CS, you may be right, in fact I know you are right! Look at Svennovich's picture, definetly not round leaves. But, when they are young, small plants, I bet they are more round shaped like the true dwarf. Thats what I was trying to say.
I am sure that the small form from Oriental is a cultivar. All Lobelia is red/purple when grown emersed or terrestrial. Underwater it turns solid green
I had some small form Lobelia once last year from Oriental aquarium. Before that I was also selling Florida Aquatic Nurseries "Dwarf Lobelia". FAN identifies it as dwarf lobelia, but it is not the "small form" which is unique to Oriental Aquarium.
I think it was Jay Luto that made me give him his money back on the Dwarf Lobelia because it wasn't the "true small form". Since then I decided not to carry it and only occasioaly get the true small form thru my importer. So Tony, I do not know what you got, I do not remember. If it was in a pot then it was from Florida. If it was in a bunch then it was the real thing...the same plant that Charlie gets occasionaly. In fact Tony, I am pretty sure we have already had this conversation! Your picture looks like it's the same as Svennovich's.
I am also sure you folks are experienced enough with plants to know that they do not always grow uniformaly the same shape! Species often vary in shape and appearance. The main thing is as far as I am concerned that the "small form" from the Orient is the smallest varient of Lobelia available period. And that seems to be what everybody wants who likes this plant. This is the plant you can use as a foreground/middle ground, and the "dutch streets" without worrying about it outgrowing the space. Does Charly currently have any? I do not pay a lot of attention to his emails, so I don't know. Other than him or me, nobody else is selling it online to my knowledge.
