Plant ID Help (very thick stemmed plant with thick watermelon colored leaves)
 
I know, I'm probably overloaded with stem plants but what the heck :-) I'm unfortunately thinking this one will eventually require higher light and/or CO2 (due to the very thick stem and roots as well as the thick watermelon colored leaves). It's been stationary for a week and has shown some growth though.

I think this plant might be Gymnocoronis spilanthoides, a marsh plant from areas in South America. The white blotches on the leaves lead me to think you might have the white-green variety that Kasselmann mentions (without photos unfortunately) in her book. She writes that this variant grows well emersed (i.e., in air with roots in water as in a marsh or bog) but has limited adaptive capabilities to submersed cultivation and is a moderate grower. Good lighting is important for the normal green variety, and I would assume for this variant too, in order to prevent the internodes from stretching too far apart and rotting of the lower leaves. I've never had this plant myself.

I just looked through "trusty" google and most all of the photos I found for Gymnocoronis spilanthoides are not a match. They all had thinner green stems and pointed leaves. This has a maroonish color stem. It may very well be a marsh/semi-aquatic plant as out of the water it is fairly rigid and can stand upright. It sinks when you put it in the water. The leaf shape throws me off though as it does not resemble any of the photo's/references I found. I also found mixed descriptions of it ranging from fast growth low light, to needs CO2 and high light. Google results were all over the board. I wish the LFS wasn't over an hour from me or I'd "swing by" and see what they have it labeled as.

One has to be careful when searching photos through Google or any search engine. I recall Heiko Bleher warning me never to trust anything I found, as most often it would be mis-labeled. How true. I have done searches of specific fish species and come up with a multitude of different species like you wouldn't believe.

Kasselmann's description of the stem is that it is green or wine red. And the photo in Kasselmann, and that in Hiscock, of the true green form certain looks like your plant in leaf shape and arrangement.

If you call the store, they should be able to tell you the name on the plant. It may or may not be correct of course.:roll:

I believe you over the store any day of the week :) Thanks for helping with this and the other plant ID's!
