Hey Bonnie,
Despite the title some unknown person added under my name on KP.....I'm not really the lily police.<g> But I am curious, I don't have the Speichert book, does he offer any information on the hybridizer or the date of origin?
But to answer your question....if you got the lily labeled as 'Improved Firecrest' from someone you deem trustworthy, there is no reason to now call it an unknown. If the person you got it from can provide provenance, that would be great. But there does appear to be a lily by that name, although a quick search turned up no listings of anyway selling it.
More or less that is right Lawanna, not being in bold doesn't mean such a lily doesn't exist, just for one reason or another the name is in question or not yet accepted. The whole registration/publication thing does nothing but protect the name from being used later on another lily.
