I agree completely, which is why when i ask for photos I ask for the plants next to known standards such as colorata, regular macrandra, or regular rotundifolia. If you grow the plants next to each other in the same tank under the same conditions and they still grow differently from the "known standars" then it is safe to say that they are true variants rather than the same plant pretending to be a new variety (by being plastic through varying nutrients as you mentioned).
For instance I can grow regular colorata almost completely green even more green than the "H'RA" (aka gai lai) in the other thread or I can grow it as red, if not more red, as the "super red" in this thread.
For the record is it "gia lai", "gai lia" or "gai lai"???????
So ashappard..........of those 20 varieties, how many actually turned out to be different than regular macrandra. I have seen 5 true varieties........macrandra, magenta, macrandra green, macrandra green narrow, and butterfly.
i can't remember the story exactly (I will have to ask inspire about it) but I am pretty sure macrandra narrow green was found as an off shoot on either regular macrandra green or macrandra mini and if I am not mistaken butterfly either came off of narrow green or was mistakenly given along with narrow green. Don't quote me on this one, I will have to get the story straight first but I kind of remember either macrandra green throwing macrandra green narrow in my tank or the macrandra green narrow reverting back to macrandra green. It has been so long I can't remember. I will get the story and post it properly one day!
What I am trying to say is that there is a good possibility that they are all just mutant growth forms of the same species. Time will tell
