Having but one type; containing but one representative; as, a monotypic genus, which contains but one species.

The only representative of its group, as a single species constituting a genus.

A genus with one species or a family with one genus. In general, applied to any taxon with only one immediately subordinate taxon of one of the principal ranks. (McVaugh et al. 1968. Regn. Veget. 56: 17; ICBN). Comment: Although a nomenclatural term, the word has little to do with the typification process, but only the state of various taxa after their description, and often temporary at that. Monotype has been interpreted (Korf and Rogers. 1967. Taxon 16: 20) as an implied holotype.
