Lagenandra thwaitesii I Think

  Here is my first specimen of Lagenandra.  I got it without being certain of the name.  It’s not all that common and when a plant that’s not common or easy to get comes along you have to take a chance sometimes.  I think it is L. thwaitesii but Im no botanist.  I have it growing in a tub potted with 1 part coarse sand and 2 parts potting mix.  It is soaking in one to two inches of water at the bottom of the pot.
