Just wanted to tell a quick reassuring story for anyone whose scorpioides gemmae don't pop up right off the bat. In one of my pots with really old plants in it I plucked the gemmae last year and spread them all over the pot. They never came up, not a single one. I have so many plants I never really payed too much attention to the fact that there were no new ones. A week or two ago, I was looking in that pot and they are coming up finally, after sitting for almost a year. It's conceivable that these new plants are from seed but doubtful. So all I'm saying is "Leave it alone, just let them come!"
