mixed gathering: a gathering (q.v.) which comprises more than a single
species or infraspecific taxon.
mixomorpha, [mx.]: (cult. pl., unoff.) a category for the designation of
forms of chimaeras distinguished only by morphological or
histological characters.
mixtospecies, [mixsp.]: (bot., unoff.,) a species resulting from a genetic
change leading to the formation of a sterility barrier between it and
the parent species; it has been proposed to indicate the origin of such
a species from another by using the interpolated abbreviation
"mixsp.", e.g. Pisum arvense mixsp. abyssinicum.
mixture: (cult. pl., unoff.) an assemblage of different lines from a series.

for plants changed in some way.
mongrel combination: a hybrid word composed of elements from two
languages.
monobasic: (zool., unoff.) of a generic name, one with a single included
species at the time of publication; see monotypic.
monocultype: (unoff.) a monosporial (monogenetic or monocytogenetic)
strain of a microorganism derived from the holotype.
monodelphous homonyms: devalidated names (q.v.) taken up by different
post-starting point authors independently but validated with
different nomenclatural types.
monogeneric: of a suprageneric taxon, one including only a single genus.
monogenotype, [monogenotyp]: (1) (zool., unoff.) the single species
included in a monotypical genus at the time of its publication; a
haplotype (q.v.). (2) (zool., unoff.) a type by original fixation.
