Thank you.

The vast majority of orchids are 'perfect' which means they have both male and female parts on the same flower. Some, like Cycnoches and Catasetums have separate flowers for each sex. It should be noted, however, that even Catasetums and Cycnoches can produce 'perfect' flowers that have both male and female reproductive organs on the same flower. In fact, the two female shaped flowers in my previous post on this thread were actually hermaphroditic. Thats why I said female shaped, rather than just saying they were female flowers. Usually Cycnoches and Catasetums have an "either or" system where flowers are clearly separated as male or female. Sometimes, as in the 'female shaped' flowers in my pictures, you get pollinia that grow on female shaped flowers, thus creating a hermaphroditic flower. Usually on these hermaphrodites, however, the pollen is not viable. Sometimes Catasetums will actually have male, female and even hermaphroditic flowers on the same plant at the same, sometimes even on the same spike! Needless to say, early botanists were completely baffled for decades!!:shock: This is one of the reasons that I like these two genera so much (as well as their close allies Clowesia and Mormodes, though these two genera have 'perfect' flowers). Theyre just so darn wierd!!
