The Blossom oj the Rhubarb 



, .TAf illustration shows the inconspicuous character of the 



individual blossoms oj the rhubarb, and the way in which they are 



massed together, as is usual with very small flowers. In hybridizing the 



rhubarb it is only necessary to dust one head oj flowers against 



another. Of course self-fertilization may take place in 



many coses, and it will be necessary to examine 



the seedlings themselves to determine 



which ones are hybridized.
