Pollen-Bearing Grape 



The members of the grape family, like the strawberry, 



differ as to the character oj their flowers. Some plants bear 



perfect blossoms, others are staminate with at most a rudimentary 



ovary. The plant thus occupies an intermediate position betiveen 



those plants that all bear perfect flowers and those that 



always bear the stamens and pistils on separate 



blossoms. The various arrangements suggest 



the need of cross -fertilization in 



the economy of plant life.
