Ron, that looks like A. boivinianus. Darker and more bullate than my pictures, but otherwise looks like it. If you have trouble growing it, that may be more evidence leading to A. boivinianus. Primarily a cool water plant, similar requirements to A. madagascariensis. Reminds me I got to get revive mine, it suffered from some tuber rot and now growing very slowly.
On the picture, is it just me or do the leaves look quite thick? See if you can ask where it was imported from.

Since this thread, I have cut at least 2 stalks. The second one i didn't spot until it was near the surface, but chopped it anyway.
Shame that I don't have any seperate plants to pollinate with.
Here's my A. ulvaceus now. Basicly just floating in my nano cube and occupying the whole the thing. Below it is a 11"x11" glass. It has not gotten petiolate, but I think it will when I move it to another tank.
There are only a few leaves on each of the other tubers (madagascariensis, capuroni, and longiplumulosus). A. capuroni is on the left and A. longiplumulosus is on the right with the less wavy leaves. And there is a lace leaf visible in the image as well.

Mark, that's one big bunch of ulvaceus! Did I read wrong that it was 'just floating', ie not rooted in substrate?
I'm curious which plants the capuroni and longiplumulosus are, so please don't mind me 'borrowing' your image for clarification. My knowledge of plant sucks and a picture does convey a thousand words.
I 'lost' my capuroni, but that's probably due to the change to submersed leaves and that I no longer recognise it from the day I bought mine.
Is this it?
I'm back & keeping 'em fingers wet,

Ron,
Indeed, the ulvaceus is just floating around. I did not want to root it down because it will make a huge mess when it outgrows the nano tank(which it has!). I am scared though. It is now such a huge mass that I have to add more fertilizer than usual to make sure that it is not draining the tuber of energy.
Switch the labels around and you got them right. A. capuronii seems to be strongly wavey when compared to the A. longiplumulosus. The plant you have pictured definitely looks like A. capuronii.
A. capuronii seems to be a variable plant. Kasselmann has it pictured in her book and it looks nothing like what I have. Instead the leaves look quite thick and are highly bullate. It's another variety I would not mind finding.
About Red lace in the last few posts. Honestly, I really do not know what it would look like. Looking at the holes and narrowness of the leaves, it looks like var. madagascariensis- unless they are not fully developed yet.
Don't let lack of plant knowledge stop you buying plants! The terminology and latin names for aquarium plants is esoteric but atleast we can agree to their beauty.[/i]

Wow, thats a pretty funny looking ulvaceus without petioles. Here's mine...petioles about same length as the leaves.
This is a 46 gallon bowfront...the right side is cut off a bit in this shot, so add an inch or so to that photo and you've got it.
BTw, how can you tell it is draining the tuber for nutrients? I have mine over a mix of sand and laterite, and dose flourish weekly(though not it a concretely scheduled manner). The thing continues to try to flower, should I be worried?
Poor fertilization will exhaust the tuber. Though not always noticeable, the tuber itself may shrink and there is possibility of part of it dieing. Amount of nutrients can make a difference on recovery after dormancy.
Strong lighting and low water levels have kept the petioles short. Do not be worried about the flowering if you are fertilizing. But usually, after the flowering is done, it will retract it's leave and go into dormancy.

Well, I felt around the tuber and if it has shrunk, i'm not sure. Stuck a few Azoo tabs around where I suspected the roots were going though.
Shrinking and death happen in extreme cases. I only had one tuber shrink and part of it die. It was an A. natans that was left in a jar with no light for an uncounted number of months. Has not fully died yet so I scavenged it to see if it is not stunted.
-Mark Mendoza
Well, I chopped yet another flower stalk today.
I'm not sure if what I'm doing is pointless as by the time I saw it it was already 2 feet long....so the plant must have poured a lot of energy in already.
Btw, I think that what may work would be when they go dormant to put it on the same substrate a it was in the aquarium only keeping it moist-perhaps start with water and then let it evaporate to emulate a dried up bottom?
