I saw this listed as B. japonicum (Laos) in NT Orchids. I was curious what it was, so I purchased it in 2019. It turned out Bulbophyllum levinei. Very compact plant, and I like it (even though the individual flower is small). I put more dissected flower photos in my blog post (link). The photo is from May 30, 2020. I haven't had time to post it.
