1939 R. Melville in Proc. Linn. Soc. 151 158 I therefore propose the term nothomorph (nothomorphus = hybrid form) for all hybrid forms of sexual origin, whether F₁ segregates or back-crosses.

1953 Rep. Proc. 7th Internat. Bot. Congr. 1950 544/2 These forms are recognized as nothomorphs; when desirable they may be designated by an epithet preceded by the binary name of the group and the term nothomorph.

1963 P. H. Davis & V. H. Heywood Princ. Angiosperm Taxon. xiv. 482 The term nothomorph can be used to distinguish different derivatives of hybridisation between the same species.

1979 Watsonia 12 251 This international volte-face..compels another deplorable name change... E[rica] x stuartii must be used for all the nothomorphs, or cultivars, of E. mackaiana x E. tetralix.

1991 C. Stace New Flora Brit. Isles 680 Mints... Taxonomically difficult due to..widespread hybridization, and the clonal propagation of mutants and nothomorphs by the strongly developed rhizomes.
