Style arms of center fls. terminated by a cone . 

 Style arms not terminated by a cone 



b. Anther lobes each with a tail, the tails of adjacent

i The characters separating these genera are unsatisfactory. Conyza 

 is widely separated from Blumea in tbe B.B.I, and included in the 

 Asteroideae, but it seems in some respects more naturally included in the 

 Inuloideae. The anther lobes are often tailed, and the style 'characters 

 not at all well marked.
