Lady's Purse in Longwood Gardens

The pocket of this Lady's Slipper is a little round and it does not look like a slipper any more. We should call it "Lady's Purse" instead. However, when we first saw it in the Longwood Gardens on 23rd March 2008, we thought there was something special about it. If you look at the purse, it is very transparent. You can almost see through. In fact, the inside wall has some light brown spots and we can even see the spots from outside.

Again, this is a very interesting Lady's Slipper. Unfortunately, we did not get a chance to write down the name of it. We were simply too busy taking pictures.
