Each carpel is homo- logous with a leaf. Each carpel bears one or more seeds. A pistil of one carpel is simple; of two or more carpels, compound. Usually the structure of the pistil may be determined by cut- ting across the lower or seed- bearing part. Figs. 190,191, 192 explain. A flower may contain one carpel (simple pistil) as the pea (Fig. 190); several separate carpels or Knotweed, a very common but inconspicuous plant along hard walks and roads. Two flowers, en- larged, are shown at the right. These flowers are very small and borne in the axils of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bailey, L.
