Well if you haven't a tag the only sure thing is that it's a Bulbophyllum and that is very cute with those rounded little bulbs with no signs of wrinkles!
You can give him a name that of course is not a true registered clone but can be useful for you, to remind you of which plant you're talking about.
Use the double quotes as single ones would be used for a registered clone/cultivar.
I'd propose
Bulbophyllum sp. "Cute maybe fostii"
