Yes, this cross (in the current nomenclature) is C. warneri x C. labiata; but keep in mind that in the '70 the Catt known today as "C. warneri" was named "C. labiata v. warneri", and the current "C. labiata" was "C. labiata v. autumnalis". In the head of an oldie guy like me it's everything "labiata" (which in fact they probably are...)
