Limnophila aromatica or hippuroides

[geoffrey]

The Gratiola sp. that we so often use and see, are they also known as Limnophila aromatica or hippuroides? From Oriental's catalogue, aromatica has opposite leaves per node (emersed) and that does not seem to be the same from those I gotten from Teo which have 3 leaves per node (emersed also). What are mine?

From pics on the net, sumbersed Limnophila aromatica sure looks like the submersed Gratiola sp I know.
The emersed version of Gratiola from Teo's has 3 leaves per node. One thing is that when you break the Gratiola stem, it has a herbal smell.
In Kasselmann book (p.339), the emersed Limnophila aromatica has 2 leaves per node.

Its neither of them Bros....another species originating from Vietnam.

it is not limnophila aromatica for sure. limnophila aromatica, if you cut it, there is a herbal smell (used as a herb in Vietnam). I have emersed limnophila aromatica and it has red stems not like those i see on the internet. I have seen it grow in Vietnam paddy fields and it really have very reddish stems.

also when grown submerged, limnophila aromatica retains its 2 leave per node state but the red stems becames green. Submerged specimens do not look like gratiola at all.

but if you check the tropica website, they say there are variants to this plant and their is from Malaysia.

cheers

quite confused here....so will Gratiola have a herbal smell if its stem were to be broken?

Now, who is the real Gratiola? It's impossible to tell them apart when they are submerged. Could someone show a pic of an emersed hippuroides?
