What alliance is this from?

[let_it_grow]

So I've heard that this orchid has been renamed a few times and I don't know what to call it or what alliance it's from but it's making it hard to find care instructions for it. It is labeled as Sigmatostalix radicans but I have found 3 names for it:

Sigmatostalix radicans
Ornithophora radicans
Gomesa radicans

So my questions are; Is that the same plant?
What alliance is it from?
And most importantly how do I grow it?

It's currently growing like a weed with 12 new pseudobulbs growing off what used to be a fairly small plant. Each of the old pseudobulb has sent out 2-3 new pseudobulbs so it's over doubling in size from when I got it at the end of November. It's getting 12 hours of light at about 3000 fc (not exactly sure cause I'm using a light meter app on my phone but that is the average reading I'm getting for it). I'm growing it in a small terrarium with lots of humidity and although its potted in moss most of the new roots are just growing in air and have not grown long enough to touch the medium yet. So how should I care for this little gem and how can I make her bloom when her new growths begin to mature? Any info would be appreciated

I think that's Oncidium alliance - Gomesa is anyway..
Hopefully someone can confirm (or correct me!)

Ornithophora radicans is the accepted name for hybrid registration, with 2 registered hybrids.

Ornithocidium Marie (Oncidum ornithorhynchum x Ornithophora radicans)

Ornithocidium Roczonii (Oncidium riograndensis x Ornithophora radicans)

So yes, it is Oncidium Alliance.

And yes, it grows like a weed. I don't think you can go wrong with it. You're growing it brighter than I ever did, but if it looks healthy I wouldn't change anything. If you're fertilizing regularly use a low nitrogen fertilizer. Give it few more months (or more likely weeks) and I bet you'll have flowers, and pretty much continuously from then on.

Thanks so much. I was wanting to move it to my larger terrarium because its taking up so much room but it has a lower light level. Think I can get away with 1500 fc?

It did well for me in a bright north window with no direct sun. I think 1500fc is probably fine.
