Possibly Cattleya labiata (or hybrid) and that's just a guess. Might have a new name, taxonamy in orchids is hard to follow sometimes. Very nice flower, I wish I could grow flowers like that. Shaun
Unless you know where the plant came from and can contact the source for an id it is almost fruitless. Here is a Google link of purple flowered cattleyas. http://images.google.com/images?q=p...rosoft:en-US&ie=utf8&oe=utf8&um=1&sa=N&tab=wi
