Re: H. difformis

I posted this question before, but didn't get any response, soooo, I'll try
again.  I'm puzzled by the growth habit of my h. difformis.  It grows up from
the substrate about 2 inches, then parallel to the gravel for an inch or so,
then up to the surface again.  This makes for some very interesting S-shaped
stems, though it is not quite what I was hoping for.  Any explanations?
