The tag said 'Twin,' but the internet says it's 'Twins,' and PATSP is on the internet, so.
If this looks familiar, that's probably because it's the offspring of a previous orchid, Psychopsis Kalihi.
If it looks shitty, blame the brown background and the other orchids in the shot -- this was a bear of a photo to edit. I stopped editing not because I felt I'd gotten the best photo I was going to get, but because I was too frustrated with it to continue.
Psychopsis Mariposa 'Twins' = Psychopsis papilio x Psychopsis Kalihi (Ref.)
