The stamens vary in number, from one to many hundred. Like the other parts of the flower, they are modified leaves, resembling them in their structure, development, and arrangement. They consist of cellular and vascular tissue. They appear at first in the form of cellular projections, and are arranged in a more or less spiral form. In their general aspect they have a greater resemblance to petals than to the leaves, and there is often seen a gradual transition from petals Fig. 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 Balfour, John Hutton, 1808-1884.
