As I wrote earlier for BULBS: My Hippeastrelia is a cross between the
hexaploid form of Sprekelia and a tetraploid hippeastrum cultivar. A
"cross' with hippeastrum again only did give me the hippeastrelia again,
a case of apomixis. However a cross with the hexaploid sprekelia did
give me genuine intermediates. All was checked by measuring nuclear DNA
content So if you send me  a seedling of your batch I can check it for
you and you don't have to wait for flowers.
