193 The naming of organisms (and plant communities)<br />

sustaining specimen: (zool., unoff.) an auxiliary type (q.v.).<br />

symbiotype: (zool., unoff.) the host specimen from which a new parasitic<br />

or mutualistic taxon was described.<br />

symbol: (1) (not nomenclatural) a character or mark used to represent<br />

something; an ideograph (q.v.). (2) (cult. pl.) a device which is<br />

appended to a name, which is in itself no part of that name, yet<br />

which provides extra information about the taxon concerned.<br />

symphytocoenological unit: (phyt.) a vegetation complex of some kind;<br />

such units are not considered as syntaxa.<br />

syn., [synonymum]: a synonym (q.v.); often used in the abbreviated form<br />

before a name to indicate it is a synonym of the name properly to be<br />

used for the taxon concerned.<br />

synanamorph: (mycol.) one of two or more different anamorphs (q.v.) that<br />

are part of the same holomorph (q.v.).<br />

synapomorphy: (phyl.) a shared, derived character state; a shared, derived<br />

character state inherited from a common ancestor that possessed that<br />

state; a shared, independently derived character state is not<br />

considered to be a synapomorphy in the sense the term is used in the<br />

PhyloCode.<br />

syncultype: (obsol.) any strain of a microorganism cultivated by the author<br />

of the taxon and quoted in the original description when a holotype<br />

has not been selected.<br />

syndiagnostic: (obsol.) of groups formed by Linnaean diagnoses, as<br />

opposed to ones characterized by breeding freely (syngamic), in a<br />

privative fashion (asyngamic), or breeding from a common parent<br />

(epigony).<br />

synisonym: one of two or more names having the same basionym; see<br />

nomenclatural synonym.<br />

synonym, [synonynum, syn.]: (1) (zool.) each of two or more names of the<br />

same rank used to denote the same taxonomic taxon. (2) (bot., cult.<br />

pl.) a name considered to apply to the same taxon as the accepted<br />

name. (3) (phyl.) a name that is spelled differently than another<br />

name that refers to the same taxon; in the case of clade names,<br />

synonyms may be homodefinitional or heterodefinitional (q.v.). (4)
