Plant ID help

It might be Hygrophila angustifolia

Chainsword looks like to me. Lego's name may be that tho, im just not good with scientific names.

It's Hygrophila corymbosa 'angustifolia', most likely. H. angustifolia (just straight angustifolia) is actually a different species:

Not the same. http://www.aquaticplantcentral.com/...s.php?id=139&category=family&spec=Acanthaceae

Interesting Tinanti. I thought they were the same species. So the true H. angustifolia is pretty rare in the hobby then?

It is here at least. It does show at least superficial similarities to the 'Sarawak', but I'm not certain of that yet. I should be able to find out, either by flowering it again and comparing to some good descriptions and/or with help from some specialists I know. It's on my list though.

don't mean to thread jack but...is the only visual difference between the 2 the flowers?

I don't know offhand what all the differences are, but when we compare them side by side (or at least their descriptions), differences like pubescence on the stems, bracts, flowers and so on will be apparent. They also occupy different ranges, etc. Yours is a simple question with a complicated answer!

More later.

Thanks for the help guys.
