How long ago was this needing care? It rebounded beautifully!
You can never be sure, but that sure looks like Oncidium 'Twinkle' or some sibling of it. 'Twinkle' and it's sibs are known to smell like lavender soap or vanilla with colors ranging from white to dark pink. We have one at the Indianapolis Museum of Art greenhouse that scents up the entire greenhouse when in full bloom. I really need to get one as my partner really like scented blooms and this give me another reason to purchase "just one more".
Thanks for the post - it just goes to show the vigor of the Orchid family.
Have a great season -
Steve
