Those flowers look a little different from my macrandra flowers...
1 x 150W metal halide, 8 hr photoperiod.

They look different by color or structure?
The pics above look similar to the photos of R.macrandra 'green' inflorescence that I've seen elsewhere.

so if you were to cross you would just pollenate (sp?) from a different rotala and wait for seeds?

Looks like a different structure. Though I didn't take a picture of my first R. mac bloom. I've been waiting a few months now for the second bloom to happen.... hasn't happened yet... stupid plant.

not sure, but I think it would be as easy as rubbing inflorescence from a couple different Rotalas together and wait for seeds. Maybe an oversimplification, and I could be way off. I have read that Rotalas hybridize easily but dont know between which spp or how easy it really is. I hope to find out eventually, because I'm dedicating a setup to rotalas and I'll try to cross.

I find that bright light is good for development of the flowers. Once I put my rotalas under metal halide, they became covered with them. Another plus with rotalas in an emersed setup is that they do not take up much space above the waterline; they dont grow into trees like Hyptis or some of the Hygros for example.

I haven't seen too many up-close pics of Rotala flowers and thats a pity. I have seen pics of R.macrandra 'japan' and the color was more pinkish but otherwise had the same structure as the R.mac 'green'. Please do post some pics if you get flowers again.

Yep, will do... this plant is taking its sweet time... my other R. mac flowered when it was only a small stem (3 inches high), my other R. mac is about 7 inches or so, and branched off multiple times to create a kind of hedge and still no flowers... Perhaps I'll try a strict 8 hour light regimen and see if that triggers it.

I picked up "Rotala sp "Butterfly"" and Rotala macranda "Japan" at Aqua Forest a few months ago. I have been growing them side by side in the same tank. Here are a few pics for comparison.

The names I list are the names given to them at Aqua Forest.

Picture 1: off-040210-10.JPG = Rotala macranda "Japan"
Picture 2: R_macranda_japanese-030810.JPG = Rotala macranda "Japan"
Picture 3: Rotala_Butterfly-01.jpg= Rotala macranda "Japan" on left and Rotala sp "Butterfly" on right
Picture 4: Rotala_Butterfly-02.jpg= Rotala sp "Butterfly"
Picture 5: Rotala_Butterfly-03.jpg= Rotala sp "Butterfly"

Other than down-sizing, the pics are unmodified from my cell phone.
