Its 100% an echinodorus species, (sword) the flower is same as the ones mine have grown. The plantlets will start to grow roots of their own, I would leave them until they do though they would probably grow roots if you plant them in or out of the water.
I was sold an "Anubias" which turned out to be a sword then! I didn't know swords grow out of water as well (immersed). When I first planted it some 3 months ago, it had a rizone like that of an anubias and was completely submerged. I tied it to a rock and it it grew rapidly beyond the water level.
Could anybody tell me what type of sword it is? The water is too green to get a picture of what's it like below the surface. I'll see if I can take it out completely from the tank without causing too much of a mess, and get a picture.
I think its an EchinodorusArgentinensis (Aregentine Sword) or palaefolius. Both look almost the same. According to Wikipedia, it usually grows too big for most aquariums. Mine does 700mm in depth and I am tempted to put the whole plant in and see how it looks.

The rhizone is still there and no its not under gravel. Its tied to a fist-sized rock but the water is too green to get a view without removing it from the tank. I'll try that and post a pic.
