133 The naming of organisms (and plant communities)
nomen non rite publicatum, [nom. non rite publ.]: (unoff,) a name not
properly published; sometimes used in citations of synonyms to
indicate a name that has been effectively but not validly published.
nomen novum, [nom. nov.]: a new name (q.v.).
nomen nudum, [nomen nud.]: a naked name (q.v.).
nomen oblitum, [nom. oblit.]: a forgotten name (q.v.).
nomen oppressum, [nom. oppr.]: (bot., unoff.) a name published in a
suppressed work (q.v.) and at a rank specified therein and
consequently treated as not validly published.
nomen periculosum, [nom. peric.]: a perilous name (q.v.).
nomen perplexum, [nom. perplex.]: a perplexing name (q.v.).
nomen protectum, [nom. prot.]: a protected name (q.v.).
nomen provisorium, [nom. provis.]: a provisional name (q.v.).
nomen reclitum, [nom. recl.]: a revived name (q.v.).
nomen rejiciendum, [nom. rej.]: a rejected name (q.v.).
nomen rejiciendum propositum, [nom. rej. prop.]: (bot.) a name
proposed for rejection under the Code but awaiting ratification
either by a Committee or by a subsequent International Botanical
Congress; see conservation, rejected name.
nomen revictum, [nom. rev.]: a revived name (q.v.).
nomen sed non planta: (bot., obsol.) the name but not the plant; formerly
used in citations of synonyms to indicate cases where an author
introducing a new combination or new name applied the name to a
taxon other than that to which the type of the basionym belongs, i.e.
a method of indicating a misapplied name.
nomen seminudum: a semi-naked name; see nomen subnudum.
nomen subnudum: (bot., unoff.) a name with limited or unusual
descriptive information provided in the protologue which is not
sufficiently diagnostic to permit its recognition apart from others
(e.g. a tall plant with white flowers) and so raises doubts as to its
valid publication..
