+Echinocalycium P.V.Heath, ()
🌵 Author(s)

Graft-chimaeral genus for intergeneric graft-chimaeras of Echinopsis and Gymnocalycium.

The names of graft-chimaeral genera are formed "by combining part of the name of the genus of one of the component genera, connected by a vowel, with the full name of the other component genus (condensed formula), and prefixing the addition sign “+”" (article 24, International Code of Nomenclature for Cultivated Plants).

Based on +Echinocalycium japonicum P.V.Heath (Echinopsis eyriesii + Gymnocalycium mihanovichii var. friedrichii [= Gymnocalycium stenopleurum]).

This name is “not established” (invalid) under article 24 of the International Code of Nomenclature for Cultivated Plants as an incorrectly formed condensed formula (full name of the second component genus not included). The correct name is +Echinogymnocalycium.
