Part 111. The poppy order (Papaverales or Rhoeadales) comprises a few families well represented by the poppy and the mustard families and agreeing in having mostly racemose inflorescences of complete, hypogynous, regular or irregular flowers with the sepals, petals, and stamens all distinct and free, and a compound pistil with parietal placentae. It is the union of the carpels by their edges which mainly distinguishes this from the crowfoot order.

For comparison we have a typical formula of the order on pages 408, 409.
