R. indica and R. rotundifolia are the same plant.

Are you sure Phil? I know that on Tropica page r.rotundifolia=r.indica but i'm not sure that true. I think that rotundifolia grown much fast than r.indica, had thiner leafs and is red-orange (r.indica is pink-red)
This IMO is r.rotundifolia (2 long leafs, red/orange color, very similar to r.spec. green):

and this is r.indica(3leafs):

I think that all pictures in PlantFinder in r.rotundifolia are wrong because it's not this plant(there is r.indica on pictures).

I think that is Rotala sp. 'Rio', I remember Alex from Brazil showing me a picture of it, it had two leafs per node.

I don't think so because i buy my 2leafs rotala in shop and this was pot from Tropica Denmark(it was r.rotundifolia, i think Tropica haven't R.sp "Rio" in his offert). Compare r.rotundifolia and r.rotundifolia green...it's the same species: thin leafs, two per node, fast grown....only color is different :wink:. If r.indica=r.rotundifolia why she don't looks like r.rotundifolia green and she has 3leafs per node?
