When I had my A. ulvaceous plant growing at its healthiest, its leaves had
long stems (petioles).  It was in a 75 gallon with four 40 watt T-12s with
CO2 additions.  I thought the plant looked its best.  Later, I tried
planting it in a very high iron oxide soil, as an experiment, and it went
downhill, growing much shorter, compact leaves, and finally dying.  I've
got pictures of it, which I will be bringing to the AGA Conference.
