football shaped? What about size? Washingtonia seeds are spherical and super dinky (about the size and shape of a large peppercorn). CIDP seeds are frequently infertile since you need a male and female in very close proximity to get good seed (not always, bees can move pollen a good distance, but then you really dont know what you have until it grows pretty large- very common to get hybrid palms from ripe CIDP seeds). Can't comment on Royal seeds since I have not seen one up close.

Unless I mislabeled them, one of the CIDP seeds has sprouted. Long wait ahead...
