Coming to the flower itself, direct your attention, first of all, to the position of the ovary. You will find it apparently under the flower, in the form of a tube tinged with purple. It is not in reality under the flower, because its purplish covering is the calyx, or, more accurately, the calyx-tube, which adheres to the whole surface of the ovary, and expands above inco four long teeth. The ovary, therefore, is inferior, and the calyx, of course, superior, in this flower. As the sepals unite below to form the tube the calyx is gamosepalous. The corolla consists of four petals, free from each other, and is consequently polypetalous. It is also regular, the petals being alike in size and V shape. Epch petal is narrowed Pig_ 42.

The stamens are eight in number (octandrous), four short and four long, and are attached to the calyx (perigynous). 46.
