Identification please

[Brenda Aarts]

Any idea on what type of orchid this is presently in spike? Large oncidium green and burgundy spotted bulbs & large thick heavy leaves. Thanks for any suggestions.



The second plant has many more leaves and they are a light green, but still very thick, 3 x that of gongora types. A spike is coming up between 2 leaves and another on the outside of the bulb. Spike is green with some burgundy. Both plants were brought home from an auction recently so it's a bonus that they are even doing anything, thought likely more easily identified when in bloom. Thanks for any help.
