 distinguished by the form of the fruit.

 class, Diadelphia, are founded on the number of stamens, that 

 is, on the characters of the first twelve classes, and they have 

 the same names as Monandria, &c.

 by different circumstances of the florets, as ;

is, each floret has a stamen, a pistil, and one seed. Such 

 florets are called perfect.
