The first one is Potinara Ah Chung Yo Yo "Little Goldfish". I can't detect any fragrance. I got it from Dan and Margie Orchids in Southwest Ranches. I'm crazy about this one! Just pretend that the left sepal didn't break off.
The second one is from Mickey's Orchids in Fort Lauderdale. It is labeled C. Netrasiri x B. nodosa. It has a pretty strong fragrance. I think it kinda smells like soap with a tad floral? I don't know what B. nodosa or C. Netrasiri smell like, so I have no idea if the fragrance is from one or a mix of both. She said that this cross blooms almost constantly for her, so I'm hoping it does the same hanging in my tree.

Thanks for looking!
