 of the "ray" — and so partly

 delion, Hawkweeds, Chicory, 

 etc. 



The " umbels," as the 

 floral colonies of the Umbcl-

 the specialisation of the Com- 

 positcB, but not in the degree 

 in which altruism is carried 

 out ; but most if not all of 

 the outer flowers of this order 

 have larger petals than the 

 rest. So far, therefore, it 

 would appear as if their char- 

 acter were egoistic rather than 

 altruistic — that they were aristocrats, or plutocrats, 

 rather better off than their neighbours. But at any 

 rate the floral society of which they are members 

 are gainers thereby, for insects are attracted to 

 them all the more certainly for the extra conspicu- 

 ousness. None of these extra -developed members
