Well, at least the catatantes gives you something to work on. I totally know that it is never "a sure thing" when Id'ing a NOID. Trying to get "close" so that it can be cared for appropriately is nice too.
Great looking oncidium!!!! Noid oncidiums are almost impossible to positively ID. Just too many variables and variations. Where I live in China it is even more difficult because of the language translation problems.
