as many as tliero are petals, — iIk; Flax has only five slamr'n.-.. .>- 

 just as many as tlie petals. Sucli flowers as these are said to be 



Perfect, uccause they are 

 provided with both kinds of 

 essential orjxans (23U), namely, 

 Stamens and pistils ; 



Complete, because th(>y have 

 all the sorts of oi'j^ans which 

 any flower has, namely, both 

 calyx and corolla, as well as 

 stamens and pistils ; 



Regular, because all the parts 

 of each set are alike in shape and size ; and 



Symmetrical, because they have an equal number of parts of ea?h 

 sort, or in each set or circle of 

 orjifans. That is, there are five 

 sepals, \\\(i petals, five stamens, 

 or in the Stonecrop ten stamens 

 (namely, two sets of five each), 

 and \\\{i ])istils. 



240. On the other hand, 

 many flowers do not jiresent 

 this perfect synnnetry and reg- ''* 



176 nlarity, or this completeness of parts 



injrly, we may have 



'241. Imperfect, or Separalt'd Flowers; which are 



those wliere the stamens and pistils are in separate 

 blossoms ; that is, one sort of flowers h;is stamens 

 and no pistils, and another has pistils and no sta- 

 mens, or only imperfect ones. The blossom which 

 lias stamens but no pistils is called a staminate or 

 sterile flt)wer (Fig. l"f>) » "'"^ •''*- corresponding 

 one with pistils but no stamens is called a pistil- 

 late or fertile flower (Fig. 177). The two sorts 

 may grow on distin«'t plants, from differont roots, 

 as they do in the Willow and I'oplar, the Hemp, and tiie Mooii-eed
