A staminate flower is a male flower, bearing only stamens. A pistillate flower is female, bearing only pistils.
A monoecious (pronounced moan-EE-shus) plant has separate male flowers and female flowers occurring on the same plant. Plants that are dioecious (die-EE-shus) have either staminate or pistillate flowers on separate plants. Some wild American grapes are dioecious, with male plants unable to produce fruit.
