That plant I believe is Echinodorus parviflorus, the natural species. The inflorescence is significantly shorter on this species by comparison to others, rarely if ever reaching the surface when the plant is grown submersed. And I assume this is what you are referring to, Boredomb.
The usual common swords, like Echinodorus bleherae, grow the inflorescence to the surface before adventitious plants really appear at the nodes. And they would look like this, which is what Inga I suspect was referring to.
E. parviflorus remains shorter and the well-developed adventitious plants suggest that is what this is. Also the leaves, the wider are the emersed, the narrower the submersed, of the natural species. There is a photo in our profiles of the natural species and the more usual "Tropica" variety for comparison. The inflorescence on the "Tropica" variety is the same, obviously a trait from the parent plant. I have inflorescences on some of my "Tropica" plants and they remain about 8 inches max and develop plantlets.
