Pollen-Bearing Grape 



The members oj the grape family, like the strawberry, 



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



perject blossoms, others are stammate with at most a rudimentary 



ovary. The plant thus occupies an intermediate position between 



those plants that all bear jierject flowers and those that 



always bear the stamens and pistils on separate 



blossoms. The various arrangements suggest 



the need oj cross-Jertilization in 



the economy oj plant lije.
