Possibly Cattleya Peckhaviensis? Another similar looking one is cattleya guttata. Both of these have brownish spotted petals and pink lips. You can do a search on google images of these names. Some look pretty close. Any other ideas?
You're welcome! I just happened to come across that picture in my orchid book. By the way, that's a really pretty cattleya! I'm planning to get a catt myself someday...
