So tlie floAver of Trillium (Fi 162) is symmetrical; for it consists of three sepals, three petals, six stamens (one before each sepal and one before each petal), and a pistil plainly composed of three put together, having three styles or stigmas. Flax affords an- other good illustration of symmetrical flowers (Fig. 170) : it has a calyx of five sepals, a corolla of five petals, five stamens, and five styles. In such flowers, and in blossoms generally, the parts alter- nate "vvith each other; that is, the petals stand be- fore the intervals between the sepals, the stamens, when of the same number, before the intervals be- tween the petals, and so on. 208. An Uiisymmetrical Flower is one in which the different organs or sets do not match in the number of their parts. The flower of Anemony, Fig. 1G3, is unsymmetrical, having many more stamens and pistils than it has calyx-leaves. And the blossom of Larkspur (Fig. 171) is unsym- metrical, because, while ^ (r~"~~^^^p^ it has five sepals or leaves in the calyx, there are only four petals or co- rolla-leaves, but a great many stamens, and only one, two, or three pistils. The sepals and petals are dis- played separately in Fig. 172; the five pieces marked 5 are the sepals; the four marked p 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 flowers in Flax (Fig. 170) and in all the examples pre- ceding it are regular. While in Larkspur and Monkshood we have not only an unsymmetrical, but.
