Look for the flowers with the long and thin stalks. These are the males. They'll typically appear before the female flowers, and they'll also be more abundant. - 2

Look for the stamens. Another distinguishing feature of the male flower is the presence of what appears to be a single stamen --- the rod-shaped, pollen-producing part of the flower that protrudes from the center. On a male pumpkin flower, however, what appears to be only one stamen is actually more than one stamen fused together. - 3

Look for the flowers with the short and thick stalks. These are the females. Underneath the female flower, you'll also notice a green, berry-sized ovary --- the part that swells into a pumpkin after fertilization takes place. Fertilization is also followed by the shriveling up of the female flower. - 4

Look for the stigma. Female flowers can be identified by the multi-segmented stigma in the center. The stigma is the pollen-receiving part of the flower.
