272. Number of Pistils. — Taking the Greek numerals, 

 with the Greek poly, — as we did for the stamen, — and 

 prefixing them to the root gyn (woman, pistil), we have the 

 same descriptive terms for the gynoecium, — monogynia, etc. 

 Besides these, the pistil — which is also called Carpd, espe- 

 cially when there is more than one in the gynoecium — is : 

 Monocarpous when there is but one ovary, as in the Pea 

 (Fig. 5, 6) ; Syncarpous when there are two or more 

 ovaries, as in the Lily (Fig. 6, 4) ; Apocarpous (Gr. apo, 

 from, separate) when there are many distinct carpels, as in 

 the Buttercup (Fig. 9, 1). 



273. The Position of the Stigma in regard to the Style is Terminal 

 when the conducting tissue is at the 

 apex (Lily) ; Unilateral when on 

 side (Custard-Apple) ; Bilateral when 

 on both sides (Plantain). ' 



274. In Form 

 the Stigma is Capi- 

 tate (head-like) in
