87 The naming of organisms (and plant communities)
heautotype: (palaeo. zool., obsol.): a specimen figured by an author in an
illustration of a species or subspecies which had previously been
described by that author and compared with the type or cotype; a
kind of plesiotype; see also autotype, hypotype.
heberotype: (zool. unoff.) a unique type specimen that has been used for
molecular analysis that failed and is only left with a barcode label to
identify it (!).
hectographing: the making of copies of text and figures from a prepared
gelatine surface to which the original has been transferred.
hemihomonymy: (zool.) the situation where the names of a high-level
uninomen and a low-level uninomen are identical (e.g. the name of
an order and a genus), even when the high-level taxon uninomen is
not typified by similarly spelt genus-level name (e.g. family-group
names and genus-level names ending in "-ina").
hemitype: (zool., unoff.) a type represented by only half of its original
body.
herbarium, [pl. herbaria; hb., Hb., herb., Herb.]: (1) a collection of dried
botanical specimens; see also fungarium, mycarium. (2) the building
in which such a collection is housed.
heterodefinitional: (phyl.) based on different phylogenetic definitions; see
synonym.
heterogen: a variable group of organisms arising as hybrids, sports or other
mutations.
heterogeneous: a taxon which as circumscribed includes two or more
elements which are considered to belong to one or more other taxa.
heterotype: (zool., unoff.) a type derived by combining the characters of
two or more different species.
heterotypic: differing from the type.
heterotypic synonym: (bio., bot.) a name based on a different type from
that of the accepted name of taxon; a subjective synonym in zool.
and prok.; see also taxonomic synonym; syntaxonomic synonym.
heterotypical: (zool., unoff.) of a genus, one including several generically
unrelated species.
