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

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

 number of cells in the ovary, or (when only one cell) by the 

 number of seed-rows. Thus the three-lobed stigma or ovary 

 of the Lily indicates a triple pistil, also the three stigmas ol 

 the Spring Beauty, and the three seed-rows in the Violet.

127. But when the pistils remain separate and distinct w€i 

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

 there are five simple pistils ; in Anemone (Fig. 207), 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.) 



126. Please tell us how you detect tlie number of carpels in tlie compound 

 ovary of Spring Beauty ; of Lily ; of Violet. 



127. What peculiarity in the form of a simple pistil?
