Suppose we start with the wild flowers: The first step is to purchase a popular illustrated book on this subject, preferably one in which the flowers are arranged according to color. We first learn, in the introduction, the principal parts of the flower, as the calyx, the corolla, the stamen and the pistil.
The racemes of purple bells held up by the foxglove are methodically visited by it, commencing at the bottom flower, and ascending step by step to the highest. The four stamens and the pistil of the foxglove are laid closely against the upper side of the flower. First a stamen on one side opens its anthers and exposes its pollen. The humble-bee, as it bustles in and out, brushes this off.
"Now, on one occasion, in a flower belonging to an individual of Salvia verticillata, and only on the left stamen, I observed a perfectly developed and pollinigerous lower cell, perfectly homologous with that which is normally developed in Salvia officinalis. This case of atavism is truly singular.
Upon the stalk of this column there appear from the front three lobes two small ones at the sides, each of which hides an anther attached to its under face the large terminal third lobe being in truth a barren rudiment of a former stamen, and which now overarches the stigma. The relative position of these parts may be seen in the under view.
The girl had heard of Owen: they met as enemies a very good way to begin an acquaintance. It was Nature's old, old game of stamen, pistil and pollen, that fertilizes the world of business, betterment and beauty. They quarreled. "You are the man who puts your name on the package?" "Yes." "And yet you own no mill!" "True but " "Never mind. You certainly are proud of your name."
The eggs correspond to the seeds; the various generations of aphides budding out from one another by parthenogenesis correspond to the leaves budded out by one another throughout the summer; and the final brood of perfect males and females answers to the flower with its stamen and pistils, producing the seeds, as they produce the eggs, for setting up afresh the next year's cycle.
Almost everybody knows that the function of the stamen is the secretion of pollen. This function, however, has really no reference whatever to the external form of the stamen. Why, then, this remarkable divergence?
A true, little-modified petal is drawn together on its upper margin, and produces a pollen sac, while the rest of the petal takes the place of the stamen. In double flowers we can observe this transition in all its stages. In several kinds of roses, within the fully developed and colored petals there appear other ones which are drawn together in the middle or on the side.
But if such a metamorphosis as this is possible if the seemingly wide gap between leaf and stamen may be spanned by the modification of a line of organisms where does the possibility of modification of organic type find its bounds? Why may not the modification of parts go on along devious lines until the remote descendants of an organism are utterly unlike that organism?
