A large-flowered epiphyte endemic to the cloud forests of Ecuador, exceptional in a genus known for miniatures. The broad, rounded dorsal sepal and wide connate lateral sepals are uniformly vivid chartreuse-yellow with fine parallel veining, framing a clean white-cream center — a bold, luminous bloom that fully justifies its name.

Watering: Water thoroughly and allow the mount or medium to approach dryness between waterings; avoid prolonged root saturation.
Additional Notes
Best grown mounted on cork or tree fern; a small net pot with fine bark also works well. A slight nighttime temperature drop encourages blooming. Plants are shipped bare root and well-established.
