Looking for a profile of rotala indica. Been searching but all I can find is rotala rotundifolia. Plantgeek has it listed as incorrect. Is there a difference?

There is some discussion about whether there is a difference between the plants named R. indica and R. rotundifolia.

From my reading, it seems that there are two different species but that the one circulating in the hobby in the USA is R. rotundifolia.

Here is Tropica's information on R. rotundifolia / indica.

Here is some information from the USGS web site which states:

Rotala rotundifolia produces flowers on terminal spikes (racemes) and differs from a previously introduced species, Rotala indica, which is an annual species with shorter, lateral flower spikes.

Another link to information about Rotala species.

Well they didn't ship well but here's a pic.

Simpte 27,
What you have is most likely rotundifolia, even if it was labeled indica. Indica is a blood red version that is hard to find in the US.

This is a good example of the difference,

So what it this? Not the best pic, but it should show the shape/color.

I have doubts that the difference between Rotala indica and Rotala rotundifolia is blood red coloration. I have the 'colorata' version of Rotala rotundifolia, and it is /much/ more similar to Rotala rotundifolia "Green" in vegatative morphology than the thick-leaved, more robust looking Rotala rotundifolia most commonly found in the USA.

Someone needs to special order some Rotala indica along with a bunch of Rotala rotundifolia from Oriental Aquariums, grow them together, photograph them, and take their pictures. Maybe this is a good summer project for me.

Would be nice to know the diff. I see too many people selling the wrong plant. I thought I was getting indica but it seems otherwise. Not a big deal as its still a beautiful plant and I'm not quite ready to take on some of the more delicate plants yets. I'll stick with what I can grow.

Why don't our 2 pics look the same. Mine has lost a lot of the reds but is still growing well. My ludwigia ovalis has lost some of its red too but my rotala doesn't look like JanS pic. Is it a hybrid?

I've heard that it's basically impossible to tell the difference without seeing them flower.
