I don't recall any Cym that looks anything like a Catasetum or vice versa... However, Cymbidium and Catasetum (and Grammatophyllum and Ansellia and Eulophia) are related.
Thanks Roberta!
I finally remembered ------ this link here -- Click Here, is of Cym. Picanniny 'Dark Knight' and it sort of reminded me of some Fdk. flowers.
You're right though. Not pure catasetum. I should have just wrote Fdk. or something.
