Orchid flowers

Orchid flowers have a simple underlying plan. There are three sepals, three petals. One of the petals is called the labellum, and is usually very different from the other two. The final part is the column, which bears both the stamen and the stigma. The ovary is inferior. The variation in these simple structures is remarkable.
