 kind of pistil. You have already 

 seen it in the flower of the 

 primrose. Do you remember it? 

 We will find a primrose flower 

 if we can, and look at its pistil as 

 we did before, " the little round 

 green bag and from it the slender 



Fig. 99- Apocarpous knobbed stalk like a m-een and 



pistil of Monkshood 



(Aconituui napeilus}. t, tender pin " (p. 10). This pistil,

like that of the buttercup, is com- 

 posed of two or more carpels ; but they have so grown 

 together as to form only one 

 ovary. This kind of pistil is 

 therefore called syncarpous* 

 (cf. Fig. 100.) Perhaps you 

 think the syncarpous pistil of 

 the primrose looks as if it was 

 composed of a single carpel 



leaf, and so would have called ,,.

not say so if you were to cut off the style and stigma 

 and look at the ovary through a good magnifying 

 glass or low powered microscope ; you would then 

 see the joining of its carpels quite distinctly. 



So then you have the three kinds of pistils : (i) the 

 pistil of one carpel, which is called simple ; the pistil

 together, forming one ovary.
