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

 stigmas, or by the lobes of the stigma or ovarj'-, 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 

 o£ the Lily indicates a triple pistil, also the three stigmas of 

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

the stjie single, simple, and lateral. 

 Fig. 216. Section of flower of Jefiersonia, — stamens hypogynous, pistil single, 



simple, with one seed-row. 



127. But when the pistils remain separate and distinct we 

 call yach 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.) 



136. Please tell us how you detect the numier of carpels in the compound 

 ovajy of Spring Beauty ; of Lily ; of Violet.
