petals, Pi^ht stnnions (twice four), and four pistils. So the flower of I'rilliuni (Fig. 



162) is .symmetriciil ; fur it consists of three sepals, three petals, six stamens (one 



before each scp.-ij .md one hcforc each petal), and 

 a pistil plaiidy composed of three put to^fether, 

 haviniif three stales or stitrmas. I''l,i\ alVords an- 

 other L'ood iUustration of symmetrical flowers 

 ( ¥\\i. I 70) : it has a calyx of five sepals, a coroUa of 

 five petals, live stamens, juid live styles. In such 

 flowers, and in hlossoms <,'enerally, the piirts (tlhr- 

 naf'' with each other; that is, the petals stand he- 

 fore the intervals between tlie sepals, the stamens, 

 when of the same number, before tlie intervals 

 betweeji the pc't.-ds, and so on. 



20S. An Unsymmetrical Flower is one in which 



the different or^'ans or 



sets do not matcli in 



tlie number of their 



parts. 'I'he flower of 



Anemony, V'\)i. 163, is 

 5 unsymmetrical, liavin<jf 



many more stamens 



and pistils than it has 



calyx-leaves. And the 



blossom of Larkspur 



(Fifj. 171), is unsym- 

 metrical, because, while 



it has five sepals or 

 leaves in the calyx, there are only four petals, or co- 

 rolla-leaves, but a ^reat many stamens, and only one, 

 two, or three pistils. The sepals and petals are dis- 

 played separately in Fig. 172 ; the live pieces marked 

 « are the sepals ; the four marked 7) are the petals 



209. A Regular Flower is one in which the parts of each .sort are all of the same 

 shape and size. The Howers in Flax (Fig. 1 70) and in all the examples pre- 

 ceding it are regular. AVhile in Larkspur and Monkshood we have not only an
