My grandfather has had this orchid for well over a decade. Probably two. I've inherited one huge mother plant, and 5 or so smaller divisions from him. Sadly, I have no ID for many/all of his plants. Most I probably wont get ID'd, but I think this is Blc. Rustic Sports. Hopefully I can get a few confirmations. Imgur: The most awesome images on the Internet
Looks more like Pot. Hoku Gem, the lip isn't frilly enough for Rustic Spots - both, I believe, have Richard Mueller in their backgrounds. Of course, I have to say the obligatory 'once a NOID, always a NOID.'
It is a beauty no matter what. I love, love, love orange, spotted catts!
I agree with Salixx. Not Rustic Spots, similar to Hoku Gem. Even though similar, I would not tag it based on an online ID. Consider it a NOID, and just use the tentative IDs as cultural guidance.
