I received a few orphans and cannot tell whether they are oncidium or cymbidium. I searched for photos of both and read their descriptions but they look the same to me. Without blooms, how can i tell what they are?
Generally though, a cymbidiums pseudobulbs are rounder and the leaves weave out of the top of them in several layers and look sort of like a braid. Oncidium leaves don't tend to do this once a pseudobulb is formed.
