To what extent strategies traditionally interpreted as "male" also benefit female fitness in other species remains an open and interesting question. In dioecious plants, only cross pollination can occur due to the presence of one types of flowers in the plant.
The experimental demonstration that male flowers can sometimes increase seed number supports a new interpretation that male flowers increase not only male but also female reproductive success. The main difference between unisexual and bisexual flowers is that unisexual flowers contain male and female reproductive organs in separate flowers whereas bisexual flowers contain both male and female reproductive organs in the same flower.
