ET^RIOS; MULTIPLE, AGGREGATE, AND 

 COLLECTIVE FRUITS. 



" 'Tis a long lane that has no blackberries in it." 



Old Proverb. 



" is the word, slightly altered in the 

 spelling, and omitting the initial h, which 

 the ancient Greeks used to denote com- 

 munities, partners, colleagues, comrades, 

 clansmen, etc. In Botany it has been in- 

 geniously adopted as the technical name for 

 some very curious forms of fruit, which, although simple 

 in appearance, are constituted, in reality, of a multitude 

 of little separate and independent fruits, every one of 

 them perfect in itself, a pericarp containing a seed. 

 Fruits of this description etaerios are produced by 

 buttercups, anemones, potentillas, and other members
