Amaryllis cross with Clivia

Most species of Amaryllis, Clivia, and Hippeastrum have a chromosome
number of 2n = 22, suggesting that a hybrid between any two of these
genera is theoretically possible. I suppose that is part of the
ongoing allure to attempt these intergeneric crosses. Of course,
there are many potential obstacles to creating such a hybrid and
success seems extremely unlikely without embryo rescue. There is
frequent mention of a Clivia x Hippeastrum hybrid created by the late
Gordon McNeil in South Africa called 'Green Girl' but there is no
evidence that I can find substantiating the claim that it is a true
intergeneric cross. The picture of 'Green Girl' looks like just
another nice Clivia selection:

'Green Girl' appears to be the only purported intergeneric hybrid
described on the Clivia Register list.
