A close-up of the same flower, showing the spotted lip. Just above the lip is the gynostemium or column, formed from the fusion of the male and female reproductive organs.
All orchids have a column rather than separate stamens and pistils.
I believe this is the same hybrid shown in the previous two photos, though it was taken a year later. The 800x600 version shows the tiny hairs on the petals. 800x600 Paphiopedilum insigne albo-marginata. This is the same plant, though not the same flower, as is shown in Nero Wolfe's Orchids . 500x375 Paphiopedilum insigne, a slipper orchid native to Nepal and Northeast India.
