filaments, and the yellow heads, or anthers, were 

 both together the stamens ; and the thicker thread, 

 that stands in the middle of them, the pistil.

 difference at once, in examining plants of these 

 two classes, the surest way is to pull off the calyx 

 gently, and then, if the stamens remain, you may
