Dusty ----- I seriously got taken by surprise on the very first time it bloomed (not this time, but soon after I first bought it). The leaves were really just a few inches (eg. 3 inches long) ------ and it just developed a flower spike. It surprised me. I wasn't expecting that for such a small plant.
This one really has pretty short leaves. Definitely a miniature oncidium. Some nursery sites have the description of it as miniature oncidium.
