Cryptos With Long Stems?!

[notg2009]

Hi all,
2 of my cryptos have sent long stems up without them turning into leaves, but at the end they have few leaves coming off of these. Since there are 2 plants with the same issue, I was thinking maybe those are different types capable of doing that. Any comments?
Take a look at some pics:

Looks like a runner, my swords do this from time to time, reproducing.

I thought runners "run" horizontally and make roots every couple of inches, but this "stem" has gone upward. Now it has some leaves, and roots. Should I bend it and plant the new roots in the gravel?

A picture would be great.

Here are two recent photos I took about 5 min ago:

They're just runners imo, ive seen them before on pictures of people propagating plants

So can I cut right below the new roots and put in gravel as an independent plant? How can I induce this state to get more runners, and more plants?

I should think so yes, or you can just tuck it under the gravel still attached, doesnt matter really, the runner bit will eventually fall off of its own accord

And im not sure, i'd imagine good growing conditions would be all that you'd need

they arn't Crypts they are Echinodorus tenellus in their submersed form. That is a runner, you can either re-plant or just trim it off.

I checked the leaf patterns, color, leaf shape, height, etc. And they look exactly like cryptos. Is there any way to tell them apart? Do cryptos produce runners?

 

[StandbySetting]

Both produce runners, but I agree with Ian, it's E.tenellus, when Crypts send out runners the rounded part of the leaf begins to develop quite early on and before it gains any significant height.

No, Crypts don't produce runners, like that on the pics, they reproduce from the crown. It does look a little like Crypt Parva...it looks most definite like an Echinodorus species, maybe Echinodorus quadricostatus?

 

[StandbySetting]

Ian, Some of my Crypts have grown by sending out a runner from the crown, not sure if it's limited to some species as it's only a few species that have done it, the rest have reproduced from the splitting of the crown, but I'm certain that this isn't a Cryptocoryne species.

 

[ian]

It's just Crypts don't send out runners that long. That runner is double the size of the plant. I think we can agree its a sword species.

I understand the reasoning behind your comments guys, but how is it possible for 2 different plants to have the exact same leaf type??!!!!!

another question: I use Seachem Flourish for my plants, do I need to use root tabs as well? The substrate is gravel only.

Thanks for all your help.
