178 Terms used in Bionomenclature
not constitute publication for purposes of zoological nomenclature;
see also author's extra, offprint, preprint.
sequotype: (zool., unoff.) the specimen immediately following a holotype
in the author's collection sequence.
ser.: series (q.v.).
serial: a publication issued at regular or irregular intervals; see journal.
series: (1) (bot.) a category of taxa intermediate in rank between section
and species. (2) (bot., obsol.) an infrageneric category formally used
by some workers using names based on the included species. (3)
(cult. pl.) in seed marketing, a number of cultivars based upon a
certain ideotype and differing from each other usually only in one
character, normally flower colour. (4) (cult. pl., unoff.) a category
for the designation of a group of closely related proles (q.v.), or of a
group of related species forming a conspecies (q.v.). (5) (zool.,
unoff.) a rank between subkingdom and phylum.
series mixture: (cult. pl.) in seed marketing, a mixture of cultivars from a
series.
serological type: a serotype (q.v.).
serotype: (1) (prok.) a variant of a species or subspecies distinguished from
other such variants of the same species or subspecies on the basis of
its antigenic structure; a serological type. (2) (vir.) a strain or group
of strains, particles of which react well with one or more antibody
preparations and which are distinguishable from other strains or
groups of strains by this reactivity.
serovar: (prok.) an infrasubspecific strain of a species distinguished from
other such variants by antigeneric characteristics; a serotype.
Session, Nomenclature: see Nomenclature Session.
seu: either, or.
sexual hybrid: see hybrid, mechanical hybrid.
sexual type: (zool., unoff.) see locality type.
s-g., [s-gg.]: see subgenus.
shared organ species: see form species.
