APPENDIX I
NAMES OF HYBRIDS

Article H.11

H.11.1. The name of a nothospecies of which the postulated or known parent species belong to different genera is a combination of a nothospecific epithet with a nothogeneric name.

Ex. 1. Heucherella tiarelloides (Lemoine & . Lemoine) H. R. Wehrh. is considered to have originated from the cross between a garden hybrid of Heuchera L. and Tiarella cordifolia L. (see Stearn in Bot. Mag. 165: ad t. 31. 1948). Its original name, Heuchera tiarelloides Lemoine & . Lemoine (1912), is therefore incorrect.
Ex. 2. When Orchis fuchsii Druce was renamed Dactylorhiza fuchsii (Druce) So the name for its hybrid with Coeloglossum viride (L.) Hartm., Orchicoeloglossum mixtum Asch. & Graebn. (1907), became the basis of the necessary new combination Dactyloglossum mixtum (Asch. & Graebn.) Rauschert (1969).

H.11.2. The final epithet in the name of an infraspecific nothotaxon of which the postulated or known parental taxa are assigned to different species, may be placed subordinate to the name of a nothospecies (but see Rec. H.10B).

Ex. 3. Mentha piperita L. nothosubsp. piperita (= M. aquatica L. M. spicata L. subsp. spicata); Mentha piperita nothosubsp. pyramidalis (Ten.) Harley (in Kew Bull. 37: 604. 1983) (= M. aquatica L. M. spicata subsp. tomentosa (Briq.) Harley).
