Yes, I went back and read *your* excellent article in PAM Spring 2000.
(Isn't he modest, folks?) ;-) Mine look like the crowded ones at the
top of pg 27, in the 70-gallon tank. The longest ones are at least 6mm
wide at their widest point, in the middle. The more well-behaved plants
are 4 mm wide or sometimes smaller. Working from the chart on PAM Sprin
2000 page 33 I have both c-1 and c-2. According to your article, I
should have the longer leaves in the corners where there is less light.
But the longer leaved plans are in the middle, where there is the most
light, but more crowding. Perhaps crowding is a stronger variable than

Yes, thanks for that comment, Robert, because not everyone knows this.
These particular plants, however, have been fully submersed and growing
strong for three years in the same aquarium. The leaves are definately
demonstrating submersed growth.

Mine are like Johnson grass and not like bermuda grass.

Nope. That's not it. No spoons.
I have to go back to work now before Erik finds out I've been goofing
off instead of working on the new TAG.
