Flower Sex Expression
Plant Types
Monoecious - Plants carrying both male and female flowers
the same plant (cucumber, corn)
Dioecious - Species in which separate male (staminate) and
female (pistillate) plants exist
(Date palm, papaya, spinach, hemp, ginkgo)
Andromonoecious - Plants carrying both male and perfect flowers the same plant (muskmelon)
Gynomoecious - Plants carrying both female and hermaphroditic
flowers on the same plant (some cucurbits)
Trimonoecious - Plants carrying make, female, and hermaphroditic
flowers on the same plant (some cucurbits)
