I can tell you this much: the plant's heritage involves Oncidium maculatum, leucochilum, and fuscatum too, i'd bet. Give it lots of light year round, it will happily take sun in the mornings and afternoons. In the winter, if you dont have artificial lights, keep it in the brightest place possible. Let it dry completely before watering again (thats why its in such a small pot—dries faster!) After the flowers are finished, the plant will begin to grow new pseudobulbs. It should be repotted at that time into a slightly bigger pot.
Keep me updated! I miss my Cambria but I enjoy helping with yours!
