Len:

I have this plant and it is very interesting.  Mr. Holger Windlov of
Tropica in Denmark introduced this in Germany at Interzoo a year ago and
gave me a piece.  He found it in Thailand and just calls it a true
floating Ludwigia.  Strangely enough, when grown out of doors (in a 
pond), it takes on an entirely different appearance -- all green and
blooms continuously with small buttercup-like white flowers and the white
flotation bladders.  When I bring some in for the Winter, it reverts to
your description above -- and grows well under Triton lights.  It does 
not grow submerged!
