation of a group of closely related
cycles (q.v.).
divisum: (bot., unoff., obsol.) proposed as a designation for a clone (q.v.).
domain: a taxonomic rank above that of kingdom; cfr empire,
superkingdom.
domesticated animals: (zool.) animals distinguished from wild progenitors
by characters resulting from the selective actions (deliberate or not)
of humans.
dorsotype: (zool., unoff.) a type specimen mounted in such a way that only
its dorsal aspect is visible for study (!).
