The photos of A. barteri var. nana in all these books like normal 
variation to mee.  If I saw these plants unlabeled, that's what 
I'd assume them to be.  In the Schuermann book, the picture I 
found (on page 65) is labeled as A. barteri, and that, too, is 
what it looks like to me.  UNDERNEATH the A. barteri are some 
smaller leaves growing on shorter petioles, and _this_ looks like 
it's probably nana.

They are the same plant.  For a while, it was thought that nana 
might be a separate species.  But under the most recent revision 
of the genus, it is part of the barteri complex.

It's not only lighting conditions that make the difference, nor is 
it only a matter of leaf size.  Even in nature, the plants are 
very variable. I have an A. heterophyla that I've had for at least 
6 years.  Last summer it threw a few leaves with basal lobes 
although all the leaves before and since then have been

No I don't, but based on past experience, I'd hope to see it by 
summer time.

Yes, it includes descriptions of all species and varieties I've 
run across in the trade and (hopefully) it will include photos of 
several species and varieties.

This sounds like a pretty good description of the flower structure 
of these plants to me!  The runners, like those of VAls, are 
formed beneath the substrate.
