This striking Sonerila has recently become available out of SE Asia. I can’t find any publicly available papers describing the many Sonerila species so identifying them is rather difficult. For the first few weeks after import, it was especially sensitive and went completely limp a few times. After heavy soaking of the sphagnum, it rebounded each time and now is stable.
A year and a half later it’s stable on sphagnum and flowers often.
There has been talk of it being Sonerila maculata, but the iridescence on that species looks to be more exaggerated. It looks similar to heterostemon to me, but, it’s hard to say. That identification is based on an image taken by Patric Blanc, in this image gallery. His galleries are an excellent resource, and very inspiring!
And the flower. I recently started collecting the seed but have not sowed it yet.
