. . . or maybe it's Epi. Sun Valley 'Pink Petticoats.' I couldn't find a "Petticoat Pink" in the International Orchid Registry. I did find a Sun Valley 'Pink Petticoats' on the internet, but the color isn't a close enough match for me to be confident about the ID. So I don't know what this is for sure.
And I mostly don't care, either. Not only am I not that into this kind of Epidendrum (though I like the ones with the orange/green/magenta combination, like Epi. pseudoepidendrum, the hybrids tend to be shaped more like this one, e.g. Rose Valley 'Caribbean Dream' or Neon Valley. I appreciate the distinct shape and arrangement of the hybrids, I guess, but they're just not my thing.
