Paul, what an interesting factoid! I didn't know there was speculation that it was another cultivar.
If I may say so, from the limited resources I have, I don't believe it is the same flower. Judging from pictures only, 'Mormon' doesn't appear to have the same substance as Mynelle's Starfish (it almost looks crepe-y, even) and, while it has the same sort of shape, Mynelle's Starfish has a very consistent appearance on the edges across all of my blooms--more pinching and definitive shape--that the picture of Mormon doesn't have.
