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.
