The Blossom oj the Rhubarb 



The illustration shows the inconspicuous character of the 



individual blossoms of the rhubarb, and the way in which they arc 



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 selj-jertilization may take place in 



many cases, and it will be necessary to examine 



the seedlings themselves to determine 



which ones are hybridized.
