Could be a flower or a new leaf I have had several kinds of crypts but never had 1 flower that I recall. But grown emersed, flowers are how the cognoscenti can often ID them (not me, lol)
What kind is it? Twisty midrib & bullations (puckery spots on leaves), not 1 I recognize here. So many crypts!
I'm sure it's happy, maybe you'll be able to tell in a couple weeks
