Thanks, Gin. I think it's a nice plant, too.

I did a little reading about peloria, but most of what I found seemed as though it was sort of all or nothing - a mutation that conferred the irregularity consistently, or normal flowering. A couple other places chalked up some occurrences to possible hormonal imbalances or something similar, so I wanted to correct this if I was mishandling the orchid in some way. I can read as well as anyone, but I don't have the experience to know what subtle signs I might be missing: thus, to the experts! Knowing that at least one person who knows what they're doing experiences a similar issue is comforting and suggests that it might just be random.
I'll keep to the current regimen based on the advice I've been given. When the blooms drop, I'll repot it. Perhaps I'll follow up with some pictures around that time.
Thanks again,
Dan
