	Thanks to both of you.  I'm now just about certain I have 
A. sessilis.  It's doing nothing except put out roots from most of
its nodes.  I grew one A. species years ago, but it died out.  The
differences you indicate are consistent with my memory of the one
that grew and my observations of this one.  I got it from Big Al's
in that horrible shopping centre in Kanata.  I think I'll put it in
a pot.

	It's about time I joined anyway!  I'll contact you directly, David.
