Hello again Ms. Lilith,
I would have to say that the plant pictured most resembles Anubias barteri.
The thing with Anubias is that none are radically different enough to be construed as off beat, imo. A. heterophylla and A. gigantea have hastate leaves, but due to all kinds of difficulties, I don't know of anyone importing much from West Africa any longer, so what you come across are mostly TC plants. Coffeefolia has probably the nicest leaves, but doesn't get particularly large. A. 'Frazeri' makes a nice large specimen plant.
Other thing is....realy none of the Anubius want to be submerged. They are amphibious terrestrial plants that can survive seasonal submersion, but growth is most rapid in the emerged state. But obligate aquatics they are not.
The only ones I have on hand at the moment are A. 'Frazeri' and A. barteri var nana.
