Nope.. veination is too different..so is leaf shape. Think it is an echinodorus of sorts. a small parviflorus perhaps?

Emersed Helianthium quadricostatus (used to be a Echinodorus)? Grow it a bit and see. If it sends runners, more or less confirm.

Staurogyne is a stem plant isn't it?

thanks guys.. will grow it first.. its melting now though...

I think its still written as Echinodorus quadricostatus on most websites like Tropica.

[CK Yeo]

Forums are usually faster keeping with changes in naming. The genus applies to all the chain swords e.g. H. tenellum (E. tenellus). I am sure Tropica know it but probably for commercial reasons, they are not able to change well-established plant names immediately; people won't be able to find them on their catalog while others will think it is a new plant.

Though I am not sure if they actually accepted quadricostatus as a species (I think only Rataj did, but then again, he accepted everything as species).

i google Helianthium quadricostatus but found nothing.. i googled

Echinodorus quadricostatus and all the infos and pictures are there.. i guess most people still take that plants as E.quadricostatus though..

anyway, any idea where i can find Staurogyne sp in sg?(not tropical though.. too ex)

[doppelbanddwarf]

Oh I see, thanks for the clarification.

[CK Yeo]

Yes. I can't remember if they did anything with E. quadricostatus. I think it was something about it being a triploid/tetraploid or something like that. For all you know they might decide to lump it with something else based on genetic evidence. But nevertheless chain swords should be under Helianthium (for now at least).
