In the palm of my hand is an opened Callirhoe involucrata seed head. The husk of the seedhead is on my fingers. A green seedhead is near the tip of my middle finger. A flower that doesn’t seem to be making a seedhead is just to the left of my index finger. I wonder if they have separate male and female flowers like squash?

  1. I looked up Callirhoe in the BRIT Flora. It says “Gynodioecy is known in a number of species (in this genus)”. Wikipedia says “Gynodioecy is a rare breeding system that is found in certain flowering plant species in which female and hermaphroditic plants coexist within a population.” So yes, they sure could have male and female flowers.
