THE CALYX.

The calyx is green.

The calyx is strong.

The calyx protects the ovary.

It has five sepals—five green sepals.

They overlap like the tiles on a roof and thus protect the ovary from rain. They also protect it from insects that otherwise might destroy it.

The calyx covers the base of the corolla and forms a green urn, a little vase, in which to hold it secure from harm.

It is not bright and delicate like the corolla, but what would the flower do without it?
