Goldenzelle does have long leaves but not as proportionally long as tenebrosa.

Your hybrid is also on the Palmer Web site:
Rth. Elizabeth Palmer x Goldenzelle — Palmer Orchids

I wouldn't think an experienced orchidist would confuse the two plants based on plant morphology. But maybe Palmer received a mislabeled flask.

Yes, I visited Palmer's website and there I saw a photo of this orchid with the name of C. tenebrosa, it says that it was native to Brazil.
