24 DIRECTIONS 



As the "Guide" is intended primarily for the gen- 

 eral observer, a flower-head, whether of the Composite 

 family or otherwise (as the bunchberry, or the flowering 

 dogwood) is classed as a single flower, since it has that 

 appearance; aggregations of leaves resembling flowers, 

 and giving the distinctive color, as in the painted cup, 

 are classed among the flowers. 



Classification by colors implies some latitude; the 

 general color-effect determines the placing of the flower; 

 in case of doubt between purple and pink, the first 

 choice falls to purple.
