[quote=Nemo the Clownfish;1114730]I have a couple of things that I have to wait and see to find out what's going on. I have a Melon Sword that now has two thin leaves going up, at the edge of the middle part where the leaves originate. I have to take a picture of them. As I see it, they could either be a new baby plant or some kind of hitchhiker plant (I've had this plant about a week and a half). I have had other leaves come up from the Melon Sword that looked to be typically shaped as the other leaves, but these are lanceolate? (long and thin). They look so different that I think it must be another type of plant and not a rootlet-based plant.[quote]
I'm wondering if what you see is an inflorescence? New leaves will always emerge from the centre of the crown on all Echinodorus plants, and some of the older outer leaves may yellow and die periodically. The inflorescence is like a stem, with nodes from which adventitious plants will appear, or flowers wold if grown emersed.
