Okay, how about this one: I have a species named Thrixspermum amplexicaule, of the Vandaceous alliance. The flowers open for just a day, but in succession. Once in awhile I find a flower open. I find them attractive in a devious sort of way. Well, I'm always trying to pollinate it. There are no registered crosses with other genera (Rumrill tried several times without success). I'm trying to make history here. I could be known as the guy who... well... did the first Thrix outcross or something.

The problem is, I can't find the stigmatic cavity. This is funny. I have pollinated hundreds of flowers of other genera before without a problem. When I go to pollinate this one, I find no cavity and no stickyness where the stigmatic cavity is supposed to be. I can't get anything to stick to it. The lip is in the right place, right below it, it looks like an inverted white thimble with a very small opening. Only one way in and out, but above it... nothing. Is this weird or what?
