mr. held,

not being a botanist (me that is), i think however
that your instincts are right.  

as a matter of fact, some orchids lack leaves or stems
and have only roots, that are green.  obviously those
are the only parts they have to photosynthesize.  it's
quite a size to see these small orchids, that are
nothing more than a jumble of roots, flowering...
