So I'm not real sure this is a new rotala here, but I haven't seen any photos of it yet or any discussion of it for that matter........

I have been told by the person from whom I got it (Inspire 91) that it is called Rotala sp. 'ceylon' but I am not a stickler for phylogeny. It is similar to sp. 'green' except it can develop a little pink coloration on the underside of the leaves. The stem is thinner than sp. 'green' and it grows more "wiry". A few major differences that I have seen in this plant so far is that it can grow more that 2 leaves per whorl (usually 3) (as oppoed to opposite leaf pattern) and the leaves are really thin and fragile.

So far it seems really easy to grow also , a real keeper in my book

Any comments or questions please post.

This plant is most likely a regional variation of Rotala rotundifolia. It was given to me as Rotala rotundifolia 'Ceylon'. There is a Rotala sp. 'Ceylon', but that appears to be something different.

I'm growing this plant (thanks Cavan), and I notice a few differences. One, the leaves are wider than Rotala sp. "Green". Two, tops do develop a slight reddish tinge. It doesn't have that creeping growth that makes Rotala "Green" so annoying at times.

All these different rotalas are giving me a headache. Really, unless they look significantly different, there doesn't seem to be much importance to me. "green" is one thing, but for "pink," "colorata," "ceylon," or "NORMAL ROTUNDIFOLIA," isn't a lot of its appearance up to water conditions??

The differences are noticeable enough that they could be utilized in different ways. 'Colorata' especially is striking when nitrates are low. It's a deep red color, not pink like some of the others.

Rotala sp. 'Ceylon' has about the same coloration as Rotala macrandra 'green', which is one of the best aquascaping plants out there in my opinion.

Besides appearance, the growth pattern of 'ceylon' is way different than any other rotala I have ever kept. It doesn't like to creep like 'green' although it can and will. It also doesn't grow straight up like colorata or rotundifolia. The stems like to grow in a corkscrew almost. The only other rotala that can exhibit this type of growth that I have seen is 'Nanjanshan' but not to the extent that 'ceylon' does.

Maybe I will take a photo of rotundifolia, colorata, green and ceylon growing right next to each other.

Thanks for the clarification...I to have been calling mine Rotala sp. 'ceylon'...turns out it's Rotala rotundifolia 'ceylon'...not to be confused with Rotala rotundifolia, which for years I called Rotala indica, which turns out to be a different plant and was call Ammania bonsai, which I guess doesn't even exsist any more. Hope this post helps...LOL

I'm not so sure Rotala rotundifolia 'Ceylon' and Rotala sp. 'Ceylon' are two different plants. I think this might just be a case of different names for the same plant. Does anyone have a side by side comparison picture?

I suspect the differences we're seeing in pictures just have to do with tank conditions in which they're grown.

I don't know for sure, but I think they are indeed two different plants. Note the blunt leaf tips on the 'Ceylon' from the last link; I don't think something like that can be due to environmental conditions.

I'm not agreeing with anyone with this post, but I must say I have seen different leaf size with this plant. Never as skinny and long as in the link that Cavan posted, but currently the leaves on my ceylon are way bigger than what I have seen in the past.......they are almost as big as they are on Rotala rotundifolia 'broad'. In other words, they are almost twice the size as the photo I posted plus they are a way deeper colored green than normal, pretty much the same shade as sp. 'green' instead of the regular yellow-green or pale green.
