Lynn,
'Oddity' can sport back to 'Albidum' and those plants tend to produce more 'Albidum'. 'Oddity' is a chimera so that the epidermal cell lineages are mutant but not the core of the plant. That's why I was so excited with your very abnormal bloomstalk from a few years ago as it appeared to affect the deeper tissues and could give fully mutant seedlings. In the meristem of 'Oddity' plants the leaf primordia fuse at their backs, rather than staying as flattened structures. Very cool.
The date is wrong too. I had that plant in '72 as a gift from Sandy with the question ("What do you think?" Of course I wrote back "AMAZING!!!") and it's in Helen Payne's book that was published in '72. It's in Helen's 1973 catalog too. I don't have the copies of Sandy's list from that year.
