The form I got from Diane lo, those many years ago, isn't just "dull, 
less well-marked". It's totally unmarked, with small leaves that I 
would describe as apple-green. Well, maybe not quite as bright a 
green as that implies, but definitely a light green.

I plead guilty to misusing the word "type" when I should have written 
"normal", "typical", "usual", "everyday", or perhaps "normative", 
forgetting in my haste that in the world of plants, "type" has a very 
specific meaning and it sure isn't a synonym for the typical form.

Is this discussion progressing toward a state of total enlightenment 
on the part of all those concerned with tiny aroids, or are we 
spinning our wheels over nomenclatural nits?
