Cucurbit has unisexual flowers carrying either male or female reproductive organs. Flowers with male reproductive organs (stamen) are termed as staminate flowers. while those carrying only carpel, are termed as pistillate flowers. Other examples of unisexual flowers are papaya, watermelon, maize etc.
