thanks Jim!!
So many different medusas, I had no idea!
Regarding the Bulbphyllum medusa, I find them very susceptible to black rot, especially right after blooming. Some years ago I had one blooming for me in most wonderful fashion, only to DIMP spectacularly right after that. One by one every growth turned to mush on me. It looked to me like the plant bloomed and then was simply done.
I still have two small plants, once in a while they actually produce a good growth to bloom. I don't know why I still try to grow them. Good compost!
