I have a picture of a pretty orchid at the Missouri Botanical Garden here in St Louis. It was unnamed but I thought it was pretty enough to post to the database under a generic 'orchid' category. Unfortunately, it looks like the orchid database is divided into categories and I don't have a clue which type of orchid this is. I know there are a gazillion named orchids, but can someone narrow down the type of orchid for me? Thanks!
