SITF confirms this plant is Oncidium luteum (Jan 2024). Plant identification was confirmed at the judging session by the noted taxonomist, Dr. Franco Pupulin. The crest of this species consists of two flat blades that stick out 90 degrees and three tooth-like projections that point toward the midlobe. This is very distinctive and and clearly visible in the enlarged photo of the flower. A good image of this species can be seen in the IOSPE, which is almost identical to this flower.
