pistil by tlie number of separate styles, or by the separate 

 stigmas, or by the lobes of the stigma or ovary, or by the

127. But wlien the pistils remain separate and distinct we 

 call each one a siuiple pistil. Thus in Columbine (Fig. 209) 

 there are five simple pistils ; in Anemone (Fig. 20Y), and in 

 Buttercups, many ; while in Cherry, Peach, Bean, Alchemilla, 

 and JefFersonia, there is just one simple pistil in each flower. 

 Such a pistil is usually of an irregular form, with its style 

 lateral (on one side), and only one seed or seed-row. (See Figs. 

 215, 216.)

 ovary of Spring Beauty ; of Lily ; of Violet.
