The passion flower model is my design. I folded the flowers in the picture with duo and patterned kami paper: 3" (75 mm) squares for the petal modules, and 2" (50 mm) squares for the stamen modules.
The passion flower petals consist of four "3 Pajaritas"modules that are joined with a stamens module. I called the petals module "3 Pajaritas," because it's just that. It's obtained by dividing the paper in quarters and then folding a traditional spanish pajarita in three of them. The stamens module is a bird base upside down, where each petal is folded inside in half, and then folded down.
The pictures below show the crease patterns and a detail of the modules.
