Default Echinodorus ID

I grow a lot of echinodorus species emmeresed and have most of them labeled.
I bought this plant as Echinodorus Osiris but I have a feeling its something else.
The new leaves have red splotches which dissapear with age. The stems are long about 20-40cm to the leaf. any help would be great
first pic is close up of new leaf


second is of mother pant


and here are some of the young plants

Yep, not E. x osiris - even though it can sometimes have spots.
Quite a few Echinodorus have spots.
If it had round (terete) leaf petioles, I'd immidiately say E. grandiflorus. But since that is not the case (if I see right from the pics), I might go for E. 'Rosé' - a child of grandiflorus by crossing.
Do you have a pic of a flower stalk? I have a feeling that this is not even 'Rosé' but a cordifolius hybrid (with triangular cross-section of petioles)...

That looks to me like a plant labeled as "Echinodorus cordifolius" in the botanical garden Berlin, also cultivated in the botanical garden Göttingen (Germany) as "E. cordifolius ssp. fluitans".
Probably the same cultivated plant, with large blotches on young leaves, is depicted as Echinodorus fluitans in Rataj's Echinodorus revision from 2004.
Compared with what I believe is typical E. cordifolius, the petiole tissue of the B.G. Berlin "cordifolius" is softer (and much softer than E. grandiflorus). Petioles triangular in cross section (as Daniel mentions), somewhat ridged. Also the peduncle is triangular (petioles and peduncles terete in typical E. cordifolius and E. grandiflorus). I didn't find pellucid markings in the leaves. Inflorescences branched, decumbent and always with plantlets, as in E. cordifolius. I didn't find ripe fruits. It appears to me like something between E. cordifolius and E. paniculatus.

And to confuse the matters, E. cordifolius ssp. fluitans sold by Tropica is a hybrid, too. According to our study, it is a cross between E. longiscapus & E. grandiflorus.

It's interesting that Lehtonen & I didn't find any paniculatus hybrids in our recent DNA study (which doesn't mean that there aren't any around).

One of several surprising findings in Samuli & Your study! But probably I don't know the plant Tropica actually sells as "E. cordifolius ssp. fluitans" (only the watercolor pic from Tropica). Is it a plant looking more like somewhat from grandiflorus group, than cordifolius? Suitable for tanks? Do You have a photo?

Was a plant looking like that from AQUANZ included?

Well, the plant looks more like a cordifolius... though with some characters that throw one really off the course! Submersed leaves are rather narrow elliptic... more like the pics of the young palaefolius or something. The plant stayed like that for a year or two and then decided to grow out of my 63 l tank.

I might have some pics on the other computer... can't do them now for 2 weeks as I'm off for a trip.

I don't think that we had any plants that look exactly like the one of AQUANZ.

WOW cheers for all the helpful responses.
Im currently converting one plant to submersed growth will post some pics when it gets new leaves.
thanks again

Thank You for the infos! I'd say, the curious Tropica-"fluitans" is one of the cases where a cultivar name would be the best solution.

@AQUANZ: OK, let's see; I had the "Berlin-cordifolius" a short time submerged, it developed rather narrow leaves and long petioles, I removed it before it grew emersed leaves. In a large tank in the botanical garden Berlin I've seen it growing out of the water, with very long petioles.
