I bought this miniature phal some years ago, and lost the tag somewhere along the line. No records at all. I purchased it either Normans or Carter and Holmes. The flower is about 1.5" in dia. the plant after a number of years, is still in a 3" pot.
It's lovely, but no idea as to the identification. Could you check with the folks as Norman's or Carter & Holmes? Hopefully they will remember. Then let us know! It would go on my list if there was a name.
