We saw Aponogeton in South Africa. It is interesting
to read that you got
it to grow in a freshwater aquarium. I was
fascinated by it. It is
apparently both edible and aquatic. If you have
pictures of it and want to
add them, I'd have no objection.
As you know, this wiki administrator is more
inclusive than exclusive. If
someone can make a case for our including a plant in
the wiki because it is
a bulb, corm, rhizome, tuber, has tuberous roots
when it is growing, etc.,
we'd allow it.
We already have a few plants pictured on the wiki
that are sometimes
aquatic when in growth.
