First there is the simple pistil composed of a 

 single carpel leaf. You can see one in the common 

 pea or bean. If you look at one of their flowers you 

 will easily see its single carpel, folded so as to form 

 its single ovary : and you know it very well when it 

 has ripened into fruit: the pod, either of the pea or 

 bean. (Fig. 15 d, p. 21.) Then you can seethe mid rib or 

 vein of the carpel leaf very plainly along the back * or 

 ridge of the pod : and it easily splits open both along 

 the mid rib at the back, and also all along its under 

 side where the edges of the folded carpel leaf had 

 joined t to form the ovary, which has now become the 

 A. pistil of this kind then, formed of a 

 single carpel, is called a simple 

 pistil. (Fig. 98.) 



But very often the pistil is composed 

 of more than one carpel. This is so, 

 you remember in the buttercup. Look 

 at it again (Fig. 23) and notice its many 

 separate carpels, each formed into a 

 separate ovary. So this kind of pistil is 

 called an apocarpous J pistil (cf. Fig. 99). 

 But besides the simple pistil of the pea 

 / torus, f ovary, or bean, with its single ovary ; and the 



g style, 11 stigma, 



/; ventral suture, apocarpous pistil as in the buttercup, with 



* This is called the ''dorsal suture ;" from the Latin " dorsum" the 

 back ; and " sutura ; " fr. " suo," I sew ; a seam along the back. 



f This is called the ventral suture, fr. the Latin "venter" the belly ; 

 and snlttra as above. (f/"Figs. 9&/>. 99). 



I From the Greek " apo" apart from, and " karfos " (carpeJs) ; 

 carpels forming separate ovaries.
