Id Sumatran echinodorus

[medicineman]

I've got this plant for around one month now and it grows much taller than when I harvested it from a Sumatran river in Lampung province. The growth gets much faster since I use a huge DIY external reactor so I can crank my CO2 beyond normal rate. The leaves are kinda soft and thin unlike most echis and the overall shape from the root to the leaves strongly resembles echinodorus sp. There is something like flower stalk coming right up real quick to the surface and in two days maybe I can take a shot of a flower.

that doesn't look like an Echinodorus, which is native to South America anyway. Of course Echi has spread all over the place but the wait till the flower blooms then you can tell.

Looks like some species of Ottelia, possibly O. alismoides (google around for photos)... the word "alismoides' itself means "similar to the family Alismataceae" (Alismataceae is the family in which Echinodorus belongs)

I dont really know... because the plant reminds me right away to echinodorus sp... .. With the leaves' nervatio and the plant structure. The height and very thin leaves are however not disticnt to echies, that goes for the limpy stalks as well.

There are two wannabe flower stalks (I guess so because they look different from leaf shoot), one of it is already nearing water surface.

O. alismoides.... that is interesting. I'll check it out.

edit : I've checked it out and that ottelia plant resembles this specimen I have. Flower will be a sure way to ID this one.

Cannot see the vein structure very well from the pic. Could you try a closer shot of the leaf? The height of sword plants tends to be very plastic and depends on the growth condition.

I suspect it is an Ottelia as well. The only other Echinodorus I could think of with limpy leaf is E. berteroi (cellaphane sword) which looks a bit different.

I think I had this plant before. The stem is quite hollow and easily snap , more like the local spinach. It flowers frequently and the flower is white, once the flower touch the water, it melts. After flower melted, the seeds are disperse and flower holder open up like 3 robot claws.

This is a nice , easy plant. Taiwanese call them "Che Qian Zi"

Crap.... no flower pic for those of you who like to see any. My fish decided that they like the flower part, they ate it just when the stalk almost reaches the surface. Two of the stalks ... left with no petals, and it does not continue further to the top. To annoy me more, they also ate the tip of my anubias flower .... you know the plant only flower once or twice a year.

culprit : seems to be my juvenille congo tetra

There you go, today I take some closer pics of the plant.





Now there are three flower stalks, but two are already somewhat damaged. No idea if they can ever unfold to the surface. The other one is still in early stages, hopefully will not be eaten again

I think that by the flower stalk you can already tell it's not an echinodorus, which have flower stalks where baby plantlets and multiple flowerheads develop at regular intervals.

[medicineman]

Yeah I figured it out so. When I got the plant was small and echinodorus like, so naturally I guess it as one

After looking at your latest picture, I confirmed it is what I mentioned previously.

The seeds will be sleeping for some time some where in the tank. After I removed the mother for few months, for some odd reason after long time, the seeds will start to sprout and come out. I even managed to grow it on the DW.
