This came as a gift from someone. There is no tag of any kind. I don't know anything about spider orchids. So at the very least a genus and some care instructions would be nice.
It's obviously very "heavy" in brassia content, so if you look up Brassia verucosa, that ougth to give you a decent handle on the culture.
FWIW, I find that intermediate temps, bright, indirect sun, and average humidity is fine. I grow all such Oncidiinae intergenerics in semi-hydroponics.
