Nothogenus for intergeneric hybrids between Astrophytum and Gymnocalycium.
The names of nothogenera for bigeneric hybrids are formed by combining the names of the parental genera "into a single word, using the first part or the whole of one, the last part or the whole of the other (but not the whole of both) and, optionally, a connecting vowel" (article H.6.2, International Code of Nomenclature).
According to Rowley (Brit. Cact. Succ. J. 18(1): 29. 2000) the three alleged hybrids in question show “no evidence of Gymnocalycium whatsoever”.
