A SYCAMORE "FOUR-IN-HAND" 



Ordinarily the flower heads of the oriental sycamore {Platanus orientalis), a 

 shade tree widely grown in the United States, occur singly. But some- 

 times two, three, or even four are joined together, in which cases the 

 stems are in line with each other. Photograph by Dr. R. W, Shufeldt.
