Mini with a pseudobulb and yellow flowers

[harpspiel]

Just got this in a grab bag, the grower doesn't know what it is but says it has a long, wiry flower stalk with pale yellow flowers, and that when happy it grows into a tangle of bulbs. Based on where it's cut, it looks like it spaces bulbs out quite far in a chain:

It looks like something in the Oncidium alliance.

I was thinking that, looks like Oncidium globuliferum, but that only has 1 leaf per pseudobulb.

Maybe Encyclia or Tolumnia?

[harpspiel]

Tolumnias don't appear to have pseudobulbs, and Encyclias appear to generally have rounded rather than flattened pseudobulbs. I'm not seeing a small Encyclia with pseudobulbs or growth habit like that, so I don't think it's either of those.

I guess I'll have to post pics of it in bloom...

The form and habit look a lot like my Rodriguezia decora - individual growths with long roots on long rhizomes, easily separated. I don't think it is that particular one, leaves are much more narrow on your plant. But something in the Oncidium tribe a good possibility.
