The only addition I can think of is Ammania and Nessaea (sp?) which
may be hard to find.  By the way, Crinum thaianum is Asian, Crinun
Natans is African.  C. thaianun has straight leaves, C. natans is

If you are "flexible", you could add the plants that are not just
limited to Africa - Watersprite, Hornwort and Hairgrass for instance.
If you want to include Madagascar (although it is ecologically
isolated) you can choose from a whole bunch of Aponogetons.

I've had this plant likely longer than anyone in the USA besides Dan Q. It
likes light and is a slow grower at first. It may take some time before it
gets going(perhaps 2-6 months maybe less). Mine are nice and big( I think I
have about 10 or so). Your gravel should be fine. The bulb is sensitive and
some folks have suggested wrapping it in peat, then planting the bulb. I
didn't fine this to work very well and it caused more problems for me. I
also have 2 plants that are aquatica but I'm not sure if they are different
types or varieties. Same applies to them. I just make sure I'm very careful
not to bruise the bulb when I plant them and also DO NOT move them unless
you have to. They hate this. Over the years I have gotten 2 brood bulbs. I
would suspect that it will take quite some time for anyone to propagate this
plant and most will never do it unless they keep it for many years
undisturbed. One of my top 5 fav plants. It not picky as far as temp
goes.......72 to 85F.
